PortSignal — Terms of Service

Last updated: 23 April 2026

About the Platform

PortSignal is a gated marketplacefor maritime lineup data. Access to Feed listings, pricing, and data is restricted to Buyers who have registered and passed Signal's vetting. No Feed content, listing, or metadata is made publicly available.

By accessing or using the Platform, you agree to these Terms of Service ("Terms"). If you do not agree, you may not use the Platform.

1. Parties and Acceptance

1.1 The Platform operator. PortSignal is operated by Signal Ocean Ltd(company number 09297294, incorporated in England and Wales on 5 November 2014, registered office 83 Cambridge Street, Pimlico, SW1V 4PS, London, England) ("Signal", "we", "us"). Signal Ocean Ltd is a UK VAT-registered company; our VAT registration number appears on invoices and can be provided on request.

1.2 Authority to bind. If you accept these Terms on behalf of an organisation (Buyer, Data Contributor, or otherwise), you represent and warrant that you have authority to bind that organisation. All acts under your account are attributable to the organisation you identify as your employer or principal.

1.3 Enterprise-specific agreements. Where Signal and a user have separately signed a written agreement (for example, a bespoke Master Services Agreement, Data Processing Agreement, or enterprise addendum), that signed agreement supersedes these Terms to the extent of any conflict, for that user only.

2. Definitions

• "Basket"— a bundle of Feeds subscribed to as a single line item, priced and invoiced together.
• "Buyer"— any individual or entity accessing, trialling, subscribing to, or consuming Feed data through the Platform.
• "Data Contributor" (or "Contributor")— any individual or entity that provides, uploads, curates, or publishes data on the Platform.
• "Data Contributor Manager"— a Contributor-side user with additional permissions (view revenue and payout details, manage team, receive trial and subscription notifications).
• "Feed"— a packaged dataset listed on the gated marketplace by a Contributor.
• "Feed Output"— the normalised delivered version of a Feed as produced by the Platform (raw lineup data plus Signal's normalisation and reference data).
• "Freshness SLA"— the update cadence a Contributor commits to for a Feed.
• "Platform"— the PortSignal website, APIs, tools, and services operated by Signal.
• "Reference Data"— Signal's vessel database, commodity tree, port database, and benchmark data.

3. Accounts

3.1 Registration information. You must provide accurate and complete information. Buyers provide: email, company name, country, title/role. Contributors provide: first name, last name, email, phone, and an alias (used for anonymous publishing, where elected).

3.2 Minimum age. You must be at least 18 years old.

3.3 Authority and responsibility. You are responsible for all activity under your account. You must keep account credentials confidential. Where multi-factor authentication is offered, enabling it is strongly recommended.

3.4 Account ownership transfer.The account is bound to the organisation (not the individual). If the user who originally registered leaves the organisation, a successor owner may be appointed by written request to Signal, supported by evidence of the organisation's internal authority to make the change (e.g. corporate email domain, HR letter, Companies House record). Pending verification, the account remains accessible on a read-only basis.

3.5 Data Contributor Manager role. Account owners may designate one or more Managers with elevated permissions. Managers are bound by all Contributor obligations in these Terms. The account owner remains legally responsible for all activity under the account.

3.6 API keys (Buyers). Buyers receive a single API key per organisation. You must:

• keep the key confidential;
• notify Signal within 24 hours of any suspected compromise;
• not expose the key in public repositories, screenshots, client-side code, or logs;
• accept full liability for all use under your key, including unauthorised use enabled by your failure to protect it.

Breach of this clause may trigger suspension and liability under §12 (Indemnification) and §14 (Liquidated Damages).

4. Data Contributor Terms

4.1 Data rights warranty. By publishing a Feed, you represent and warrant that you have all necessary legal rights to sell the data contained therein, and that doing so does not violate any existing agreements, contractual obligations, or third-party rights. You re-warrant this at each Feed publication event.

4.2 Data ownership.Raw lineup data contributed by you remains your property. Signal's normalisation tooling (vessel database, commodity tree, port database, extraction pipelines) does not transfer ownership of your underlying data to Signal.

4.3 Distribution licence.By publishing a Feed, you grant Signal a non-exclusive licence to list, display, and resell the Feed to vetted Buyers through the PortSignal gated marketplace. Listings, pricing, and metadata are only visible to approved Buyers. You may withdraw your Feed at any time, which terminates future distribution; existing Buyer subscriptions continue until the end of their current billing period (subject to §16).

4.4 Commission.Signal charges a commission on all transactions at the applicable rate shown to you in the Contributor dashboard at the time of subscription or Basket-line creation. The commission is added to your set price; the Buyer pays your price plus the commission; you receive your full set price. The applicable commission rate is locked at the time a subscription or Basket-line is created and does not change for the life of that subscription. Commission rates may be updated prospectively for new subscriptions at Signal's discretion.

4.4.1 Historical commission records. Basket commission records prior to Platform version 1.36 may be incomplete due to a historical data gap. Signal honours the commission rates in effect at the time of each transaction; requests relating to pre-v1.36 basket receipts should be directed to your Partnership Manager.

4.5 Freshness SLA.You commit to an update cadence at Feed publication. Signal measures time-since-last-update against a threshold configured by Signal. Feeds exceeding the threshold may display a stale-data warning to Buyers, may be downranked in the marketplace, and — if staleness persists — may be suspended, with payouts paused until updates resume. No retroactive clawback of payouts applies. Buyers continue to be billed during warning and downrank periods.

4.6 Anonymity.You may publish under an alias ("Anonymous Contributor"). Anonymity governs identity disclosure only: your Feed remains available to vetted Buyers in the gated marketplace under the alias. Signal acts as reseller of record and never discloses your legal identity to Buyers. Signal holds Anonymous Contributor legal identities in an isolated vault; such identities are shared only (i) with Stripe as required for KYC and payouts, (ii) on a valid legal order from law enforcement, or (iii) on a legitimate compliance or fraud-investigation trigger. Anonymity does not make a Feed private or restrict which vetted Buyers may subscribe.

4.7 AI-assisted processing.Files, emails, and content you upload are processed by Signal's third-party AI services (currently Anthropic Claude) for data extraction and normalisation. By uploading, you authorise this processing. Signal does not permit uploaded content to be used to train third-party models.

4.8 Contributor exclusivity.You remain free to sell, licence, or distribute your raw underlying data to any other party or platform. You may NOT, however, lift the Feed Output (the normalised and enriched output produced by the Platform) and redistribute, resell, or publish that output elsewhere. Signal's normalisation and reference-data layer is Signal's intellectual property applied to your data.

4.9 Data accuracy — no warranty, no liability to Buyers.

(a)All data you contribute is provided on an "as-is" and "as-available" basis. You make no representation, warranty, or guarantee — express, implied, or statutory — regarding the accuracy, completeness, timeliness, reliability, or fitness for any purpose of the data you publish.

(b)To the fullest extent permitted by applicable law, you shall not be liable to Buyers, to Signal, or to any third party for direct, indirect, incidental, consequential, special, punitive, or exemplary damages — including lost profits, lost opportunities, trading losses, demurrage, charter-party disputes, or business interruption — arising from inaccuracies, errors, omissions, delays, or unavailability of the data you contribute.

(c) Carve-outs.The shield in §4.9(b) does not apply to: (i) your warranty in §4.1 that you have the legal right to sell the data; (ii) fraud, willful misconduct, or intentional misrepresentation; (iii) any liability that cannot be excluded or limited under mandatory applicable law.

4.10 Buyer exclusion list. You may maintain a list of Buyers excluded from seeing or subscribing to your Feed(s). Excluded Buyers will not see the Feed in the marketplace and cannot subscribe. You may update this list at any time. Signal is not required to explain an exclusion to the Buyer.

4.11 Tax on payouts. You are solely responsible for reporting and paying any income, VAT, or similar taxes on amounts you receive through the Platform. Stripe may issue IRS Form 1099-K or equivalent tax documents for US Contributors in accordance with applicable law.

4.12 Payouts.Payouts are processed via Stripe Connect, 15 days after Buyer payment confirmation. Signal may adjust this timing with 30 days' written notice. Commission is deducted before transfer.

5. Buyer Terms

5.1 Data-use licence and internal-use restriction.Data accessed or received through PortSignal is licensed to the Buyer for internal business use by the Buyer's legal entity and its downstream wholly-owned subsidiaries only. For these Terms:

• "Wholly-owned subsidiary" means an entity in which the Buyer directly or indirectly holds 100% of the voting equity.
• Parent companies, sister companies, and any entity that owns the Buyer are excluded (prevents upstream leakage in the event the Buyer is acquired).
• Affiliates whose business includes providing data, SaaS, software, analytics, or information services to third parties are excluded even if 100%-owned — they require Signal's prior written approval and a separate subscription.

You may not, and may not permit any third party to:

• (a) resell, redistribute, republish, sublicense, or share Feed data, in whole or in part, in any form;
• (b) make Feed data available to any third party, including via API, file export, dashboard, report, screen share, or derivative product;
• (c) use Feed data to create a competing data product or a substitute dataset offered to third parties;
• (d)share API credentials outside the Buyer's legal entity and its permitted wholly-owned subsidiaries;
• (e) use Feed data to identify, solicit, or contact a Contributor outside the Platform with the purpose of circumventing Signal;
• (f) attempt to identify any Anonymous Contributor from the data or metadata;
• (g)engage external consultants, contractors, or advisers in a manner that would require sharing Feed data with them (Feed data is strictly for the Buyer's permitted corporate group).

Derivative analytics produced solely for the Buyer's internal decision-making are permitted. Machine-learning / AI models trained on Feed data must be used internally only; the trained models, their outputs, and any derivatives carrying Feed-derived signals are subject to the same restrictions and may not be shipped, licensed, sold, or made available to third parties. Aggregated or anonymised insights that cannot be reverse-engineered to Feed data may be shared externally.

External publications — including presentations, reports, or commentary citing Feed data — require Signal's prior written consent and may require Contributor consent where the Contributor is non-anonymous.

Reselling, redistribution, and sublicensing are absolutely prohibited. No written-approval path exists. Breach of this §5.1 is a material breach and triggers §14 Liquidated Damages and §12 Indemnification.

5.2 Trial. Buyers may start one 2-week free trial per Feed per Buyer organisation. Credit card is not required to start a trial. Signal may revoke any trial at any time, for any reason, without refund (trials are free; no refund is payable).

5.2.1 Trial data — no permanent licence.Data received during a trial is provided for evaluation purposes only. If the Buyer does not convert the trial into a paid subscription, the Buyer must delete all data received during the trial within 30 days of trial expiry and has no retention or continuing-use right in that data. If the Buyer converts to a paid subscription, the trial-period data becomes part of the Buyer's paid-subscription footprint and is subject to §5.3.

5.3 Subscription, cancellation, and data retention after cancellation.

Subscriptions are billed monthly in advance via Stripe. Cancellation takes effect at the end of the current billing period; no pro-rata refunds are payable. A formal dispute-and-refund process may be introduced; any material change to this refund policy will be notified 30 days in advance.

Permanent internal licence on received data.Data received while the subscription was active may be retained and used internally by the Buyer indefinitely after cancellation. However, all §5.1 restrictions (no resale, no redistribution, no sublicensing, no affiliate leakage, no credential sharing) and sanctions / export-control obligations under §22 survive termination indefinitely as to any data received during an active subscription.

5.4 API access.Buyers receive a single unified API key. Usage is subject to the rate limits published in the Platform's API documentation; those limits may change with reasonable notice. Breach of rate limits or of §5.1 may result in immediate suspension of API access. Beyond rate limits, the following are expressly prohibited: automated extraction, scraping, crawling, headless browsing, or systematic downloading of Platform content by any means, regardless of whether such activity remains within published rate limits. The API, as documented, is the only sanctioned machine-readable channel for Feed data; all other channels are for human interactive use only.

5.5 Scope of filters and displayed fields.Subscriptions are priced and delivered based on the date range of records included. Other filters visible on Feed listings (such as commodity or vessel type) are descriptive metadata about the Feed's typical content and are not contractually enforced per record. Buyers should rely on the API schema and date range for what they are entitled to receive.

5.6 Data export. Buyers are expected to export historical data via the API during the active subscription. Signal makes no commitment to provide data exports after cancellation.

5.7 Data verification and acknowledgement.You acknowledge that Feed data is provided on an "as-is" basis per §4.9 and that maritime lineup data is inherently uncertain, subject to change, and dependent on third-party sources. You are solely responsible for independently verifying any data before relying on it for commercial, operational, trading, chartering, insurance, or other business decisions. You assume all risk of loss, damage, or consequence arising from use of the data.

6. Buyer Registration & Vetting

6.1 Vetting criteria.Buyer registrations are subject to Signal's vetting. Signal may decline or later suspend any registration for reasons including, but not limited to:

• (a) the Buyer is a competitor of Signal Group (including the PortSignal marketplace, Signal Ocean platform, and Signal Maritime);
• (b)the Buyer is a direct competitor of a Contributor whose Feed it seeks to subscribe to (Signal's discretion).

6.2 Sanctions and export control. Buyer warrants, at registration and on a continuing basis, that it is not subject to and not owned or controlled by a person subject to applicable sanctions or export-control laws and regulations, including those administered by OFAC, the EU, the UK, and the UN, and that it will not use Feed data in breach of any such laws. Signal performs sanctions screening at registration and on an ongoing basis.

6.3 Ongoing non-competitor warranty.Buyer warrants continuously that it has not become a Signal Group competitor. On any material change — acquisition, merger, launch of a competing business — Buyer must notify Signal within 30 days. Signal may terminate all of that Buyer's subscriptions without refund.

6.4 Use-case attestation. Buyer declares its intended use at signup. Illustrative permitted use cases include chartering and trading desks, insurance underwriting, hedge funds conducting market research and analysis, ports performing market analysis, and physical commodity traders identifying market players and flows. Material deviation from the declared use without notice is a breach.

6.5 Restricted-use sectors.Journalism and media publication, and government, intelligence, or defence use, require Signal's prior written approval. Reselling, redistribution, and sublicensing are absolutely prohibited (§5.1) and no approval path exists for them.

6.6 Re-registration after suspension.A Buyer whose account has been suspended or terminated (or any affiliated entity) may register again only with mandatory disclosure of the prior account and Signal's re-running of vetting. Failure to disclose results in immediate re-suspension.

6.7 Review of adverse decisions. A Buyer whose registration is declined may request a review by emailing portmarketplace@portsignal.com. Signal will respond within 10 business days.

7. Payments, Tax, Invoicing

7.1 Currency and pricing. Prices are in USD.

7.2 Tax.Prices are exclusive of applicable taxes. VAT, sales tax, and other indirect taxes are added at checkout based on the Buyer's location and any tax identification provided. VAT identification numbers and billing addresses are collected at checkout.

7.3 Payment processing. Buyer payments are processed via Stripe. Signal does not store full card numbers.

7.4 Late payment.On a failed payment: (a) API access is revoked immediately; (b) the Buyer has a 7-day grace period to cure; (c) on day 8 the account is fully suspended if still unpaid; (d) overdue sums bear interest at 2% per month (or the maximum permitted by applicable law, if lower); (e) Buyer is liable for Signal's reasonable collection costs, including legal, collection-agency, and court fees.

7.5 Chargebacks.If a Buyer wins a Stripe chargeback after Signal has paid the Contributor the corresponding payout: (a) Signal may claw back the disputed payout from the Contributor's next payouts; (b) Buyer is liable for Signal's chargeback processing fee (currently ~USD 25) and may be suspended pending resolution; (c) if the chargeback is fraudulent or in bad faith, §14 Liquidated Damages may apply.

7.6 Currency changes. Signal may add additional currencies in future versions. Any change to currency handling will be notified in advance.

8. Prohibited Conduct

You must not:

• publish data you do not have the legal right to sell (§4.1);
• create fake, fraudulent, or misleading Feeds;
• attempt to circumvent the Platform to establish direct Buyer–Contributor relationships (see also §15);
• redistribute, resell, or sublicense Feed data (§5.1);
• use automated tools to scrape, crawl, or bulk-download Platform content regardless of rate limits (§5.4);
• use shared, pooled, or multi-tenant accounts to extend data access beyond your permitted corporate group;
• register under false identity or false affiliation, including to bypass vetting;
• attempt to identify any Anonymous Contributor;
• use Feed data in breach of sanctions or export-control law;
• interfere with Platform security, availability, or other users' use.

9. Intellectual Property

9.1 Platform, code, and Reference Data.The Platform, its code, design, and all Signal Reference Data (vessel database, commodity tree, port database, benchmark data) are Signal's intellectual property. Signal warrants that the Reference Data is Signal-owned and is not subject to third-party licence terms that would require flow-through to users.

9.2 Raw Contributor data.Raw lineup data contributed by a Contributor remains the Contributor's property, subject to the distribution licence in §4.3.

9.3 Feed Output (delivered normalised data).The Feed Output combines Contributor raw data with Signal's normalisation and Reference Data. Neither party may lift the Feed Output and redistribute it: Contributors may withdraw their raw data, but the normalised output itself may not be republished elsewhere; Buyers are subject to §5.1.

9.4 AI-generated content.Any output generated by Signal's AI tooling — including suggested pricing, normalised extracted data, automated summaries, support replies, or other machine-generated content — is Signal's intellectual property. Contributors and Buyers receive a licence to use such output solely through the Platform and within the scope of their subscription or contribution.

9.5 Trademarks.The "PortSignal" name, logos, and associated brand marks are Signal's property. Buyers and Contributors may make factual reference to their use of the Platform (e.g. "we subscribe to PortSignal"); Signal may similarly make factual reference to Buyers and Contributors as customers. Use of logos, testimonials, case studies, or other promotional materials requires prior written consent from the other party. Anonymous Contributors' identities are never used regardless of consent.

9.6 Feedback and suggestions. Any feedback, feature request, bug report, or suggestion you provide to Signal is granted to Signal under a perpetual, royalty-free, worldwide licence for any purpose. You retain any moral rights you have; Signal may use your feedback without obligation to attribute or compensate.

9.7 Platform transformation of Contributor data.Signal performs platform-defined data transformation on Contributor-submitted lineup records, including deduplication of near-duplicate submissions across recurring circulars, cross-circular merging of records describing the same vessel call, cross-source enrichment of blank fields from sibling submissions, and conflict resolution between sources reporting divergent values. The merged output returned by the Buyer API and surfaced in the Marketplace is a derivative work produced by Signal's platform, composed from one or more Contributors' feeds according to platform-defined rules. Contributors retain rights to their contributed raw data as set out in §9.2 and acknowledge that merged or otherwise derived outputs are platform-produced compositions under §9.3. Buyers access this transformed output under their subscription and remain subject to the redistribution limits in §5.1.

10. Confidentiality

10.1 Marketplace confidentiality.Buyers treat as confidential information of Signal and/or the Contributor: marketplace listings, Feed pricing, Contributor identities (where named), Feed metadata, rating information, and any other information made available through the gated marketplace. Buyers may use such information solely for their own internal decision-making in connection with their subscription. Breach is grounds for suspension and damages under §14. This obligation survives termination indefinitely.

10.2 Signal's reciprocal confidentiality. Signal treats user account information as confidential and only discloses it (a) to process the service, (b) to comply with legal obligations, or (c) as otherwise permitted by the Privacy Policy.

11. Disclaimers & Limitation of Liability

11.1 "As-is".The Platform and all data made available through it are provided on an "as-is" and "as-available" basis. Signal uses commercially reasonable endeavours to make the Platform available 24/7, subject to planned maintenance (performed outside normal business hours with advance notice where possible), third-party infrastructure failures, and events of force majeure. No guaranteed uptime percentage is offered.

11.2 Disclaimed damages. To the maximum extent permitted by law, Signal is not liable for any: indirect, consequential, incidental, special, punitive, or exemplary damages; lost profits; lost revenue; lost business; lost data; business interruption; loss of goodwill; damages arising from erroneous research, analysis, or decisions; force majeure events; third-party infrastructure failures or cyberattacks; acts or omissions of third parties.

11.3 Residual liability cap.Subject to §11.4, Signal's total aggregate liability to any single claimant, regardless of form of action, is limited to the lower of (a) USD 1,000, or (b) the claimant's single lowest monthly subscription fee paid to Signal (where applicable). Where the claimant has not paid any subscription fee to Signal (for example, a Data Contributor or a trial-only Buyer), the cap is USD 1,000.

11.4 Carve-outs (liability not excluded).Nothing in these Terms excludes or limits liability for: (i) death or personal injury caused by Signal's negligence; (ii) fraud or fraudulent misrepresentation by Signal; (iii) any liability that cannot lawfully be excluded or limited.

11.5 Beta features. Features labelled Beta, Preview, or Experimental are provided without warranty, SLA, or service credits, and may be changed or removed at any time without notice. Availability of such features does not extend the warranties or commitments that apply to GA features.

12. Indemnification

12.1 Buyer indemnity.Buyer shall defend, indemnify, and hold harmless Signal, its affiliates, officers, employees, and Data Contributors whose Feeds Buyer has accessed ("Indemnified Parties") from and against any third-party claims, demands, proceedings, losses, damages, liabilities, settlements, judgments, regulatory fines, and reasonable legal fees arising out of or related to:

• (a)any redistribution, resale, sublicensing, publication, or sharing of Feed data outside Buyer's permitted corporate group, in breach of §5.1;
• (b) any unauthorised disclosure of Feed data, including via shared API credentials, screen captures, data exports shared externally, or derivative products built on Feed data and made available to third parties;
• (c) use of Feed data in violation of applicable law, including sanctions, competition law, or data-protection law;
• (d)breach of §5, §6, or §8;
• (e)any claim by Buyer's affiliate, employee, contractor, customer, or external consultant arising from Buyer's use (or misuse) of Feed data;
• (f)attempts to circumvent the Platform to contract directly with a Contributor first discovered through PortSignal (see §15).

12.2 Contributor indemnity. Contributor shall defend, indemnify, and hold harmless Signal and its affiliates from and against any claims arising out of or related to:

• (a)breach of the Contributor's warranty in §4.1;
• (b) any third-party claim that the contributed data infringes intellectual property, violates confidentiality obligations, or breaches any contract binding on Contributor;
• (c)claims brought by Contributor's former or direct clients (for example, a port-agent's client alleging their data was routed through PortSignal without consent);
• (d) fraud, willful misconduct, or publishing data Contributor knows to be fabricated or unlawfully obtained.

12.3 No Signal indemnity between users.Signal does not indemnify Buyers against Contributors or Contributors against Buyers. Signal acts as a marketplace intermediary. Data-quality risk is allocated by §4.9; data-rights risk is allocated by §4.1 and §12.2.

12.4 Procedure.The Indemnified Party will (a) promptly notify the indemnifying party in writing, (b) give the indemnifying party sole control of the defence and settlement (provided no settlement admits liability or imposes obligations on the Indemnified Party without its written consent), and (c) reasonably cooperate at the indemnifying party's expense. Failure to notify promptly only reduces the indemnity to the extent of material prejudice.

12.5 Contributors as third-party beneficiaries.Contributors are expressly named as third-party beneficiaries of §12.1 and §14 and may enforce those provisions directly against the Buyer, whether or not Signal elects to do so. This is the sole circumstance in which a Contributor has direct contractual rights against a Buyer under these Terms.

13. Audit & Monitoring

13.1 Access-pattern monitoring.Signal monitors access patterns (API usage, login IPs, magic-link IPs, concurrent sessions) for security and anti-sharing enforcement. Such monitoring is not used for advertising or commercial profiling. Suspicious patterns may trigger automated rate-limiting, suspension, or an audit request under §13.2.

13.2 Audit right.Signal may, on 30 days' written notice, not more than once in any 12-month period, and at Signal's expense, audit a Buyer's access logs and usage records to verify compliance with §5.1. If breach is found, Buyer bears the reasonable audit costs plus any damages under §12 or §14. The audit scope is limited to records relating to Feed data access and sharing.

14. Non-Circumvention and Liquidated Damages

14.1 Non-circumvention.For a period of 24 months after the Buyer's last active subscription, the Buyer shall not directly contract with any Contributor first discovered through the Platform, other than through the Platform. Breach entitles Signal to recover the commission that would have been earned during the circumvented engagement.

14.2 Liquidated damages for §5.1 breach.The parties acknowledge that damages for breach of §5.1 (redistribution, resale, sublicensing, credential sharing, attempted de-anonymisation, affiliate leakage) are difficult to quantify. The parties agree that 24 months of the Buyer's fees on the affected Feed(s), with a floor of USD 25,000 per Feed per breach, is a genuine pre-estimate of loss and shall be payable as liquidated damages. Contributors may enforce this clause directly as third-party beneficiaries under §12.5.

15. Duty to Report Misuse

Both Buyers and Contributors must notify Signal in writing within 10 business days of becoming aware of suspected misuse of the Platform or Feed data — for example, a Contributor spotting their data offered for sale elsewhere, or a Buyer observing credential sharing or unauthorised access by another party. Reports should be sent to the contact addresses in §24. Good-faith reporters are indemnified by Signal against retaliation by the party in breach.

16. Account Deletion & Termination

16.1 Voluntary deletion.Any user may delete their account through account settings. Deletion is processed within 24 hours.

16.2 Contributor deletion. When a Contributor deletes their account: all published Feeds are archived immediately; no new subscriptions or trials are accepted; existing Buyer subscriptions are cancelled and billing stops immediately (no further charges); Buyers retain read-only access to the data as it existed at deletion for a 90-day grace period, after which access is revoked. No pro-rata refunds to Buyers for paid but unused days. Pending Contributor payouts for already-completed billing periods are processed normally.

16.3 Buyer deletion. When a Buyer deletes their account, all active subscriptions are suspended and billing is frozen immediately; API access is revoked.

16.4 Feed discontinuation risk.Feeds may cease updates due to Contributor deletion, archival, or other circumstances. Subscriptions are billed in advance; no prorated refund is issued for the remainder of a billing period in which a Feed stops updating. By subscribing, Buyers acknowledge this risk (see also §5.3, §11).

16.5 Termination for cause (Signal-initiated).Signal may suspend or terminate a user's account immediately and without refund upon:

• (a)breach of §5.1;
• (b) a failed sanctions or export-control screen;
• (c)the Buyer becoming a Signal Group competitor (breach of §6.3);
• (d) non-payment or failed chargeback.

Suspension is typically the first-line response; termination follows if the breach is not or cannot be cured.

16.6 Re-registration.See §6.6.

17. Data Retention

• Lineup records.Signal retains lineup records indefinitely for audit, legal, and tax purposes. No user-initiated purge right applies against Signal's audit copies, save as described in §5.2.1 in respect of trial-only data.
• Deactivated user profiles. Archived for 5 years following account deletion, then permanently deleted.
• Banking and payment details. Signal does not retain full card or bank numbers; Stripe retains payment records subject to its own data-retention policy.
• Contact details.Name, email, and phone are anonymised (replaced with nulls or hashes) 30 days after account deletion, except where retention is required for an ongoing billing dispute, tax, or other legal obligation.
• Subscription and commission history. Retained for 7 years to meet tax and legal obligations.

18. Platform Changes

Signal may iterate on Platform features at any time. Material adverse changes to paid features will be communicated with reasonable advance notice (target: 30 days). Minor changes may be made without notice. Beta features are subject to §11.5.

For API versioning, Signal provides 6 months' advance notice before deprecating a major API version; future major versions will have a parallel-run period during that window.

19. Force Majeure

Neither party is liable for failure or delay in performance arising from events beyond its reasonable control, including: war, terrorism, civil unrest, natural disasters (earthquake, flood, storm), pandemic or epidemic, power, internet, or cloud-provider outages (including Vercel, Stripe, Clerk, Supabase, Upstash, Anthropic), cyberattacks or denial-of-service events, government action or sanctions, and strikes or labour disputes. The affected party must notify the other without undue delay.

20. Anti-Bribery

Each party complies with the UK Bribery Act 2010, the US Foreign Corrupt Practices Act, and equivalent anti-bribery and anti-corruption laws. Neither party offers, gives, solicits, or accepts any bribe, kickback, or improper advantage in connection with the Platform. Breach entitles the other party to immediate termination.

21. Assignment

Signal may assign these Terms in whole or in part, including to an affiliate or to a successor in connection with a corporate transaction, without consent. Users may not assign without Signal's prior written consent. Any purported assignment in breach of this §21 is void.

22. Sanctions & Export Control

In addition to §6.2, all users warrant that their use of the Platform and any Feed data will comply with applicable sanctions and export-control laws, including those administered by OFAC, the EU, the UK, and the UN.

23. Dispute Resolution

23.1 Informal resolution.Before commencing formal proceedings, the parties shall attempt in good faith to resolve any dispute through direct discussions for a period of 30 days after one party notifies the other in writing. This requirement does not apply to claims for injunctive relief (for example, IP or §5.1 breaches).

23.2 Governing law. These Terms are governed by the laws of England and Wales.

23.3 Exclusive jurisdiction.Each party submits to the exclusive jurisdiction of the courts of England and Wales sitting in London, save where mandatory consumer-protection law of the Buyer's residence provides otherwise.

24. Notices

24.1 Email as binding channel. Email is the binding notice channel for all purposes, including legal notices.

24.2 Signal's service addresses.

• Privacy and data-protection matters: privacy@thesignalgroup.com
• Platform, commercial, and general: portmarketplace@portsignal.com

24.3 User's service address. The email address on your account. You must keep it current.

24.4 Deemed receipt.Notices are deemed received on the day of transmission if sent during the recipient's local business hours, otherwise on the next business day.

25. Changes to These Terms

Signal may update these Terms. For material changes, Signal will notify users by email and on the Platform at least 30 days before the effective date.
