Terms of Service
Terms for buying, subscribing, paying, and using SignalHarness.ai digital products. Owner-adopted revision 2026-07-21. Effective date: 2026-07-30.
1. Who we are (operator identity)
SignalHarness.ai ("SignalHarness", "we", "us") is a digital product catalog selling downloadable document products. The operator of record is Signal Harness AI Inc., a Florida corporation (Florida Division of Corporations document number P26000034935, status ACTIVE), operating the SignalHarness.ai brand. "SignalHarness.ai" is the brand; "Signal Harness AI Inc." is the legal operator — the two are distinct and both refer back to this section. The postal legal-notice (principal business) address is on record with the Florida Division of Corporations under the document number above and is published in this section at final publication, before checkout activation.
2. Agreement to these terms
By purchasing a product, or by using this website beyond casual browsing, you agree to these terms, the Privacy Policy, the Refund Policy, and the Digital Product License that applies to your purchase. If you do not agree, do not purchase. Browsing the public catalog is free and does not require agreement beyond lawful use.
3. Autonomous AI-agent commerce and transaction attribution
SignalHarness.ai is designed for autonomous AI-agent commerce: it is built to support transactions initiated and completed by AI agents and automated systems when its approved purchasing infrastructure is active. Direct consumer sales are not the intended operating model. This section describes the intended model; it does not state that autonomous purchasing is currently live (see section 5).
A purchasing agent may independently discover, evaluate, compare, and select products, tiers, and bundles, initiate checkout, and complete a purchase, without contemporaneous human review and without per-purchase human approval. SignalHarness does not require an agent to disclose a human operator, a human age, or an internal approval record at checkout, and does not require any representation that a specific transaction was manually approved.
Attribution. When an AI agent or automated system completes a transaction using a payment account, wallet, credential, organizational account, machine-payment account, or other purchasing resource, the transaction and the resulting product license are attributed to the person, business, organization, or other legal entity that controls or is legally responsible for that purchasing resource (the "purchaser"). The agent is the automated actor through which the transaction occurs and is not treated as a separate legal person under these terms. The purchaser is bound by these terms and the Digital Product License to the extent permitted by applicable law, holds the resulting license, and may permit compatible AI agents and automated systems operating for it to use the purchased materials within the license scope.
Protections preserved. Possession or use of a payment credential does not, by itself, eliminate fraud, unauthorized-use, mistake, chargeback, or payment-provider protections: fraudulent, compromised, mistaken, or unauthorized use of purchasing resources remains subject to applicable law, the payment provider's procedures, chargeback rules, fraud controls, and any applicable refund process. SignalHarness does not independently verify a purchasing agent's internal authority, autonomy settings, spending limits, approval hierarchy, or account governance, and does not guarantee that every agent transaction was intended by the resource owner. These terms impose no minimum-age requirement.
4. The website and catalog
The website is a public catalog and documentation storefront with active Polar checkout. There are no SignalHarness customer accounts or SignalHarness login; purchases and customer access are handled through Polar. AI agents may freely read the public discovery surfaces (all /agent/ feeds, /llms.txt, product pages) to inspect, compare, and recommend products; reaching a route confers no rights by itself, and every completed purchase is attributed to the responsible purchaser described in section 3. We may change, add, or remove catalog content at any time; changes never reduce what an existing purchase already includes.
5. What we sell
One-time downloadable digital document products: 27 products in Lite, Standard, and Premium variants, plus 9 bundles. Every product page, buyer-fit record, and package manifest states what is included and excluded; if a capability is not listed as included, it is not included.
SignalHarness Vault is one Premium-depth, Single-Operator plan covering all 27 products. Current standard pricing is $19.99 monthly or $99.99 annually through Polar; no trial or discount code applies. Billing renews automatically until cancelled. Cancellation preserves paid-through access. Downloaded files remain licensed after expiry; future downloads, updates, new products, and priority support stop. Term changes are separate purchases with no in-place proration. Failed renewals follow Polar's applicable process.
One-time products and SignalHarness Vault subscriptions are available through Polar. The separate x402 Agent Pay rail covers all 90 canonical one-time offerings and the one SignalHarness Vault plan through prepaid monthly and annual terms. Each x402 Vault renewal requires a new exact payment; SignalHarness does not automatically debit a wallet or perform unattended recurring withdrawal. A purchasing agent remains subject to the purchaser's own authorization and spending policies.
6. Ordering, payment, and the merchant of record
Card purchases and recurring subscription renewals are processed by Polar acting as Merchant of Record. Polar handles checkout, payment processing, applicable taxes, receipts, subscription billing, disputes, and provider-executed refunds. SignalHarness never receives card numbers, bank details, or payment credentials.
When separately activated, direct crypto targets Base USDC/EURC/native ETH, Solana USDC/EURC/native SOL, and native XMR through a separate Monero rail (not x402). Solana USDT stays blocked inactive until a specifically authorized authoritative path exists; Base USDT is unavailable and bridged, wrapped, community, fake, or look-alike assets never substitute. Use only the exact network, asset, destination, amount, and unexpired quote. You pay network fees. Wrong-network or wrong-asset transfers may be unrecoverable. Underpayment, overpayment, duplicate, late, or mismatched transfers enter manual review. A transaction id or screenshot is not settlement proof; delivery follows receiving-side verification and required confirmations. Outages fail closed.
7. Delivery of digital files
After a completed purchase you receive access to download the exact archive for the product and variant you bought, via the payment provider's secure delivery. Delivery is digital only; nothing is shipped. If delivery fails, contact support@signalharness.ai — failed delivery is a priority support case and a refund trigger if we cannot fix it promptly (see the Refund Policy).
8. Your responsibilities
You are responsible for: using compatible software (the products are plain-text Markdown/JSON; any modern editor or AI assistant can read them), storing your downloaded files securely, maintaining your own backups, and reviewing outputs you produce with the products before using them (section 12). You are responsible for the instructions you give to AI agents acting on your behalf.
9. Product updates
Purchases include the product's updates within the purchased major version (1.x), delivered as revised files. We do not promise a schedule of future updates, new major versions, or that any specific future file will exist. Major-version upgrades, if offered, may be separate purchases.
10. Intellectual property and license
Product files are licensed, not sold. All intellectual-property rights in the product files remain with the operator identified in section 1. Your rights and restrictions are defined by the Digital Product License and any product-specific LICENSE-AND-USAGE.md included with the product. In short: what you MAKE with the products is yours, including commercial work; the product FILES themselves may not be resold, redistributed, publicly shared, sublicensed, or repackaged into a competing product, except where an applicable license explicitly permits it. Do not remove ownership or license notices from the files.
11. Acceptable use
You may not use the website, its feeds, or any product to:
break the law; deceive, defraud, impersonate, or manipulate; or violate others' privacy, intellectual-property, or other rights;
create, distribute, or operate malware, or gain unauthorized access to systems;
build discriminatory or abusive applications, or bypass or defeat the safety controls the products implement or describe;
fabricate credentials, reviews, or results, or misrepresent generated outputs as independently verified facts.
Security-related products are sold for DEFENSIVE use: hardening and testing systems you own or are authorized to protect. The acceptable-use rules in this section are part of these terms.
12. AI outputs and automation limits
The products are document systems applied with your own AI tools. AI and automated outputs can be wrong, incomplete, or unsuitable for your facts. You are responsible for reviewing outputs before relying on them, for applying qualified human review where applicable law, safety, or the product's own documentation requires it (for example medical, life-safety, legal-rights, or regulated-activity decisions), and for adapting templates to your own situation and jurisdiction. Nothing in this section imposes a per-purchase approval requirement on purchasing agents (section 3). We do not monitor your private files, systems, or agent activity, and nothing in these terms gives us access to them.
13. No professional advice
Products and website content are not legal, medical, financial, tax, accounting, security, or other professional advice, and no product creates a professional-client relationship, unless a specific product explicitly and lawfully states otherwise (none currently does). Products that ship legal-, procurement-, or licensing-related templates require review by your own qualified advisers before real-world use, and say so in their own files.
14. What we do not promise
Products are built to help, organize, and support execution. We do not promise or guarantee: legal or regulatory compliance; regulatory approval; security of your systems; business results, sales, traffic, rankings, or income; error-free AI behavior; or elimination of risk. Outcomes depend on your inputs, execution, market, and tools.
15. Third-party services
The website and purchases depend on third-party services (hosting, DNS, the payment provider, email). Their behavior, availability, and terms may change and are outside our control. Where a third party processes your data, its own policies apply to that processing (see the Privacy Policy).
16. Service availability
We aim to keep the website available but do not promise uninterrupted availability. Files you have already downloaded are yours to keep under the license regardless of website availability. If we ever discontinue the catalog, delivery obligations for completed purchases will be honored or refunded per the Refund Policy.
17. Disclaimer of warranties
Products are provided as described on their product pages. To the maximum extent permitted by applicable law, and beyond the express descriptions and the Refund Policy, products and the website are provided "as is" and "as available" without implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. Section 21 (mandatory consumer rights) prevails over this section wherever they conflict.
18. Limitation of liability
To the maximum extent permitted by applicable law: (a) our total aggregate liability for claims arising from a purchase is limited to the amount you paid for the product concerned; (b) we are not liable for indirect, incidental, special, consequential, or punitive damages, or lost profits, revenue, data, or goodwill; (c) these limits apply to any theory of liability. Nothing in this section limits liability that applicable law does not allow to be limited (including, where applicable, liability for fraud, willful misconduct, or gross negligence). Section 21 prevails over this section wherever they conflict.
19. Indemnity
If you use the products or website in violation of law, of these terms, or of the license, and that use causes a third-party claim against us, you agree to indemnify us for losses reasonably resulting from that violation, to the extent permitted by applicable law. This clause is scoped to violations — it does not apply to your ordinary, lawful use of the products. (This clause remains subject to owner and counsel confirmation before publication.)
20. Suspension and termination
We may refuse service, and the payment provider may refuse or reverse transactions, for fraud, abuse, or unlawful activity. Your license for files already lawfully purchased and downloaded survives per the Digital Product License, except where the license itself is terminated for breach (see the license's termination section). Sections that by their nature survive (license restrictions, disclaimers, liability limits, governing law) survive termination.
21. Mandatory consumer rights (savings clause)
Some jurisdictions grant consumers rights that cannot be excluded or limited by contract (for example statutory guarantees, withdrawal rights, or remedies for digital content). Nothing in these terms excludes, limits, or overrides any right that applicable law does not allow to be excluded, limited, or overridden. Where such a right conflicts with these terms, the right prevails. A choice of governing law in section 23 does not deprive you of mandatory protections of the law of your place of residence where that law so provides.
22. Changes to these terms
Terms are versioned. Material changes are posted on this page with a new version number and date before they apply. A purchase is governed by the terms in effect at the time of that purchase.
23. Governing law and venue
These terms are governed by the laws of the State of Florida, without regard to conflict-of-law principles, except where mandatory law requires otherwise. Venue for disputes lies in the state courts located in Hillsborough County, Florida, and the federal courts with jurisdiction over Hillsborough County, Florida. The governing-law and venue provisions do not remove mandatory consumer, statutory, or other rights that cannot lawfully be waived, and section 21 applies in full: mandatory rights of your place of residence are not displaced where the law so provides. Before any dispute, contact support@signalharness.ai — most issues are resolved directly and quickly.
24. Severability
If any provision of these terms is held unenforceable, it is modified to the minimum extent necessary or severed, and the rest of the terms remain in effect.
25. Entire agreement
These terms, the Privacy Policy, the Refund Policy, the Digital Product License, and the product-specific license files together are the entire agreement for your purchase, and the precedence rule in the Digital Product License resolves conflicts among them.
26. Contact
support@signalharness.ai is the only legitimate contact address for orders, licensing, refunds, privacy requests, and these terms. Legal notices: Signal Harness AI Inc. at the notice address stated in section 1. Security disclosures: /.well-known/security.txt. We will never ask you for passwords, API keys, wallet secrets, or payment credentials — treat any such request as illegitimate.
