CHECKBOOTH — BETA TERMS OF USE & PRIVACY NOTICE (v1.1-beta)
Effective Date: November 2026 · Operator: Wesley Covert ("Operator", "we", "us") · Contact: the contact form at /contact
1. Electronic Transactions & Electronic Agents (Cal. Civ. Code §§ 1633.5, 1633.14).
You must be at least 18 years old to use this website, API, or Model Context Protocol (MCP) server ("Service"). You agree to conduct transactions with us electronically. Under California Civil Code § 1633.14, an agreement may be formed through the actions of an electronic agent you deploy or fund, even if no individual reviewed these Terms or the output at the time. When paid service begins, these Terms will be updated to name the operating company, and you'll be asked to accept them again.
2. Nature of Service — Planning & Math Check Only (Rule G).Planning and math verification check only — not a licensed professional engineering review, stamp, or sign-off. We do not offer or provide licensed professional engineering services, architectural services, safety certifications, code approvals, or physical inspections. The Service performs automated mathematical recomputation solely on numbers you supply. Only items marked "Checked & Acceptable" or "PASS" passed our local recomputation, and only for the numeric inputs you supplied; nothing is checked against the physical world. If optional third-party AI tools (Path B) are enabled in a future release, their outputs are produced by automated software, including third-party AI models, and may be incomplete or wrong. You and your agent decide what to do with an output and are solely responsible for independent verification before relying on any result.
3. Prohibited Uses & Restricted Data (Rules H & I).
You must not submit:
(a) Export-Controlled or Classified Data: Any technical data subject to ITAR (22 CFR Parts 120–130), EAR (15 CFR Parts 730–774), Controlled Unclassified Information (CUI), or classified material.
(b) Life-Safety & Critical Systems: Any use for life-safety, medical-device, patient-dosing, aviation, nuclear, weapons, automotive-safety, or structural sign-off applications.
(c) Employer or Jobsite Data: Any data from your employer or its job sites, ever, or any confidential third-party data.
We may refuse, suspend, or delete any request we believe falls in these categories. You agree to indemnify and hold Operator harmless from any claim, loss, or regulatory penalty arising out of your breach of this Section 3.
4. Free Proof-of-Concept Beta & Future Origin Credits (Rule B).
Free 2026 Beta Rules: During the 2026 proof-of-concept beta, only deterministic local tools (Path A) are active, no reservations are charged, and no paid sale happens in 2026. The free beta may change, be rate-limited, or stop at any time without notice; there is no uptime commitment, and we may revoke sandbox keys at any time.
Future Paid Service & Origin Credits: Requests may be used to build new tools. Once paid service launches under the operating company, if your request leads to a new tool that others use, you earn Origin Credits: 15% of what distinct paying callers pay to run it (posted in hundredths of a credit after a 7-day hold), as non-cash credits for future runs. Credits have no cash value, can't be transferred or withdrawn, are not earned on self-runs, shared-card/wallet accounts, runs paid with free credits, or refunded/disputed payments, and the program can change with 30 days' notice without reducing credits already earned. Larger credit or revenue sharing beyond this is at our discretion and is owed only if offered in writing.
5. Disclaimer of Warranties & Limitation of Liability (Cal. Civ. Code § 1668).
THE SERVICE AND ALL OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW (AND EXCLUDING ONLY LIABILITY THAT CANNOT BE LIMITED UNDER CALIFORNIA CIVIL CODE § 1668), OPERATOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR LOST-PROFIT DAMAGES, AND OPERATOR'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR ANY OUTPUT SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE, OR (B) FIFTY U.S. DOLLARS ($50.00 USD).
6. Governing Law, 60-Day Notice & Sacramento County Venue.
These Terms are governed by California law. Before filing any legal claim, you must send a written Notice of Dispute through the contact form at /contact and allow 60 days to resolve it informally. Any unresolved dispute within small-claims jurisdiction may be brought in Small Claims Court in Sacramento County, California; otherwise, the state and federal courts located in Sacramento County, California shall have exclusive jurisdiction and venue.
7. Privacy Notice.
What We Process & Store: During the Path A proof-of-concept beta (discover_capabilities, explain_chain, verify_math_or_tolerance, run_slice_chain, verify_report_receipt, and /check), all calculations run locally on our server with no third-party AI model calls and no file uploads. We store SHA-256 hashes of API keys, hmac(IP + user agent) values for rate-limiting and second-party handoff verification counts, and run/ticket records for up to 30 days. The compact receipt header kept permanently for /check?report= verification includes no prompt text or raw inputs—only cryptographic hashes, the verdict summary, the timestamp, and the Ed25519 signature.
Booth Accounts & Contact Form: If you open a booth, we store the SHA-256 hash of your account key and of the invite code you used, and the booth name, web address, checks and prices you set; booth pages are public. If you use the contact form, we keep your message and any reply address you give for up to 30 days.
Service Providers (Processors): We use Render (application hosting). When a domain is connected we will add Cloudflare (DNS and email routing). When paid service launches in 2027, Stripe will process payments (we never see or store full card numbers) and optional Path B tools will route inputs to disclosed AI model providers (xAI and OpenRouter).
Data Deletion: We never sell your data. Use the contact form at /contact with your sandbox key prefix or ticket ID to delete any optional contact email or unpurged 30-day records.
8. Member Booths.
User-configured booths and chains are created by their respective account holders, not Operator; you may not use any booth name or label that implies professional licensure, certification, or affiliation, and we may unpublish or remove any booth, chain, or key at any time for any reason.
