Terms of Service

Last updated: July 28, 2026

These Terms of Service (the “Terms”) are an agreement between you and Tensorheart, Inc., a Delaware corporation with its principal place of business in San Francisco, California (“Tensorheart”, “we”, or “us”). They govern the Stetworth service, including this site, the waitlist, and the application (together, the “Service”). Please read them — the arbitration agreement in Section 13 affects how disputes between you and Tensorheart are resolved.

1. Acceptance of these Terms

By accessing or using the Service — including browsing this site or joining the waitlist — you accept these Terms. If you use the Service on behalf of a company or firm, you accept these Terms for that organization as well, and you represent that you are authorized to do so. If you do not agree to these Terms, do not use the Service.

2. Eligibility and business use

The Service is offered for business and professional use, not for personal, family, or household purposes. You must be at least 18 years old and able to form a binding contract to use the Service.

3. Accounts and access

New accounts open in batches. Whether, when, and in what order access is granted is at Tensorheart’s sole discretion; a place on the waitlist is not a promise of access.

You are responsible for your account: keep your credentials confidential, make sure the information you give us is accurate, and tell us promptly at [email protected] if you suspect unauthorized use. Activity under your account is treated as yours.

4. The Service may change

Tensorheart may add to, change, suspend, or discontinue any part of the Service — or the Service as a whole — at any time, with or without notice. Deliverables the Service produces are prepared for your review; you are responsible for reviewing, approving, and deciding how to use them.

5. Customer content

Content you submit to the Service — files, instructions, criteria, and similar material (“Customer Content”) — remains yours. You grant Tensorheart a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, transmit, and display Customer Content as reasonably necessary to provide, maintain, secure, and improve the Service. You represent that you have all rights needed to submit Customer Content and to grant this license.

6. Feedback

If you send Tensorheart suggestions, ideas, or other feedback about the Service, you assign to Tensorheart all right, title, and interest in that feedback, and Tensorheart may use it for any purpose without restriction or compensation.

7. Acceptable use

You agree not to:

  • use the Service in violation of law, or to infringe or misappropriate anyone’s rights;
  • submit content you do not have the right to submit;
  • probe, disrupt, or overload the Service, or bypass its access controls or approval gates;
  • reverse engineer the Service, except where law forbids that restriction;
  • resell access to the Service, or use the Service to build a competing product or service;
  • misrepresent who you are or who you work for, including during verification.

8. Third-party services

The Service works with third-party services — LinkedIn for verification, and the tools you choose to connect. Those services belong to their providers and are governed by their own terms. Tensorheart is not responsible for third-party services and makes no promises about them.

9. Disclaimer of warranties

THE SERVICE AND ALL OUTPUT OF THE SERVICE ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, TENSORHEART DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. TENSORHEART DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY OUTPUT WILL BE ACCURATE, COMPLETE, OR FIT FOR YOUR PURPOSES.

10. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, TENSORHEART WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUES, DATA, OR GOODWILL, UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TENSORHEART’S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS IS LIMITED TO THE GREATER OF ONE HUNDRED U.S. DOLLARS ($100) OR THE FEES YOU PAID TENSORHEART FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM.

11. Indemnification

You will defend, indemnify, and hold harmless Tensorheart and its officers, directors, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of Customer Content, your use of the Service, or your breach of these Terms.

12. Governing law

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws principles. The Federal Arbitration Act governs Section 13.

13. Dispute resolution and arbitration

Any dispute arising out of or relating to these Terms or the Service will be resolved by binding arbitration on an individual basis, administered by JAMS in San Francisco, California under the JAMS rules then in effect. You and Tensorheart each waive the right to a trial by jury and the right to participate in a class, collective, or representative action.

Two carve-outs: either party may bring an individual claim in small-claims court, and either party may seek injunctive or other equitable relief in a court of competent jurisdiction to protect its intellectual property or to prevent unauthorized access to the Service.

14. Changes to these Terms

Tensorheart may amend these Terms by posting the revised version on this page and updating the “Last updated” date above. Changes take effect when posted. Using the Service after a change is posted means you accept the revised Terms.

15. Termination

You may stop using the Service at any time. Tensorheart may suspend or terminate your access to the Service at any time, with or without cause or notice. Sections that by their nature should survive termination — including Sections 5, 6, and 9 through 13 — survive.

16. Severability and entire agreement

If any provision of these Terms is held unenforceable, the rest remain in full effect. Tensorheart’s not enforcing a provision is not a waiver of the right to enforce that provision later. You may not assign these Terms without Tensorheart’s consent; Tensorheart may assign them in connection with a merger, acquisition, or sale of assets. These Terms are the entire agreement between you and Tensorheart about the Service and supersede any prior agreements on that subject.
