By accessing x401.id (“Website”), you agree to these Terms of Use (“Terms”) on behalf of yourself and anyone accessing the Website through your connection.

Changes are effective when posted, as indicated by the “Last Modified” date above.

2. Open Source Protocol

The identity verification protocol described on this Website is separate from the Website itself. The protocol is available as open source software via the GitHub repository linked on this Website and is governed solely by the applicable open source license, not these Terms. The Company makes no representations or warranties regarding the protocol or open source software and, to the fullest extent permitted by law, disclaims all liability arising from it; your use of the protocol is at your own risk and subject to the applicable open source license. Contributions to the protocol are made through the GitHub repository and are governed by its applicable open source license and any contributor agreement or contribution guidelines posted there, not by these Terms.

3. Intellectual Property

The text, graphics, and design of this Website are owned by the Company or its licensors and protected by applicable intellectual property law. This Section covers the Website only; it does not apply to the x401 protocol or its specification, which are open and addressed in Section 2.

You may use the Website for personal, non-commercial, internal business, educational, and research purposes. Permitted uses include: temporary RAM copies incidental to access; browser caching; and printing or downloading a reasonable number of pages for those purposes. You may not reproduce, distribute, modify, or commercially exploit Website content, or remove any proprietary notices. For any use not expressly permitted here, contact legal@proof.com.

You may use the “x401” and “Proof” names to identify, describe, discuss, implement, or report on the protocol and the Website, without prior permission. You may not use the Company's logos, or use any name or mark in a way that suggests an endorsement, sponsorship, or affiliation that does not exist. Nothing in these Terms restricts the open use, implementation, or discussion of the protocol.

4. Prohibited Conduct

You may not use the Website to:

  • violate any applicable law or regulation;
  • exploit or harm minors;

You may link to this Website provided you do so fairly and without implying any form of association or endorsement by the Company.

7. Privacy

This Website does not require account creation or submission of personal information. Standard server logs (e.g., IP address, browser type) may be collected for security and operational purposes. Depending on your jurisdiction, this log data may be considered personal information. A Privacy Policy will be posted if the Website begins collecting additional personal information.

THIS WEBSITE IS PROVIDED FREE OF CHARGE. TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY’S TOTAL LIABILITY FOR ANY CLAIM ARISING FROM YOUR USE OF THE WEBSITE SHALL NOT EXCEED $100. THE COMPANY WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, REVENUES, OR DATA, ARISING FROM OR RELATING TO THE WEBSITE, WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY. THESE LIMITATIONS DO NOT APPLY TO LIABILITY ARISING FROM THE COMPANY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, OR TO LIABILITY THAT CANNOT BE EXCLUDED BY APPLICABLE LAW.

11. Indemnification

You agree to defend, indemnify, and hold harmless the Company and its affiliates, officers, directors, employees, and agents from any claims, losses, costs, and expenses (including reasonable attorneys’ fees) arising from your violation of these Terms or your misuse of the Website.

12. General

These Terms are governed by the laws of the State of Delaware (without regard to conflict-of-law rules). Any dispute arising from these Terms or use of the Website shall be resolved by final and binding arbitration under AAA Rules applying Delaware law; either party may seek injunctive or other equitable relief in any court of competent jurisdiction to protect intellectual property rights. All disputes will be resolved on an individual basis only; you and the Company waive any right to bring or participate in a class, collective, consolidated, or representative action. Any claim must be brought within one (1) year after it accrues; otherwise it is permanently barred. If any provision of these Terms is held unenforceable, the remaining provisions continue in full force. These Terms constitute the entire agreement between you and the Company regarding the Website and supersede all prior agreements.
