Welcome to Proof ("Proof," "we," "our," or "us"), available at withproof.dev (the "Service"). These Terms of Service ("Terms") govern your access to and use of the Service.
By creating an account, submitting a URL, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.
Proof provides automated quality assurance testing for websites by running AI-powered persona simulations against user-submitted URLs. The Service may:
You must be legally able to enter into this agreement. You are responsible for all activity under your account and for maintaining account security.
You may submit a URL only if you have all necessary rights and permissions to authorize testing of that site or application.
By submitting any URL, you represent and warrant that:
You are solely responsible for obtaining and maintaining required permissions.
You agree not to use the Service to:
We may suspend or terminate access for suspected abuse, unauthorized testing, or policy violations.
To protect platform stability and prevent misuse, Proof enforces technical and policy limits.
Free Tier: currently limited to 1 run per email and 1 domain per day (or as otherwise displayed in-product).
Paid Plans: currently start at $29/month and are subject to plan-specific limits shown at purchase.
We may modify limits, queueing behavior, and usage controls at any time in our reasonable discretion.
To operate the Service, we process submitted URLs, run metadata, browser interaction data, screenshots, and generated reports. By using the Service, you authorize us to perform these actions for service delivery, safety, support, and improvement purposes as described in our Privacy Policy.
Reports and recommendations are generated in whole or in part using automated and AI-assisted systems. They may contain errors, omissions, false positives, or incomplete conclusions. You are responsible for independent verification before relying on any output.
The Service is not legal advice, security certification, or guaranteed compliance assurance.
Paid subscriptions are billed in advance on a recurring basis unless otherwise stated. Fees are non-refundable except where required by law or explicitly stated in writing. You authorize us and our payment processors to charge applicable fees, taxes, and renewal charges.
We retain all rights in the Service, software, and underlying technology. Subject to these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable right to use the Service.
As between you and Proof, you retain ownership of your submitted content. Subject to applicable law, you grant Proof a worldwide, non-exclusive license to host, process, and analyze submitted data for providing and improving the Service.
We will not publicly disclose your specific testing reports except (a) with your consent, (b) as required by law, or (c) in anonymized/aggregated form that does not identify you or your target properties.
We may suspend or terminate your access immediately if we reasonably believe:
You may stop using the Service at any time. Upon termination, licenses granted to you under these Terms end.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
We do not warrant uninterrupted availability, error-free operation, or that outputs will meet your requirements.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, PROOF AND ITS OWNER, OFFICERS, EMPLOYEES, CONTRACTORS, AND AFFILIATES WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) AMOUNTS YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE CLAIM OR (B) FIFTY U.S. DOLLARS (US $50).
Some jurisdictions do not allow certain limitations; in such cases, those limitations apply to the fullest extent permitted.
You agree to defend, indemnify, and hold harmless Proof and its personnel from claims, losses, liabilities, damages, costs, and expenses (including reasonable attorneys' fees) arising from or related to:
We may modify or discontinue features at any time. We may update these Terms from time to time. Continued use after the effective date of updated Terms constitutes acceptance.
These Terms are governed by the laws of the State of Oregon, without regard to conflict-of-law rules. You and Proof consent to exclusive jurisdiction and venue in the state or federal courts located in Multnomah County, Oregon, except where prohibited by law.
