Terms of Service

By accessing or using Prior.Run (“the Service”), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

Prior.Run is a pre-launch design validation platform. You upload one design or compare two variants, and our system produces a structured decision memo that shows what to ship, what to fix, and where risk lives — including friction analysis, audience reactions, and compliance flags.

Our Content

• Prior.Run owns the analysis output format, methodology, interface design, and underlying technology.
• You may use analysis results for your internal business purposes, share memos via our sharing feature, and reference insights in your decision-making.
• You may not resell, redistribute, or white-label analysis outputs as a competing service.

• Prior.Run provides design analysis as a decision-support tool. We do not guarantee that our predictions will match real-world A/B test outcomes.
• The Service is provided “as is” and “as available” without warranties of any kind, express or implied.
• In no event shall Prior.Run be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or business opportunities.
• Our total liability shall not exceed the amount you paid us in the twelve months preceding the claim.

• By you: You may close your account at any time by contacting us. Upon closure, your data will be deleted within 30 days.
• By us: We may suspend or terminate your account if you violate these Terms, engage in abusive behavior, or fail to pay for a Pro subscription.
• Upon termination, your right to use the Service ceases immediately. We may retain anonymized, aggregated data for analytics purposes.

We may update these Terms from time to time. We will notify registered users of material changes via email at least 14 days before they take effect. Continued use of the Service after changes become effective constitutes acceptance of the updated Terms. If you disagree with the changes, you should stop using the Service and close your account.

These Terms shall be governed by and construed in accordance with the laws of the United States. Any disputes shall be resolved through good-faith negotiation first, and if necessary, binding arbitration.
