Terms of Use

These Terms govern use of Certaffy websites and products. By creating an account or using the service, you agree to these Terms.

Last updated: July 17, 2026

The service

Certaffy provides probabilistic AI-writing review and related tools. Scores and highlights are review aids, not definitive proof of authorship or misconduct.

You are responsible for how you use results, including compliance with your institution’s or organization’s policies.

Accounts and plans

Some features require a paid plan (for example PDF report downloads, passage explanations, and AI paraphrase risk). Plan limits and features are described on Pricing and enforced in the product.

You must provide accurate account information and keep credentials secure. Do not share accounts in ways that violate your plan or these Terms.

Acceptable use

Do not misuse the service to harass, unlawfully process personal data, reverse engineer the product beyond applicable law, or attempt to bypass security or plan limits.

Uploaded content must be material you are authorized to submit for review.

Disclaimers

The service is provided as-is within the limits of applicable law. Detection may produce false positives or false negatives. Do not rely on a single score as the sole basis for adverse action.

We may update these Terms; material changes will be reflected by the last-updated date on this page.
