Terms of Service

Last updated: August 1, 2026

1. Acceptance of Terms

By using EvidenceLens (the Service), including the website, browser extension, mobile app, and API, you agree to these Terms of Service. If you do not agree, do not use the Service.

2. Description of Service

EvidenceLens is a research-assistance product that analyzes YouTube videos, websites, and PDF documents to identify and verify factual claims against scientific literature. Results are provided for informational purposes only and should not be considered definitive scientific assessments.

3. Accounts and Authentication

You may use the extension without an account (Free tier). Creating an account via Google sign-in enables subscription management and activity tracking. You are responsible for maintaining the security of your account.

4. Subscription and Billing

  • The Free plan includes limited monthly usage at no cost.
  • The Plus monthly plan is billed at €5.99/month, and the Plus Lifetime plan is a one-time €49 payment via Stripe.
  • The Lifetime plan provides access to paid Plus features for as long as EvidenceLens continues to operate and offer those features. "Lifetime" means the lifetime of the EvidenceLens service, not the lifetime of any individual person or company. It does not guarantee that the Service, any specific feature, third-party integration, app distribution channel, data provider, or pricing package will remain available indefinitely.
  • Subject to applicable law, we may modify, suspend, or discontinue all or part of the Service for technical, business, legal, security, or operational reasons. If the Service is discontinued, Lifetime plan access ends when the Service ends.
  • You may cancel your subscription at any time. Access continues until the end of the billing period.
  • Refunds are handled on a case-by-case basis.

5. Usage Limits

Each plan has monthly usage limits. Exceeding these limits will result in temporary restriction of the affected feature until the start of the next calendar month. Abuse of the API or attempts to circumvent limits may result in account suspension.

6. Disclaimer

The Service is provided as is without warranties of any kind. EvidenceLens does not guarantee the accuracy, completeness, or reliability of claim verifications. AI-generated analysis may contain errors. Always consult primary sources for critical decisions.

7. Limitation of Liability

EvidenceLens shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service.

8. Changes to Terms

We may update these terms from time to time. Continued use of the Service after changes constitutes acceptance of the new terms.
