Privacy Policy

Last updated: June 21, 2025

This Privacy Policy explains how ThumbLion ("we", "us", or "our") collects, uses, and protects your personal information when you use our website and services. By using ThumbLion, you agree to the practices described in this policy.

1. Information We Collect

We collect the following categories of information:

  • Account information: When you register, we collect your name, email address, and a hashed version of your password.
  • Payment information: Billing details are processed by our third-party payment providers (e.g., Stripe). We do not store full card numbers on our servers.
  • Thumbnail images: Images you upload for analysis are stored temporarily to display your analysis history and are never used to train AI models.
  • Usage data: We log pages visited, features used, and timestamps to help us improve the service and prevent abuse.
  • Device & browser data: IP address, browser type, operating system, and referral URLs collected automatically via server logs.

2. How We Use Your Information

  • To create and maintain your account and authenticate your sessions.
  • To process payments and manage your credit balance.
  • To run AI thumbnail analysis on the images you submit.
  • To send transactional emails (e.g., password resets, payment receipts).
  • To detect fraud, abuse, and security threats.
  • To improve our products through aggregated, anonymized analytics.

3. Data Sharing

We do not sell your personal data. We may share information with:

  • Payment processors (e.g., Stripe) to complete transactions.
  • AI providers to perform thumbnail analysis. Images are transmitted over encrypted connections and are not retained by the provider beyond the duration of the API call.
  • Hosting and infrastructure providers for operating the service.
  • Legal authorities when required by law or to protect our rights.

4. Data Retention

We retain your account data for as long as your account is active. Uploaded thumbnail images are retained for up to 90 days after your account is closed or upon request. You may request deletion of your data at any time by contacting us.

5. Cookies

We use session cookies to keep you logged in and functional cookies to remember your preferences. We do not use third-party tracking or advertising cookies. You can disable cookies in your browser settings, but this may affect login functionality.

6. Security

All data is transmitted over HTTPS. Passwords are hashed using industry-standard algorithms. We apply reasonable technical and organizational measures to protect your data against unauthorized access, but no internet transmission is 100% secure.

7. Your Rights

Depending on your jurisdiction, you may have the right to:

  • Access the personal data we hold about you.
  • Correct inaccurate data.
  • Request deletion of your data ("right to be forgotten").
  • Object to or restrict certain processing.
  • Data portability (receive your data in a machine-readable format).

To exercise any of these rights, contact us at the address below.

8. Children's Privacy

ThumbLion is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can delete it.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify registered users by email for material changes. Continued use of the service after changes constitutes acceptance of the updated policy.
