Privacy Policy

Last Updated: December 2025
Welcome to re-polish ("we," "our," or "us"). We are committed to protecting your privacy and your intellectual property. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Spine 2D optimization tool at re-polish.com.

1. Information We Collect

We collect minimal data necessary to provide our services and verify your subscription status.


A. Account Information (via Patreon)


When you log in using Patreon, we receive the following information from their API:


  • Patreon User ID: To identify your account.
  • Email Address: To communicate with you regarding service updates (we do not spam).
  • Membership Status: To determine if you have access to premium features (Active/Inactive pledge).
  • Full Name: As provided on your Patreon profile.

We do NOT collect or store passwords. Your authentication is handled entirely by Patreon.


B. User Content (Your Files)


To use the re-polish editor, you upload Spine 2D project files (.json, .atlas, .png).


Processing: These files are processed locally in your browser (using Web Workers technology) or transiently on our secure servers solely for the purpose of optimization.


No Storage: We do not store, archive, or claim ownership of your uploaded assets. Once the optimization session is closed or the page is refreshed, your data is cleared from the application memory.

2. How We Use Your Information

We use the collected information for the following purposes:


  • Service Access: To verify your Patreon pledge level and unlock specific nodes (e.g., Re-Pack, Re-Curve).
  • Preferences: To remember your editor settings (e.g., theme, node graph layout) via Local Storage.
3. Payment Information

We do not process payments or store financial information.


All transactions are handled securely by Patreon. We never have access to your credit card number, bank account details, or billing address. Please refer to Patreon's Privacy Policy for information on how they handle your financial data.

4. Cookies and Local Storage

We use browser Local Storage to enhance your experience. This allows us to:


  • Keep you logged in during your session.
  • Save the state of your node graph so you don't lose work if the tab closes accidentally.
  • Store your UI preferences.

We may use third-party analytics tools (like Google Analytics) to understand how users interact with our website to improve performance. These tools may use cookies to collect anonymous usage data.

5. Third-Party Services

We integrate with the following third-party services:


  • Patreon: For authentication and subscription management.
  • Vercel: For hosting our website (they may log IP addresses for security purposes).

We recommend reviewing the privacy policies of these services for more information on their data practices.

6. Data Security

We implement industry-standard security measures to protect your data, including HTTPS encryption for all communications. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.

7. Your Rights

You have the right to:


  • Access: Request a copy of the personal data we hold about you.
  • Deletion: Request that we delete your account and associated data.
  • Opt-out: Unlink your Patreon account at any time.

To exercise these rights, please contact us using our feedback form.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last Updated" date.
