Privacy Policy

Last Updated: March 2026

1. Data Processing

At diffchecker.io, we prioritize your privacy. All diff computations are performed locally in your browser. Your text, code, or data never leaves your device unless you explicitly choose to share it by generating a link.

2. Shareable Links

When you use the "Share" feature, your diff state is encoded directly into the URL hash (the part after the `#`). We do not store this data in any database. Anyone with the link can decode and view the exact state of the diff you shared.

3. Analytics and Tracking

We use minimal, privacy-friendly analytics to understand basic site usage (e.g., page views) in order to improve our tools. We do not use intrusive tracking cookies or sell your personal data to third parties.

4. Local Storage

We may use your browser's local storage to save your preferences, such as your dark/light mode selection. This data is kept entirely on your device.

5. Contact Us
