Datenschutzrichtlinie

Your data never leaves your browser. That is our fundamental promise.

1. Local Processing

Unlike most online JSON tools, JSON Formatter processes all your data locally on your computer. We use client-side JavaScript and Web Workers to handle all formatting, validation, and conversion tasks. No JSON data you paste or upload is ever sent to our servers.

2. Information Collection

We do not collect any personal information. We do not require an account, and we do not store any of the data you process using our tools.

3. Cookies and Analytics

We may use privacy-preserving analytics to understand how our website is used. These analytics are anonymized and do not track individual users or their data. We may use local storage to remember your theme preferences.

4. Third-Party Services

This website is hosted on modern cloud infrastructure. Our hosting provider may collect standard server logs (such as IP addresses) for security and maintenance purposes, but this is separate from the JSON data you process.

5. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
