JSONLab

Privacy Policy

Last updated: June 21, 2026

This Privacy Policy explains how JSONLab ("we", "us" or "our") handles information when you use our website and tools (the "Service"). JSONLab is built to be privacy-first, and this policy reflects that commitment.

1. Your data stays in your browser

JSONLab is a client-side application. All JSON you paste, type, open or convert is processed entirely within your browser on your own device. We do not upload, transmit, store or have any access to the content you work with. Sensitive data such as API payloads, configuration files and logs never leaves your machine.

2. Information we do not collect

  • We do not collect or store the JSON or other content you process.
  • We do not require an account, sign-up, or any personal information to use the Service.
  • We do not sell or share any personal information, because we do not collect it.

3. Local storage

To improve your experience, JSONLab may store small preferences (such as your selected theme) in your browser's local storage. This information remains on your device, is not transmitted to us, and can be cleared at any time through your browser settings.

4. Cookies and tracking

JSONLab does not use advertising cookies or third-party tracking scripts. The Service is ad-free and does not load third-party analytics or tag-manager scripts.

5. Hosting and server logs

The website's static files are delivered by a hosting provider. Like most web hosts, the provider may automatically record standard technical request information (such as IP address, browser type and timestamp) for security and operational purposes. This is limited to delivering the page itself and does not include the content you process within the app.

6. Third-party links

Our Service may contain links to third-party websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies.

7. Children's privacy

The Service is not directed to children under the age of 13, and we do not knowingly collect personal information from children.

8. 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.
