Privacy Policy
Last updated: May 13, 2026
At jsonproject.com, your privacy is our highest priority. This tool is designed from the ground up to process everything entirely within your browser — we never receive, store, or transmit any data you enter.
1. Data We Collect
We collect no personal data. All JSON processing — formatting, minification, validation, and auto-fixing — happens locally in your browser using JavaScript. Your JSON content is never sent to any server, logged, or stored by us.
2. How the Tool Works
jsonproject.com is a fully client-side web application. When you:
- Paste or type JSON — processed entirely in your browser's memory. Never transmitted.
- Upload a file — read locally via the browser's File API. Never uploaded to our servers.
- Fetch from a URL — your browser makes a direct request to that URL. We do not proxy or log this request.
3. Cookies & Local Storage
We do not use cookies. We use browser localStorage solely to remember your preferences:
| Key | Purpose | Expires |
|---|---|---|
| theme | Remembers your dark/light mode preference | Until cleared |
| json-formatter-indent | Remembers your preferred indent size | Until cleared |
You can clear these at any time via your browser's developer tools or settings.
4. Third-Party Services
jsonproject.com does not use any third-party analytics, advertising, tracking pixels, or telemetry services (no Google Analytics, no Facebook Pixel, no ad networks). All assets — including the Monaco code editor — are served directly from our own domain.
5. Children's Privacy
Our service does not address anyone under the age of 13. We do not knowingly collect any personal information from children under 13. Since we collect no personal information from any user, this policy applies equally to all visitors.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by the "Last updated" date at the top of this page. Continued use of jsonproject.com after any changes constitutes acceptance of the updated policy.
7. Contact
If you have any questions about this Privacy Policy, please contact us at privacy@jsonproject.com.
The short version
We don't collect anything. Your JSON never leaves your browser. We store only your UI preferences (theme and indent size) in localStorage on your own device.
