Privacy Policy

Last updated: May 2026

1. Overview

jsonutils.app is committed to protecting your privacy. This policy explains what information is collected when you use this website and how it is handled.

The most important thing to understand is this: all tool operations run entirely in your browser. Any JSON, XML, or other data you paste into a tool is never transmitted to any server. It is processed locally by JavaScript running in your browser tab and goes nowhere else.

2. Data collected by tool operations

None. The formatters, validators, converters, code generators, and all other tools on this site perform zero network requests when processing your data. You can verify this by opening your browser's DevTools network panel while using any tool.

No content you enter is stored, logged, or accessible to us in any way.

3. Technical data and analytics

Like any website, standard server logs may capture technical information such as your IP address, browser type, operating system, and the pages you visit. This data is used solely for security monitoring, abuse prevention, and understanding general usage patterns.

We may use privacy-respecting analytics to measure aggregate page traffic. This does not involve tracking individual users, and no personal profiles are built.

4. Advertising

jsonutils.app may display advertisements served by third-party networks, including Google AdSense. These networks may use cookies or similar technologies to serve ads based on your browsing behaviour across sites. You can opt out of personalised advertising through your browser settings or via Google's ad settings.

5. Cookies and local storage

This site uses browser localStorage to remember your theme preference (light or dark mode). This data never leaves your device and is not a cookie in the traditional sense.

Third-party services (advertising, analytics) may set their own cookies. You can manage or delete these at any time through your browser settings.

6. Third-party services

This site loads resources from third-party providers to function correctly:

  • Google Fonts: Serves the Inter and JetBrains Mono typefaces. Google may log font requests including your IP address.
  • jsDelivr: Serves the Tabler Icons icon font. jsDelivr may log CDN requests.
  • Google AdSense: May serve advertisements and set cookies for ad personalisation.

These providers have their own privacy policies. We do not control the data they collect.

7. Data retention

We retain little to no identifiable personal data. Server logs are kept for a limited period for security purposes and then deleted. No user accounts exist, so there is no profile data to retain.

8. Your rights

Depending on your jurisdiction, you may have the right to request access to, correction of, or deletion of any personal data we hold. Given the nature of this service, we hold minimal identifiable data. For any request, contact us at the address below.

9. Changes to this policy

We may update this policy from time to time. Changes will be reflected on this page with a revised date at the top.
