Privacy Policy

Last Updated: 2026-10-18

Data Collection

JSONKit does not collect or store your JSON data. Almost every tool runs entirely in your browser: the JSON you paste is parsed, formatted, validated, converted and compared on your own device and is never sent anywhere. The one exception is JSON to Code, which sends your JSON sample to our server to generate type definitions and returns the result immediately; the input is not logged or stored.

Local Storage

We use browser local storage to save your preferences (such as theme settings) and to remember your last input for convenience. This data is stored only on your device and is never sent to our servers.

Cookies and Third-Party Services

We use the following third-party services that may set cookies:

  • Google AdSense: Used to display advertisements. Google may use cookies to personalize ads based on your browsing history.
  • Google Analytics: Used to understand which tools and features are used so we can decide what to improve. Google Analytics uses cookies and records pages visited plus anonymous usage events such as the tool name, the action (e.g. format or convert), the selected format or language, and a rough input size range. The JSON or other text you enter is never sent to Google Analytics. You can opt out with the Google Analytics Opt-out Browser Add-on or by blocking cookies.
  • Vercel Analytics: Used to understand how visitors use our site. Vercel Analytics does not use cookies and collects no personal data.

Third-Party Links

Our website may contain links to third-party websites. We are not responsible for the privacy practices of these external sites. We encourage you to read the privacy policies of any linked websites you visit.
