Privacy Policy

Last updated: August 2026

This policy explains what happens to your data when you use jsonforge.app (https://jsonforge.app). The short version: the JSON, XML, or text you paste into any tool on this site is processed entirely in your browser and is never transmitted to our servers.

1. Data you paste into a tool

Every tool on jsonforge.app — the formatter, tree viewer, table converter, repair tool, escape/unescape utility, XML converter, compare tool, visual editor, and inspector — runs entirely client-side using JavaScript in your browser. The content you paste or type into an input field is never sent over the network to us or to any third party. We have no server-side endpoint that receives it, so we could not access it even if we wanted to.

2. Information collected automatically

Like most websites, our hosting infrastructure automatically logs standard request metadata for security and performance purposes — things like IP address, browser type, referring page, and timestamps. This is infrastructure-level logging common to virtually all web hosting, and is not linked to the content of any tool you use.

3. Local storage

We use your browser's local storage to remember one thing: your light/dark theme preference. This stays on your device and is never sent anywhere.

4. Advertising and cookies

jsonforge.app may display ads served by Google AdSense. Google and its partners use cookies (including the DoubleClick DART cookie) to serve ads based on your visits to this and other sites, in order to provide advertisements about goods and services that may interest you. You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising by visiting aboutads.info.

5. Browser extension

We also publish a companion browser extension, "JSON Viewer by JsonForge.app", for Chrome and Chromium-based browsers. It detects when a tab you navigate to is a raw JSON API response and displays it as a formatted tree, table, or other view; its popup also lets you paste JSON manually. Like the rest of jsonforge.app, all formatting happens locally in your browser — the extension collects no analytics, and never transmits the content of any page or any JSON you view to us or to any third party.

  • Content script: runs on page load to check whether the page is a raw JSON response. If it isn't, the extension does nothing further and reads nothing else from the page.
  • activeTab / scripting permissions: let the popup read what the content script already found on the tab you're currently viewing, and only when you open the popup.
  • Clipboard: read only when you click "Paste" in the popup, never automatically.

6. Children's privacy

jsonforge.app is not directed to children under 13, and we do not knowingly collect personal information from children.

7. Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated “last updated” date.
