JSON Keeper — Privacy Policy

Last updated: 2026-06-16

JSON Keeper is a browser extension that formats and displays JSON documents you open or paste. This policy explains what data the extension does and does not handle.

Data we collect

None. JSON Keeper does not collect, transmit, sell, or share any personal information. There is no analytics, no tracking, no remote server, no account, and no advertising. The extension makes no network requests of any kind — everything runs locally in your browser.

Data stored on your device

The extension saves a few small preferences locally using the browser's chrome.storage.local API — your chosen theme (auto/light/dark) and view mode (pretty/raw/min), plus a temporary copy of text you paste into the popup so it can be opened in the viewer tab. This data stays on your own device, is never transmitted by us, and can be erased by removing the extension.

The JSON you view

JSON Keeper reads the content of JSON documents you open or paste solely to format and display them in your browser. That content is never sent anywhere; it is processed entirely on your device.

Permissions

• storage — to remember your theme/view preferences.
• host access (http, https, file) — so the extension can detect and pretty-print a JSON document on whatever page you open. It only reads page text to render JSON; it does not read cookies, browsing history, or other site data, and it transmits nothing.

Questions can be raised via the extension's Chrome Web Store listing or its source repository.
