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.
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.
The extension saves a few small preferences locally using the browser's
chrome.storage.local API — your chosen theme (auto/light/dark) and
color skin, view mode (pretty/raw/min), and key-sorting preference, plus a
temporary copy of text you paste into the popup so it can be opened in the
viewer tab. The temporary text is removed after the viewer reads it. All of
this data stays on your own device, is never transmitted by us, and can be
erased by removing the extension.
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.
JSON content and page access are used only to provide JSON viewing, editing, searching, diagnostics, copying, downloading, and export features requested by the user. The extension does not transfer this data to the developer or any third party, does not use it for advertising or credit decisions, and does not allow humans to read it.
Questions can be raised via the extension's Chrome Web Store listing or its source repository.
