the privacy model, in plain text

Unfckr runs 100% client-side. No uploads, no servers, no accounts, no analytics, no third-party requests - the only network traffic is downloading the app itself. Files you drop are parsed on your machine; the SQL engine is SQLite compiled to WebAssembly running in your tab; recent-file history lives in your browser's IndexedDB on your device and is yours to clear.

• Verify with DevTools: use the app with the Network panel open - no request carries your data.
• Verify offline: load the page, switch to airplane mode, keep working.
• Verify the headers: the Content-Security-Policy blocks fetch, XHR, WebSockets, beacons, and form posts.
• Or make the browser prove it: the page above ends with a live test that reads back the exact policy this response carried, then tries to smuggle data out through all six channels - fetch, XHR, WebSocket, tracking pixel, script tag, form POST - and shows each one refused, naming the directive that did it. Nothing is sent anywhere: the target is under .invalid, the suffix reserved so that it can never exist.
• Shared recipe links keep the pipeline in the URL fragment, which browsers never send to servers.
