Privacy Policy
The short version: we never store your files — we never even see them.
Your files never leave your device
Every tool on fltools runs entirely in your web browser using JavaScript and WebAssembly. When you select a file, it is read by your browser on your own device and never transmitted to us or anyone else. We do not operate any file-processing servers.
What we can (and cannot) see
Because processing is local, we cannot see, access, copy or store your files or their contents. The only information we receive is ordinary, anonymous website analytics (page views), exactly like any static website.
Cookies, storage and ads
We use localStorage/sessionStorage to remember your theme choice and to avoid showing the adblocker notice more than once per session. If ads are enabled, Google AdSense may set its own cookies — you can opt out in Google's ad settings. No personal data is sold.
Your rights
Since we collect no personal files or accounts, there is nothing of yours stored on our side to export or delete. Clearing your browser storage removes all fltools preferences instantly.
