Q. Do tools that use the camera or microphone upload video or audio?
No. Webcam, mic, screen recording, QR code reading, and similar tools process everything only on your device, after you grant permission in your browser. Nothing is sent to a server or stored. You can revoke permission at any time in your browser settings.
Q. Does the site store anything in my browser?
Favorites, theme, game best scores, invoice issuer details, UTM Builder history, and similar items are kept in your browser's local storage. They are never sent to a server and are removed when you clear the site's data. See the Privacy Policy for details.
Q. Why is my input still there after reloading the page?
To restore your input after a reload or a language switch, it is temporarily kept in the tab's session storage and cleared when you close the tab. Tools that handle sensitive data such as passwords or tokens do not save it.
Q. Videos and large images are slow to process.
All processing happens on your own device, so larger files take longer. Try a shorter file or a smaller image first, and use a recent desktop browser (Chrome, Edge, Firefox, or Safari).
Q. Any tips for using the site?
You can use the search and category filter on the home page, favorite tools (drag to reorder), keyboard shortcuts (see the shortcuts page), and the light/dark theme switch.
