100.tools
Privacy
100.tools is built to keep common processing tasks inside the browser whenever possible.
Local processing first
When a tool can run entirely in the browser, pasted input and generated output stay on your device. The page should clearly indicate when a tool runs locally.
What may be stored in the browser
Favorites, recent history, and feedback drafts may be stored in local browser storage so the interface can remember your choices on this device.
Future data-handling changes
If a future tool requires upload, networking, or a server-side action, the tool page and this policy should be updated before that behavior becomes the default.
