Essential storage only
PDFIntro does not use advertising or third-party tracking cookies. We use your browser’s local storage to remember your theme and, optionally, your activity history.
What’s stored
A theme preference, a history on/off flag, and (if enabled) a short list of recently used tools. All of it stays on your device.
No tracking
We do not profile you across sites and we do not sell data — there is no data about your documents to sell.
Managing it
Clear everything from Settings → Clear local data, or via your browser’s site-data controls.
