Our core commitment
PDFIntro processes every file on your device, inside your browser. We operate no server that receives, stores, or has access to the contents of your documents. There is no upload step and nowhere for your files to go.
What we do not collect
We do not collect, transmit, or store the contents of any PDF or image you open. We cannot read your files — the code that processes them runs in your browser tab, not on our infrastructure.
Data stored on your device
If you leave activity history enabled, a short record of which tools you used and when is saved in your browser’s local storage. This never leaves your device and you can disable or clear it at any time in Settings.
You control deletion
You can clear all locally stored data instantly from Settings → Clear local data, or by clearing your browser storage for this site. Because nothing is held remotely, that deletion is complete.
Third-party assets
Core libraries load from a public CDN on first visit. These requests deliver code to your browser; they do not carry your documents. After caching, the app can run offline.
