Privacy

PDF processing happens on your device. PDFs go only between this browser and Google Drive, or to your explicit download. No analytics or developer server is used. Google receives authentication and Drive API requests. Local recovery copies remain on this device until cleared; clear drafts on shared computers.

New marks are flattened into the exported PDF for broad visibility. They remain editable in Markr through the local draft, but are not individually editable annotations in other PDF viewers. Feedback text is exported as vector outlines, so it stays sharp but is not selectable text.
