PDF1 is built to process documents on your device. We do not operate an account system, advertising service, analytics service, or cloud upload service. Files you select are read only to perform the action you request. PDF1 does not transmit document contents off your device. Files you save are written to the location you choose using Android's system file picker. Camera access is requested only when you open Scanner. Camera images are used locally to create scanned PDF pages and are not uploaded or shared. PDF1 does not collect, sell, share, or transmit personal information or document contents. It has no ads, analytics, trackers, or internet permission. PDF1 stores up to 30 recent saved-file names and Android document references locally. Document processing is performed locally. PDF1 supports password-protected PDF copies and does not store passwords after the current operation. Cleartext network traffic is disabled. App backup is disabled
