Privacy policy — DocScan

DocScan is a document scanner. Scans are processed and stored on your device; there are no accounts and no cloud sync, and your documents are never uploaded by DocScan. The free tier shows ads served by Google AdMob, and the optional one-time “DocScan Pro” purchase is handled by Google Play Billing — those two services use the network and are described below. Everything else works offline.

Photos and camera

DocScan accesses the camera only with your permission to photograph documents. Gallery import accesses only the images you choose through Android's picker. Photos, crops, enhancement settings, and document names are processed on your device and stored in DocScan's private storage. Device motion may be used locally to steady the framing guide; it is not uploaded or retained as a log in production builds.

Ads (free tier)

Free users see ads provided by the Google Mobile Ads (AdMob) SDK. To serve ads, Google may collect device and advertising identifiers, approximate location derived from IP, and ad interaction data, as described in Google's privacy policy (policies.google.com/privacy) and “How Google uses information from sites or apps that use our services”. Where required (for example in the EEA, UK and Switzerland), DocScan shows a consent message first; you can revisit your choices any time under Settings → Ads & privacy. Purchasing DocScan Pro removes all limits — ads keep running to support development unless you switch them off in Settings. DocScan itself never shares your scans with ad services.

Purchases

DocScan Pro is a one-time in-app purchase processed entirely by Google Play. DocScan learns only whether your Google account owns the product; payment details never reach the app. Refunding the purchase removes Pro features.

Sharing and exports

When you choose Save to device, DocScan writes a PDF or JPEG to shared device storage. Android 8 and 9 require storage permission for this action. When you choose Share, Android gives the app you select temporary read access to the chosen file. That receiving app or storage service handles the copy under its own privacy policy. DocScan does not upload documents itself.

Retention and deletion

Scans remain on your device until you delete them, clear DocScan's app data, or uninstall the app. You can delete a scan in My Scans, or delete all scans in Settings. Delete all scans also removes any retained diagnostic copies from earlier beta builds. Files already exported or shared are separate copies; delete those using the receiving app or your device's file manager. Temporary sharing files may remain in private cache so the recipient can read them; old sharing files are removed when you share again, and Android may also clear cached files. Clearing app data removes the private cache.

Security and backups

Android's app sandbox protects private scans from ordinary access by other apps. Sharing uses temporary file-access grants. DocScan keeps your scans, its database and your settings out of Android cloud backup and automatic device transfer. One small exception: your free-export counter and Pro status are included, so reinstalling or changing phones does not reset your free plan. Export files you want to keep before uninstalling, clearing app data, or changing phones. Production builds do not collect diagnostic photo or sensor logs.

Children and policy changes

DocScan does not request age information or intentionally collect data from children. Updates to these practices will be reflected in this policy.
