Most scanner apps quietly upload your documents. This one never does.

DokoDocs stores everything in your local encrypted Room database. Your documents stay strictly on your device unless you explicitly share or sync them. Fully open-source under Apache 2.0 with zero trackers, zero forced cloud accounts, and zero Google Play Services lock-in.
