Local Android file encryption apps

This cluster comprises Android apps for local file encryption and private storage, using passphrases, key pairs, or cover images to keep data on-device and offline. Dated entries before the index are sporadic single releases from 2012 to 2025, with three in July 2026. mingyue-encryption leads traction with 1 star, while OTG Master and quietport have 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
