App Lock
Open Source Android App Locker & Privacy Guard
---
## Overview
AppLock is a modern, open-source Android app locker designed to protect your privacy and sensitive
data. Lock any app, prevent unauthorized access, and enjoy a seamless Material You experience. No
root required.
> [!CAUTION]
> Google Play Protect is blocking some people from installing/updating App Lock because it uses Overlay Permission. It uses a false pretext of "this app may try to access sensitive information"
> without any base or information. If this happens to you, consider disabling Play Protect temporarily as mentioned [here](https://www.airdroid.com/quick-guides/disable-google-play-protect).
>
> You may enable it back later after you install the app. We understand this introduces unnecessary friction but there's nothing we can do about it. Google does not like it
> when other developers try to fill the gaps they create themselves.
> [!NOTE]
> You may confirm that the app is completely secure
