Feature: App lock option

Functionality

Issue

The app can currently be opened by anyone with access to the device, and previews of potentially NSFW content linger in the recent apps list unless the app is manually closed. For privacy reasons, this might be undesirable.

Feature

• Add an option to require password/PIN/biometric authentication when first opening the app, and when switching back to it from the recent apps list.
• Black out or blur the app's preview in the recent apps list while the option is enabled.
• Optionally, add a setting to only lock the app after x minutes from last use (makes quick switching between apps less cumbersome).

Additional context

For reference purposes, I think EhViewer is a related app that implements this well.

Great suggestion.
Pin or password is doable, but biometric ones is out of my expertise, I need to research about that one.

This feature is baked into Android 13. You can secure any app you choose natively. I have it on my pixel 7 and Samsung tablets.

Well not really, Stock Android 13 (AOSP) doesn't have such a feature, it's vendor-specific feature (including google).

So I think it's still important to implement our own lockscreen.
