Required Permissions

1. Modify System Settings (WRITE_SETTINGS):

• Necessary for the app to adjust the system screen timeout values on your behalf.

2. Foreground Service (FOREGROUND_SERVICE):

• Ensures the app can actively monitor screen-off events and system timeout changes in the background.

3. Request Ignore Battery Optimizations:

• Prevents the Android operating system from aggressively closing KeepOn while it is actively managing your screen.

FAQ

Q: Does KeepOn track my usage data or require an active internet connection?

A: Privacy is a core pillar of KeepOn, as the app does not include any tracking mechanisms and does not even request internet permission from your device. This design ensures that your data never leaves your smartphone and remains entirely under your control at all times.

Q: How does the flexible timeout control feature actually work in practice?

A: The app allows you to set your screen to stay active for any specific duration you choose, effectively bypassing the standard system limits. A great feature of KeepOn is its ability to automatically restore your original system timeout settings as soon as you manually turn the screen off, so you never have to worry about manually changing them back later.

Q: Can I use KeepOn with automation tools like Tasker or Locale?

A: Yes, KeepOn includes an integrated plugin specifically designed for Tasker and Locale, making it a powerful choice for users who enjoy automation. This functionality allows you to trigger screen timeout changes programmatically based on specific conditions, such as when a certain app is opened or when your phone is connected to a power source.
