How Google Play Protect works
Google Play Protect checks apps when you install them. It also periodically scans your device. If it finds a potentially harmful app, it might:
- Send you a notification. To remove the app, tap the notification, then tap Uninstall.
- Disable the app until you uninstall it.
- Remove the app automatically. In most cases, if a harmful app has been detected, you will get a notification saying the app was removed.
How malware protection works
To protect you against malicious third party software, URLs, and other security issues, Google may receive information about:
- Your device's network connections
- Potentially harmful URLs
- Operating system, and apps installed on your device through Google Play or other sources.
You may get a warning from Google about an app or URL that may be unsafe. The app or URL may be removed or blocked from installation by Google if it is known to be harmful to devices, data, or users. You may get a recommendation to scan an app from outside of Google Play that has never been scanned by Google Play Protect before. Scanning the app will send app details to Google for a code-level evaluation. A short time later, you’ll receive a result letting you know if the app looks safe to install or if the scan determined the app is potentially harmful.
You can choose to disable some of these protections in your device settings. But Google may continue to receive information about apps installed through Google Play, and apps installed on your device from other sources may continue to be checked for security issues without sending information to Google.
How Google resets permissions for unused apps
To keep your data private, Google Play Protect may reset app permissions for apps you rarely use. This feature protects devices that run on Android versions 6.0–10.
Google may reset any permissions you grant from apps that you haven’t used for 3 months. When this happens, you may receive a notification from Play Protect. Play Protect doesn’t automatically reset permissions from apps that are needed for the usual operation of your device.
To review or manage which app permissions are reset
- Open the Google Play Store app
- At the top right, tap the profile icon.
- Tap Play Protect
- Tap Permissions for unused apps.
To prevent Play Protect from automatically resetting permissions:
- From the list, select an app.
- Turn off any of the options:
- Remove permissions if app isn’t used.
- Remove permissions if app is unused.
- Pause app activity if unused.
To turn this setting on and off for an individual app:
- Select the app.
- Turn on or off either:
- Remove permissions if app isn't used.
- Pause app activity if unused.
For apps that had their permissions automatically reset by Google Play Protect, you need to grant permissions again.
