Your CCleaner Android Pro subscription automatically activates on all devices that are signed into the Google account you purchased the subscription from. If you already have a subscription but the premium features are not available in the app, ensure that you are signed into the correct account in Google Play Store.
Alternatively, manually check for a valid subscription by following these steps:
- Tap the menu icon at the top-left of the app interface.
- Tap Settings, then tap Subscription.
- Tap Restore previous purchase.
CCleaner Android checks for a subscription registered to the Google account you are currently signed into and activates it on your device.
