Common questions
A few things people ask most often:
- Restore a purchase — open the upgrade screen in the app and tap "Restore". Purchases are tied to the store account you bought with (your Apple ID or your Google account) and restore for free.
- Manage or cancel a subscription — your app store handles this, not us: on iPhone, Settings, tap your name, then Subscriptions; on Android, the Google Play app, your profile, then Payments and subscriptions.
- Remove ads — where an app shows ads, a subscription removes them entirely. Personalization alone can be switched off without paying, in your device settings rather than in the app: on iPhone, Settings → Privacy & Security → Tracking; on Android, Settings → Privacy → Ads.
- Turn notifications on or off — from the app settings, or in your device settings under Notifications. We never penalise you for turning them off.
- Report something that looks wrong — where an app supports it, use the in-app report option and we will review it.
Your account and data
Where an app has accounts, you can delete yours and its data at any time from the app's settings — that removes your data from our servers. For the full picture of what we collect and why, see our Privacy Policy and Terms of Use.
