Your PRO subscription is linked to your Studo account, which secured via your telephone number.
If you have completed your PRO subscription on your Android device and are now using an iOS device (or vice versa), you can "take along" the subscription without canceling: Simply log in on both devices with the same phone number. So you can also use a PRO subscription on several devices (e.g. smartphone & tablet) at the same time. 🙂
We do our best to continuously improve Studo - that's why your opinion is very important to us! In the event of a cancellation, please inform us in the Feedback & Support area in the app or at firstname.lastname@example.org about your reason for cancellation, in most cases we can solve problems or ambiguities immediately. Don't forget: Uninstalling the app does not automatically cancel the PRO subscription. Depending on how you have completed your subscription, there are different ways to manage or cancel it:
Manage PRO subscription purchased on Android (via Google Play Store)
You can cancel the subscription on your PC, Android device or iPhone / iPad. To do this, follow these instructions. If you have more than one Google account, please note that the same Google account must be used for the cancellation as the one you used for signing up for the subscription.
If you want to change your payment method, you will find all information here.
Manage PRO subscription purchased on iOS (via Apple App Store)
You can manage or cancel your PRO subscription on your iPhone / iPad, Mac or PC. Apple is providing here a guide.
You have an iPhone now, but you purchased the PRO subscription on Android (or vice versa)?
Cancel the PRO subscription on the store you purchased it on. Note that you don't need an Android phone or iPhone to cancel the subscription. You can also cancel it on the web (see the links above).
The PRO subscription cancellation didn't work?
