If I subscribe on iOS, can I access the Premium mode on an Android device?
A subscription is valid for all devices where you are logged in, independently of the operating system (i.e. it is possible to subscribe on iOS and use the app on an Android phone or vice versa), however, it can only be used on a single device at any time. To use the same account from multiple devices you have to login (sign up) on the first device using either your e-mail address, your Facebook account or Google account.
On the second device or any other further devices, when starting the app, choose the ‘I have an account” option to log in with your existing account.
Please note that you can only cancel or modify your subscription on the original platform (Android, iOS, or PayPal) you used for purchasing the subscription.
