Hello, and thank you for your question.
Subscriptions purchased through mobile apps are linked to the Apple ID or Google Play account used for the purchase and only function on devices using the same store account. Website subscriptions are separate, tied to meteoblue web accounts, and do not extend to mobile apps. Consequently, app and website subscriptions operate independently, requiring separate purchases to access premium features across all devices.
This separation arises from platform store policies, privacy considerations, synchronization challenges, and differences in feature sets. We hope we were able to answer your questions and wish you pleasant weather with meteoblue.
