How do I cancel my plan?
Web plans: open Settings → Plan & billing and press Cancel plan, then confirm in the billing portal. You keep access until the end of the period you paid for, and Plan & billing shows the date it ends.
App Store plans: cancel in your Apple ID subscription settings at least 24 hours before the period ends.
Google Play plans: cancel in Google Play under Payments & subscriptions.
Deleting the app or your account doesn’t cancel an App Store or Google Play plan, so cancel it in the store first.
