If you subscribed in the app, Premium is billed by Apple or Google, so you cancel or change it in their subscription settings. Castria has a shortcut: Settings → Change plan. If you subscribed on castria.app, use Manage subscription in Settings on the website.
- From Castria: open Settings. On your Subscription card, tap Change plan, Payment method or Billing history. Each opens your store's subscription page, where you can also cancel.
- On iPhone: open the Settings app, tap your name, then Subscriptions → Castria.
- On Android: open Google Play, tap your profile picture, then Payments & subscriptions → Subscriptions → Castria.
- On castria.app: sign in, open Settings, and tap Manage subscription on your Subscription card. You can cancel, change your plan or update your card there.
When you cancel, Premium keeps working until the end of the period you've paid for. After that:
- your smart playlists stay, but you can't edit them;
- your cloud storage becomes read-only.
Skipping ads on your phone keeps working for free.
If you subscribed on one device and now use another, manage the subscription where you paid: the App Store, Google Play or castria.app.
