A question, a problem or an idea for Castiel? Write to me at castiel@kevin-baur.com. I reply in English or German.

How do I restore my Pro purchase?

In Castiel, open the Pro screen and tap "Restore purchases" at the bottom. Use the same Apple ID or Google account you bought with. If you have a Castiel account, Pro also comes back when you sign in.

How do I cancel my subscription?

Subscriptions are managed in your Apple or Google account: on iPhone under Settings, your name, Subscriptions; on Android in the Play Store under Profile, Payments and subscriptions. Deleting the app or your account does not cancel a subscription.

My prayer alarm does not ring

Check that notifications are allowed for Castiel and the volume is not at zero. On Android it often helps to turn off battery optimisation for Castiel and to allow "Alarms and reminders". More in the Terms of Use, section 4.

I cannot hear a bell

Make sure your device is not muted and the media volume is turned up. If that does not help, restart the app.

How do I delete my account?

In the app under "Your account", "Delete account". This permanently removes your account and all community data. If you can no longer get into the app, email me from your account's email address at castiel@kevin-baur.com. All steps, and what is deleted, are on Delete account.
