I got a new phone. How do I get my subscription back?

Sign in to the same Calsa account you used before. Your subscription is recognised across the web and mobile apps, so a new phone does not require a new purchase. For a store purchase, use Restore purchases with the store account that bought it.

If access is still missing, check your sign-in method and receipt's billing service. Apple sign-in may use a private relay address. Contact support with the purchase reference and what restoration shows. Do not buy another subscription to recover the first one. A receipt alone does not prove ownership of the Calsa account.
