Can I change or remove my partner code?

Yes, until your first payment. On the plans screen or in You → Subscription, tap Clear next to the code to remove it, or tap Partner code and apply a different one. The latest code you apply replaces the earlier one. Your price stays the same either way.

Your first successful subscription payment locks the code applied at that moment. After that, the code is shown read-only and cannot be added, changed or removed, including by support.

Codes count for a first subscription only. If your account has had a paid Calsa subscription before, the field shows "Codes count for a first subscription only" and does not save the code. Restoring a purchase, changing plan or paying through another billing service does not add a new code.
