A real person answers on WhatsApp. It is the fastest route for anything to do with payment.

I paid but my plan is not active yet
Send the payment screenshot on WhatsApp. Plans are activated by hand, usually within two hours. If longer has passed, send it again and say roughly when you paid.
I changed phone — is my progress gone?
Sign in with the same account on the new phone and everything comes back: progress on the path, your streak and your plan. Progress belongs to the account, not the handset.
A question has the wrong answer
Use the report control on that question in the app. It goes straight into a moderation queue. A wrong answer in the bank is the fastest thing we fix, because one bad key can teach a hundred people the wrong fact.
Hearts ran out and I want to keep going
Practice mode does not spend hearts at all, and it allows three times the daily limit. It is there precisely so running out never means stopping.
I want my account and data deleted
Use the account deletion page. Deletion removes your profile, progress and answers permanently — it cannot be undone, and a new account starts from zero.
