Billing questions
Can I cancel anytime?
Yes. Cancel any time before your renewal date from Settings → Manage billing in the app. Pro stays active until the end of the period you have paid for, then your account returns to Free. Partial periods aren’t refunded; see the refund policy.
What happens to my repertoire if I downgrade?
Nothing is deleted. Your lines, notes and training progress stay exactly as they are; only the Pro limits come back.
Do unused credits carry over?
Pro's 500 monthly credits reset every 30 days. Credits from packs and your 25 starter credits never expire.
Which currency, and what about tax?
Prices are in US dollars. Any sales tax or VAT that applies to you is shown at checkout before you pay.
