Billing questions
- Can I cancel anytime?
- Yes. Cancel from your account page in two clicks. You keep Premium until the end of the period you paid for, and you won't be charged again.
- How does Lifetime work?
- You pay once and keep Premium for good, including every exercise we add later. There's no subscription and nothing to cancel. If you're already on a monthly or yearly plan, you can switch to Lifetime and your old plan stops renewing.
- Can I get a refund?
- Yes. If you're not happy for any reason, contact us and we'll refund your payment in full.
- What happens to my progress if I cancel?
- Nothing is lost. Your XP, streak and solved exercises stay on your account, and the free exercises stay open.
- How do payments work?
- Payments are handled by Stripe. We never see or store your card details. You'll get a receipt by email for every payment.
- Do you offer plans for schools and teams?
- Yes. Contact us with the number of seats you need and we'll set you up with a group plan.
