Refund policy
When we give your money back for a semester bought on hsmath.app.
Within 7 days
If a semester isn't what you expected, ask within 7 days of it opening on your account and before you've watched more than 3 of its paid lessons. We'll refund it in full and close the semester on your account.
Mistakes and problems
- Paid twice, or paid more than the price: we refund the difference.
- Paid but the semester never opened, and we can't fix it: full refund.
- Lessons don't play because of a fault on our side that we can't fix within a reasonable time: refund for that semester.
When we don't refund
- After 7 days, or after more than 3 paid lessons have been watched, unless one of the problems above applies.
- Accounts suspended for sharing lessons or accounts.
- A prepaid code that has already been redeemed.
Prepaid cards
An unused prepaid card can be returned to the seller you bought it from, on their terms. Once a code is redeemed it works like a semester bought on hsmath.app.
How to ask
Write to [email protected] from your account's email with the semester and the payment's transaction number. We answer within 3 working days and send refunds back to the same FIB, FastPay or QiCard account you paid from, usually within 7 working days.
