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.
