Marble Terms
Updated 10 October 2026
Use of Marble is governed by Apple's standard licensed application end user license agreement. Subscriptions are billed and managed by the App Store. These terms add the rules for referrals.
Referrals
- Share your referral code with a friend. If they haven't had Marble Pro or its free trial, they get 1 month of Marble Pro free when they enter it in Marble. After that month, their subscription renews at the usual price unless they cancel it in their Apple Account's subscriptions.
- A friend counts once their free month starts. When 1 friend has, you can redeem 1 month free of Marble Pro; when 3 friends have, 2 more months; when 5 friends have, 3 more months. That is at most 6 free months in a calendar year, counted in UTC; the count starts again on January 1.
- Rewards are App Store offer codes. If you subscribe, the free months start at your next renewal; if you don't, redeeming one starts Marble Pro, which then renews at the usual price unless you cancel.
- Referrals are for people you know. Codes used by the same person on several Apple Accounts, bought, sold, or posted to collect rewards don't count, and we may withhold or cancel those rewards. We may change or end referrals at any time; rewards already redeemed are kept.
