Program overview
Invite friends lets customers recommend us to people they know. The invited friend receives a discount code for their first challenge purchase, and the inviter receives a discount code for each invited friend's first paid challenge purchase. Rewards are discount codes only — never cash. Your link, invites and codes are on the Invite friends page.
How the codes work
Each code can be used once, only on the account it was issued to, and only on challenge packages. It cannot be combined with another code or with a package that is already on sale. The discount, any maximum amount and the validity are shown on the Invite friends page and in the e-mail with the code. Codes already issued keep the terms they were issued with.
When codes are issued
The friend's code is sent after the friend verifies their e-mail address. The inviter's code is issued after the friend's first paid challenge purchase is confirmed and the review period shown on the Invite friends page has passed. A free demo is not a purchase. Each customer can earn up to 10 inviter codes per calendar month (UTC); a friend's purchase beyond that limit earns no code.
One inviter, one program
A friend can only be invited before their first purchase and is credited to one inviter and one program: a customer referred through a partner's link is not part of Invite friends. Members of our partner program share their partner link instead.
Fair use
Inviting yourself, using several accounts, or a purchase made on the inviter's own device earns no code. If a friend's purchase is refunded, an unused inviter code is cancelled. We may cancel codes obtained through abuse and take action on the accounts involved.
Changes
We may change or end the program at any time. Codes already issued stay valid until they expire, unless they were obtained through abuse.
