Invite a friend

How your reward works

• Your friend opens your link and starts checkout within 30 days. They can try 5 free questions per system first.
• Your friend chooses a pass with 7 extra days and no automatic renewal, or 10% off their first month of Monthly. Their invitation shows both prices and renewal terms in their chosen currency. They need a verified account and must be new to Premium.
• After their payment passes 14-day validation, Monthly members earn CHF 3, €3, £2.60 or US$3 in their billing currency; pass members earn 14 extra days. Your plan when their checkout opens determines your reward. There is no annual referral limit.
• Pass rewards extend your pass. If it has ended, the extra days start when awarded. A change to Monthly while a pass reward is pending requires review.
• Each new member counts once; your own purchases do not count. Refunded or disputed payments do not qualify, and related credit or extra days may be reversed. Previously promised rewards keep their original terms.
• Use the link in the same browser when starting checkout. Your friend's identity is never shown to you.
