How your CHF 5 credit works

• Your friend opens your link and starts checkout within 30 days. They can try 5 free questions per system first.
• Eligible new subscribers create or sign in to a verified account and get 10% off their first month: CHF 13.50, then CHF 15/month. After their first payment passes a 14-day validation period, you receive CHF 5 of billing credit.
• Credit reduces a future Premium bill. Refer three eligible friends and earn CHF 15. There is no annual referral limit.
• Each new subscriber counts once; your own purchases do not count. Refunded or disputed payments do not qualify, and any related credit may be reversed.
• Use the link in the same browser when starting checkout. Your friend's identity is never shown to you.
