Thirty days.
No questions.

If the book didn't help, I don't want your money.

Reply to the receipt email from Whop within 30 days of buying and say refund. That's the whole process. You'll have it back within a few days, and I won't ask why.

You can also write to jackcoleus@proton.me from the address you bought with.

Payments are handled by Whop, who appear on your statement.
