Questions

How does the free trial work?: Start any subscription plan and you won't be charged for 7 days. We collect your card up front so access continues seamlessly — cancel anytime before the trial ends and you pay nothing.
Who handles billing?: Lemon Squeezy is our merchant of record. They run secure checkout and handle sales tax / VAT. You can manage or cancel your subscription anytime from Settings.
Can I cancel?: Yes, anytime. You keep access through the end of the period you've paid for, and all your data stays put if you come back.
