How billing works
Through the store, cancel in a tap
Payment runs through the App Store or Google Play, so CHARM never sees your card. Subscriptions auto-renew until you cancel (anytime, from your store account), and restore purchases is supported if you switch devices. Invite codes: already a subscriber? Send a friend a free month, on us.
A note on honesty
Entrainment effects are modest and unproven: a calm space for breathing, not intended for treatment. You’re paying for a crafted, honest, ad-free space to breathe, never for a treatment.
The whole solar system
One price.
No small print.
Entrainment effects are modest and unproven: a calm space for breathing, not intended for treatment. You’re paying for the craft and the quiet, never for a cure.
