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.
