Dusk Premium is billed by Apple or Google, so it is managed in your store account. In the app, Settings › Dusk Premium › Manage or cancel subscription opens the right page.

iPhone: Settings › your name › Subscriptions › Dusk. Android: Play Store › your profile › Payments & subscriptions › Subscriptions › Dusk.

Cancel at least 24 hours before the trial or the current year ends and you won’t be charged again. You keep Premium until the end of the period you paid for.

On a new phone, or after reinstalling, open the paywall or Settings › Dusk Premium and tap Restore purchases. Use the same Apple Account or Google account you subscribed with.

Refunds are handled by the store that billed you. iPhone: reportaproblem.apple.com. Android: the order in Play Store › Payments & subscriptions › Budget & history, or Google Play’s refund page.

Your logs live only on your phone. Settings › Your data › Export as JSON saves a copy of everything; Delete all data removes it from the phone. Uninstalling Dusk deletes it too, and there is no copy on our servers to recover it from.

AI features can be switched on or off any time in Settings › AI features. Apple Health and Health Connect data never leave your phone. The privacy policy has the details.

Dusk is a sleep-habit tool for general wellness. It does not diagnose or treat any condition. If you have loud snoring, pauses in breathing, or trouble sleeping most nights for three months or more, please talk to a doctor.
