  • habits;

is stored locally on the device. HabitKai does not create user accounts and does not require authentication. The user is responsible for:

Payments are processed through the Google Play Store and may be managed through third-party platforms, including RevenueCat.

6. Payments, Renewal, and Cancellation

Subscriptions renew automatically unless canceled by the user through the Google Play Store before the renewal date. Canceling a subscription prevents future charges while maintaining premium access until the end of the already paid period.

"Lifetime" purchases grant permanent access to the premium features available at the time of purchase, except in cases of technical impossibility, legal requirements, or permanent discontinuation of the App.

Except where otherwise required by law, refunds are not provided. Billing and payment matters may be subject to Google Play Store policies.
