Your choices. Visible controls.
What stays on your device, what uses online services and what you can change.
Local progress is separate.
Course and personal progress are stored on the device. Purchase restoration restores eligible access, not local progress; deleting the app can remove local data.
Registration is optional.
The main app can be used with a guest identity. Sign-in is optional; verified-account requirements apply separately to Community. Guests still need Premium for core paid tools.
Online services have a purpose.
Accounts, access validation, purchases and Community use server services, including Firebase and RevenueCat. Not all app data stays offline; the privacy policy explains the details.
Protection depends on the platform.
App choices and schedules are handled on the device. Android website filtering relies on a third-party Private DNS service, with its own data handling and network limitations.
Paid access is explained before purchase.
Subscriptions renew automatically unless cancelled; Lifetime is a one-time purchase. Availability, prices and terms can differ by store and region. Read the current offer before confirming.
Read the full terms.
Privacy, terms, Community rules, support and deletion information remain accessible from every page. Optional website analytics run only with your consent, without advertising pixels or links to your app profile. You can change your choice in the footer.
PrivacyRIALZA offers self-management and educational tools, not medical treatment or emergency support.
