Privacy Policy

Last updated 9 November 2026

Blackjack Theory is a training app for blackjack basic strategy and card counting. We built it to collect as little as possible: there are no accounts, no ads, no analytics and no tracking.

Data stored on your device

Your practice progress (rating, accuracy, sessions, streaks), table settings, practice chip balance and reminder preferences are stored only on your device. They are not sent to us. Deleting the app deletes them.

Purchases

Subscriptions and the Lifetime purchase are processed by Apple (App Store) or Google (Google Play). We never see your name, email address or payment details.

We use RevenueCat to check whether you have Pro. RevenueCat receives a random, anonymous app user ID, your purchase history for this app, and basic device information (such as the operating system version and country) so it can validate purchases and restore them. This information is not linked to your identity and is not used for advertising.

Notifications

Daily reminders and streak alerts are scheduled on your device. No push token or notification data is sent to us. You can turn them off in the app's settings or your phone's settings.

Children

Blackjack Theory simulates casino gambling with practice chips that have no cash value. It is not directed at children and is rated 17+ on the App Store and 18+ on Google Play.

Changes

If this policy changes, we'll update this page and the date above.
