Privacy policy

Blackjack School · last updated: 7 August 2026

What we collect

Nothing. The app does not collect, transmit or store personal information of any kind.

It never requests or accesses your location, camera, microphone, photos, contacts, calendar, health data, advertising identifier, or any other device data.

What the app stores on your device

So that your progress is still there next time you open it, the app saves four things in local storage on your iPhone or iPad. None of them ever leave the device:

• The table rules you configure — deck count, soft 17, surrender and the rest.
• Your practice statistics — decisions made, correct answers and streak.
• The hands you got wrong, so it can bring them back to you later.
• The practice filter you had selected.

This is saved using the standard iOS preferences mechanism and is readable only by the app itself.

How to delete it

Delete the app. iOS removes everything it stored. Nothing is left anywhere else, because nothing was ever anywhere else.

Third parties

None. The app contains no analytics kits, ad networks, attribution services or third-party libraries that send information anywhere. We share no data with anyone because we hold no data to share.

Purchases and money

The app is entirely free. There are no in-app purchases, no subscriptions, no virtual currency, no wagering and no real money at any point. It is not a casino game: it is educational material about the mathematics of blackjack strategy.

Children

The app collects no data from anyone, and therefore none from children. The age rating on its App Store page reflects its subject matter, not any data collection.

Changes to this policy

If what the app does with your data ever changes, this page will be updated before that change reaches the App Store, and the date above will reflect it.
