Summary
Book Move does not collect any personal data. It is a blackjack basic-strategy trainer built by Materia Labs LLC. There are no user accounts, no ads, no analytics or tracking, no third-party data sharing, and no in-app purchases.
Information We Collect
None. Book Move does not ask for, collect, or transmit any personal information to Materia Labs. We have no servers that receive your data and no way to identify you.
Your Practice Data
The hands you play and your accuracy history are stored locally on your device so the app can show your stats and heatmap.
If you enable iCloud, this history syncs across your devices through your own private iCloud account. That data is handled entirely by Apple under your Apple ID — it is never sent to, stored by, or visible to Materia Labs. You can delete it at any time from within the app (Settings → clear history) or by removing the app's data from your iCloud account.
Analytics & Tracking
Book Move contains no analytics, no advertising identifiers, and no third-party tracking SDKs. It does not use the Advertising Identifier (IDFA) and does not track you across apps or websites.
Children's Privacy
Book Move does not collect data from anyone, including children. The app is rated for a mature audience because it depicts card-game content, but it involves no real-money play.
Changes to This Policy
If Book Move ever changes how it handles data, we will update this page and revise the date above.
