How Blackjack Index handles browser-local information in this educational product.

Last updated
Scope
Browser-local product data and future optional services.

Blackjack Index has no accounts, deposits, withdrawals or server-side player profiles. Before you choose, settings, learning progress and virtual bankroll data stay in page memory only; if you allow optional local storage, those records can remain in this browser.

Microsoft Clarity is the only external measurement vendor. It loads only after analytics consent, receives no advertising-storage permission and is disabled when measurement is rejected or Global Privacy Control is detected.
