Last updated 2026-08-22.

Blackjack Lab does not require an account and does not collect personal information directly. Some pages may display advertising, described below.

What is stored, and where

Your selected table rules, your chosen bet amount, and your session statistics (hands played, hands correct, decision cost) are stored only in your browser’s local storage. This data never leaves your device and is not sent to any server.

Advertising and cookies

Blackjack Lab may display advertising served by Google AdSense. Google and its advertising partners may use cookies, device identifiers, or similar technologies to serve ads based on your prior visits to this or other websites, and to measure ad performance.

You can review or turn off personalized advertising at Google’s Ads Settings, read how Google uses data from sites that use its services in Google’s advertising policy, or opt out of personalized ads from other participating providers at aboutads.info.

Advertising cookies are set and controlled by Google and its partners under their own privacy policies, not by Blackjack Lab. Blackjack Lab itself does not sell or share your personal information with advertisers.

Clearing your data

Clearing your browser’s site data for this page, or using a private/incognito window, removes all locally stored Blackjack Lab data.

Changes

If Blackjack Lab later adds optional accounts or server-side history, this page will be updated to describe exactly what is collected and why.
