Privacy Policy
Blackjack Strategy is a basic strategy trainer. It deals practice hands and tells you whether you picked the correct action. It does not involve real money, betting, or gambling of any kind. This policy explains what information the app handles and why.
Information you provide
None. The app has no accounts, no sign-in, and no forms. It never asks for your name, email address, or any other personal details.
Information stored on your device
Your practice statistics, such as streaks and per-hand accuracy, and your settings are saved only on your device. They are never uploaded anywhere. You can erase them at any time with "Reset All Statistics" in the app's Settings, or by uninstalling the app.
Advertising
The app is free and supported by ads. Ads are served by Google AdMob, a service of Google LLC. To deliver and measure ads, the Google Mobile Ads SDK inside the app automatically collects:
- Your device's advertising ID and app set ID.
- Your IP address, which may be used to estimate your approximate location.
- Interactions with ads and the app, such as app launches and ad taps.
- Diagnostic information about the app's and the SDK's performance.
Google uses this information for advertising, analytics, and fraud prevention. It is transmitted using encryption in transit. DINKdev LLC does not receive or store this information itself, and does not sell it. How Google handles it is described in Google's Privacy Policy and in How Google uses information from sites or apps that use our services.
Your choices
- You can reset or delete your advertising ID, and opt out of ads personalization, in your device's settings under Google, then Ads.
Children
The app is not directed at children under 13, and we do not knowingly collect information from them.
Changes
If the app's data practices change, this page will be updated and the date at the top revised.
