Effective date: August 11, 2026
This policy explains how "1A2B — Bulls & Cows" (the "app") handles your data. In short: the app is an offline game. We do not collect or upload any personal data ourselves; the only third party that touches data is the advertising service.
The app requires no account and has no server. Your games, notes, statistics, streaks and preferences are stored only on your device; deleting the app deletes them all. We cannot read or upload this data.
The free version shows banner, interstitial and rewarded ads served by Google AdMob. To serve and measure ads, Google may collect device identifiers (such as the advertising ID), IP address, coarse location and ad-interaction data.
The one-time "Pure" purchase removes banner and interstitial ads. Purchases are processed by Apple's App Store; we never receive your name, address or payment details. Your device only stores the fact that the purchase was made.
The app is not directed at children under 13 and does not knowingly collect personal data from children.
Because everything lives on your device, retention is up to you — delete the app or reset it in settings to erase all data.
If we make material changes, we will update the effective date on this page. Continued use of the app means you accept the updated policy.
