M&G Devs ("we," "us," or "our") operates the mobile game One Bullet (the "App"). This Privacy Policy explains what information the App collects, how it is used, and your choices.
One Bullet is directed at a general and family audience, including children. This policy is written to comply with the Children's Online Privacy Protection Act (COPPA) and the Google Play Families Policy.
One Bullet does not require an account, login, or sign-up. We do not collect:
All gameplay data (high scores, unlocked weapons, settings, purchase entitlements) is stored only on your device using local storage (Hive), and is never transmitted to us.
Because the App is free to play and supported by ads and optional in-app purchases, it uses the following third-party services, which may automatically collect limited technical data:
The App shows rewarded, interstitial, and banner ads through Google AdMob. AdMob may collect device and usage information (such as device type, operating system, general location derived from IP address, and ad interaction data) to serve and measure ads and to prevent fraud.
Because the App is marked as child-directed, ads are served in a manner consistent with the Google Play Families Policy: no personalized/behavioral advertising is shown, and data collection for advertising purposes is limited accordingly.

The App uses Firebase Analytics (a Google service) to understand aggregate, non-identifying usage patterns, such as which screens are viewed or how long sessions last, so we can improve the game. Analytics collection is configured to be appropriate for a child-directed app — for example, advertising identifiers and ad-personalization signals are not collected from users of this App.

One Bullet offers optional purchases (e.g., "Remove Ads," skin packs) through Google Play Billing. All payment information is handled entirely by Google Play — we never receive or store your payment details. Google may collect purchase history to process transactions.

Any information collected by the third-party services above is used only to:
We do not sell any information, and we do not use it to build advertising profiles of individual users.
We are committed to protecting the privacy of children. One Bullet does not knowingly collect personal information from children. Because the App may appeal to children under 13:
If you are a parent or guardian and believe your child has provided us with personal information, please contact us at the email above and we will take steps to address it.
We do not share information with third parties except:
Gameplay data stored locally on your device (Hive) remains until you uninstall the App or clear its data. Data collected by AdMob, Firebase, and Google Play is retained according to Google's own retention policies, linked above.
We take reasonable measures to protect information within our control. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
If you access the App from outside your country of residence, your information (as described above) may be processed in other countries, including the United States, by our service providers.
We may update this Privacy Policy from time to time. Changes will be posted at this same location with an updated "Last updated" date. Continued use of the App after changes constitutes acceptance of the revised policy.
