Google's Privacy Policy
AdMob Partner Policy
Numbera is intended for a general audience. We do not knowingly collect personal information from children under 13. The app uses non-personalized ads where required by applicable law (such as COPPA in the United States).
If you believe your child has provided personal information through this app, please contact us and we will address it promptly.
The only third-party service integrated in Numbera is Google AdMob. No analytics platforms, social SDKs, or data brokers are used.
Since HappyLeaf Studio does not collect or store any user data on external servers, there is no data retention on our end. Any data collected by AdMob is governed by Google's own retention policies.
Depending on your region, you may have rights regarding personal data including access, correction, or deletion. Since we do not hold any personal data ourselves, any such requests related to ad data should be directed to Google.
You can manage your ad preferences and data directly through your Google account or Android device settings.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated effective date. Continued use of the app after changes constitutes acceptance of the new policy.
