Last updated: April 7, 2026

twentythree Dev ("we", "us", or "our") builds and publishes mobile applications.

1.2 Data Collected by Third-Party Services

Our apps may use the following third-party services that could collect information used to identify you:

• Google AdMob: Used to display advertisements. AdMob may collect device identifiers, IP address, and usage data to serve personalized or non-personalized ads. See Google's Privacy Policy.

4. Data Storage and Security

• We do not have access to your personal data
• Data is protected by your device's built-in security features
• If you uninstall the app, all locally stored data will be permanently deleted

Our apps do not use "cookies" explicitly. However, apps may use third-party code and libraries that use "cookies" to collect information and improve their services. You have the option to either accept or refuse these cookies and know when a cookie is being sent to your device.

7. Your Rights

• Delete: You can delete your data within the app at any time. Uninstalling the app removes all locally stored data.

• Ads: Where available, you can purchase a premium version to remove advertisements.

8. Children's Privacy

Our apps are not directed at children under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we will immediately delete it. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we can take necessary action.
