Welcome to the mobile application operated by Sandi Technologies Niger ("we", "our", or "us"). We are committed to protecting your personal information and your right to privacy. If you have any questions or concerns about this privacy policy or our practices with regard to your personal information, please contact us.
By installing and using our mobile application, you agree to the collection and use of information in accordance with this policy.
We collect a limited amount of data necessary to provide you with educational features, manage your premium subscription, and display advertisements.
A. Automatically Collected Data & Service Providers
We do not host or collect your personal files directly. However, we use trusted third-party services that collect data to perform specific functions:
RevenueCat: To manage, validate, and process your Premium subscription status. RevenueCat collects anonymous transaction identifiers, device receipt data, and subscription history to ensure you retain your premium features across devices.
Google AdMob (Google Ireland Limited): To display advertisements within the free version of the app. AdMob may collect and use device advertising identifiers (such as the Android Advertising ID), cookies, and device telemetry data to serve relevant ads and monitor ad performance.
B. Local Storage (On-Device)
The application uses local secure storage (Hive) on your device to remember your settings (such as your language preference) and your cached Premium status. This data remains strictly on your device.
We use the information collected or processed via our third-party partners for the following purposes:
To enable access to premium features and validate one-time/recurring store upgrades.
To deliver and measure the effectiveness of advertisements (AdMob).
To maintain optimal app performance and troubleshoot technical bugs.
We do not sell, rent, or trade your personal information with third parties. Your data is only shared with service providers explicitly mentioned in this policy (Google and RevenueCat) strictly for fulfilling their operational services under strict privacy terms.
We may also disclose your information where required by law, to comply with legal processes, or to protect the rights, property, or safety of our users and the public.
Since the app does not require a remote personal account system to function, we do not store personal profiles on our servers. Subscription and transactional records are securely managed through the Google Play Store and RevenueCat according to standard security protocols.
We implement appropriate technical and organizational security measures to protect data processed within the application. However, please remember that no method of transmission over the internet or method of electronic storage is 100% secure.
Our application is designed as an educational tool. We do not knowingly collect personal identifiable information from children under the age of 13. If we discover that a child under 13 has provided us with personal information, we will immediately take steps to delete this data. If you are a parent or guardian and are aware that your child has provided personal information, please contact us.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date at the top of this document. You are advised to review this Privacy Policy periodically for any changes.
If you have any questions, feedback, or data requests regarding this Privacy Policy, you can reach out to us at:
