This Privacy Policy describes how the mobile application ENside (“the App”, “we”, “us”) handles information when you use it. By using the App you agree to the practices described below.
ENside does not ask you to register an account and does not collect your name, email address, or other directly identifying personal information.
The App stores your learning progress (favourite and known cards, daily usage counters, trial and purchase status) only on your device. We do not have access to this data.
The free version of the App displays advertisements provided by Google AdMob. To serve ads, AdMob may collect and process certain information, including a device advertising identifier (IDFA on iOS), device information, and ad-interaction data.
On iOS, the App asks for your permission through Apple’s App Tracking Transparency prompt before any tracking identifier is used for personalised advertising. You can change this choice at any time in Settings → Privacy & Security → Tracking.
For details on how Google uses data, see Google’s Advertising Privacy Policy.
If you buy the Premium (ad-free) version, the transaction is processed entirely by Apple’s App Store. We do not receive or store your payment details.
We do not sell your personal data. Information processed for advertising is handled by Google AdMob in accordance with its own privacy policy. Purchase processing is handled by Apple.
The App is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal data from children.
Progress data is stored locally on your device and can be removed at any time using the “RESET” option in the App or by uninstalling the App.
Depending on your jurisdiction (e.g. GDPR in the EU, CCPA in California), you may have rights regarding your data. Since we do not store personal data on our servers, most requests can be fulfilled by managing permissions on your device or contacting us at the address below.
We may update this Privacy Policy from time to time. The “Last updated” date above reflects the latest version.
