This Privacy Policy should be read together with our Terms of Use, which outline the rules for using the Cardera app.
Cardera (“we,” “our,” or “us”) is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our app.
We do not collect personal data or precise location.
Local App Data:
Your app progress (e.g., liked cards, completed decks) is stored on your device. This data is not transmitted to us or third parties, except for optional analytics data that you consent to share for app improvement.
Premium Purchases:
Payments for Premium features are processed securely by the app store platform you use (such as Google Play or the App Store). We do not receive or store your payment details. We only receive confirmation that a purchase was successful to unlock Premium features on your device.
Analytics (Optional):
If you give consent, Cardera may use Firebase Analytics, a service provided by Google, to collect anonymous and aggregated usage data.
This helps us understand how the app is used (for example, which decks or features are most popular) so we can improve user experience.
We do not collect any personal information such as your name, email, or precise location.
You can choose whether to enable or disable analytics at any time within the app’s analytics settings.
When enabled, data is processed by Google as our service provider under its Privacy Policy and Firebase Terms of Service.
Data Sharing:
We do not sell, rent, or share any information with unrelated third parties.
Aggregated analytics and store-provided metrics (e.g., installs, crash rates) are used solely for app performance and improvement purposes.
Cardera may use third-party libraries or services as part of the app’s functionality. These services may have their own privacy policies. We do not use them for personal data collection and are not responsible for their practices.
All app data is stored locally on your device.
Deleting the app will permanently remove this data.
If you have enabled analytics, you can turn it off anytime in the app’s analytics settings.
Cardera is not directed to children under 13, and we do not knowingly collect any information from children.
We may update this Privacy Policy from time to time.
