Privacy Policy

Adaptive flashcards is designed with a minimal data footprint. We collect only what is necessary to operate, maintain, and improve the App. The categories of information we may collect include:

• Study Progress Data: Cards reviewed, swipe ratings (Easy / Hard), deck completion counts, and scheduled review intervals. This data is stored locally on your device and is not transmitted to our servers.
• App Settings: User-configured preferences such as new cards per day, total cards per day, and instruction page toggle. Stored locally on your device.
• Device & Diagnostic Data: If the App crashes or encounters an error, anonymised diagnostic information (device model, Android OS version, error logs) may be collected automatically via Google Play's crash-reporting service to help us fix bugs.
• Advertising Identifiers: If you have not opted out of personalised advertising, Google's advertising framework may collect the Android Advertising ID (GAID) to serve contextually relevant ads. See Section 4 for full details.

Any information collected is used solely for the following purposes:

• Powering the Spaced-Repetition Algorithm: Your swipe ratings and review history are used exclusively on-device to calculate the optimal next-review date for each flashcard, ensuring the App's core functionality works correctly.
• Improving App Performance: Anonymised crash reports and diagnostic logs help us identify and fix technical issues, improve stability, and enhance the user experience in future updates.
• Delivering Advertising: Advertising identifiers may be used by our third-party ad partners (see Section 4) to display ads within the App. Advertising revenue helps us keep the App free for all users.
• Complying with Legal Obligations: We may use or retain information as required to comply with applicable law, respond to lawful government requests, or enforce our Terms of Use and Disclaimer.

Adaptive flashcards does not sell, rent, or trade any user data to third parties. We may share limited, anonymised information only in the following circumstances:

• Service Providers: Trusted third-party vendors (such as Google Play Services and Firebase Crashlytics) who assist us in operating the App and analysing performance. These providers are contractually bound to use the data only for the purposes for which it was disclosed.
• Ad Networks: Advertising partners such as Google AdMob may receive the Android Advertising ID and related signals to serve ads. These partners operate under their own privacy policies (see Section 4).
• Legal Requirements: We may disclose information if required to do so by law, court order, or governmental authority, or if we believe in good faith that disclosure is necessary to protect the rights, property, or safety of Adaptive flashcards, its users, or the public.
• Business Transfers: In the event of a merger, acquisition, or sale of all or substantially all of our assets, user data may be transferred as part of that transaction. You will be notified via an in-app notice or App Store update description.

The App is free to download and use. To support ongoing development, the App may display third-party advertisements served by ad networks including, but not limited to, Google AdMob. These ad networks may use cookies, SDKs, and advertising identifiers to show ads that are relevant to your interests.

The information collected by ad networks is governed by their own privacy policies. We encourage you to review these policies:

• Google AdMob / Google Ads: policies.google.com/privacy
• Google Play Services: policies.google.com/privacy

All study progress, settings, and preferences generated by using Adaptive flashcards are stored locally on your device. We do not maintain a cloud database of your personal study history.

• On-Device Data: Retained for as long as the App is installed. Uninstalling the App will permanently delete all locally stored data. You may also clear the App's data at any time via Android Settings → Apps → Adaptive flashcards → Clear Data.
• Crash & Diagnostic Logs: Anonymised crash reports submitted to Firebase Crashlytics are retained for up to 90 days, after which they are automatically purged.
• Advertising Data: Advertising identifiers are managed by Google and subject to Google's own data retention policies.

We take reasonable and industry-standard technical and organisational measures to protect any information processed by or through the App from unauthorised access, alteration, disclosure, or destruction.

• Study data is stored in Android's sandboxed internal storage, which is inaccessible to other apps without root access.
• Any diagnostic data transmitted to Firebase Crashlytics is sent over encrypted HTTPS connections.
• The App does not implement user authentication or cloud synchronisation, which substantially limits the attack surface for data breaches.

Depending on your jurisdiction, you may have certain rights regarding your personal information. As Adaptive flashcards stores data primarily on your own device and collects very limited data, many of these rights are exercisable directly by you:

• Access & Portability: All your study data lives on your device. You can inspect it by navigating to the App's internal storage directory.
• Deletion: Clear all App data at any time via Android Settings, or simply uninstall the App.
• Opt Out of Personalised Advertising: Follow the steps in Section 4 to limit ad personalisation or reset your advertising ID.
• Correction: If you believe inaccurate information about you has been collected (e.g., via a crash report), contact us at Adaptive flashcardsdevteam@gmail.com and we will investigate.
• Withdrawal of Consent: You may withdraw consent to this Privacy Policy at any time by uninstalling the App.

Adaptive flashcards requests only the minimum Android permissions required to deliver its core features. The table below explains each permission and why it is needed:

• INTERNET: Required to load advertisements served by Google AdMob and to send anonymised crash reports. The App's educational content (word lists, flashcards) is bundled locally and does not require internet access.
• READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE (Android ≤ 9): Not requested. All data is written to internal app storage only.
• TEXT_TO_SPEECH (implicit): The App uses Android's built-in Text-to-Speech engine to pronounce words aloud. No audio data is recorded or transmitted.
• VIBRATE (optional): Used for subtle haptic feedback during swipe gestures. Can be disabled in Android Settings.

The App may contain links to external websites, app store pages, or third-party content (for example, links to our YouTube tutorial channel or the Google Play Store listing). These external destinations are governed by their own privacy policies.

Adaptive flashcards has no control over and assumes no responsibility for the content, privacy practices, or security of any third-party websites or services linked from the App. We encourage you to review the privacy policy of any third-party site you visit.

We reserve the right to update or revise this Privacy Policy at any time to reflect changes in applicable law, our data practices, or the App's features. Any material changes will be communicated through one or more of the following channels:

• An in-app notification or banner displayed on the App's home screen.
• An updated "What's New" description on the Google Play Store listing.
• An updated "Last Updated" date at the top of this Privacy Policy page.

If you have any questions, concerns, or requests regarding this Privacy Policy or the way we handle your information, please contact us. We aim to respond to all enquiries within 5 business days.
