Privacy Policy for Mukhin Flashcards
Last updated: October 7, 2026.
About the app
Mukhin Flashcards (called Flashcards in the interface) helps you create flashcards, organize them into decks, and review material. This policy describes the app on Android, iOS, desktop, and in a browser.
Developer: Mukhin. Privacy contact: mukhin.support@gmail.com.
Data the app uses
The app stores your flashcards and decks, study progress, and preferences. This includes flashcard text, deck names, relationships between them, learned status, answer counts, the time of the last review, your language, theme, and study preferences.
This data is needed to provide the app’s features. It stays on your device. In the web version, it is stored in your browser’s storage for the app’s site. Files you select for import are processed locally. Flashcards may contain personal information if you enter or import it yourself.
The app has no account registration, server storage for flashcards, or synchronization between devices. Flashcards, study progress, and preferences are not sent to the developer. The app uses no advertising, analytics services, or its own crash-reporting service. The developer does not sell your flashcard content.
When data may leave your device
Backups. Your operating system, browser, or backup tools you choose may copy local data to the cloud or transfer it to another device. System backup is enabled in the Android app. Backup capabilities, protection, and retention depend on the platform, service, and your settings. The developer does not gain access to these backups through the app.
Export. When you choose to export, the app creates a JSON file containing flashcards and decks. Study progress and preferences are not included. You choose where to save the file or whom to share it with. Choosing cloud storage or sending the file to someone else may transfer it off your device. The app does not encrypt exports.
Web version and links. Your browser contacts the web server when loading or updating the web app or opening website links. The web server may record technical request information in logs, including your IP address, request time, the address of the requested resource, and browser details. Whether these logs are stored and how long they are retained depend on the web server settings. This applies only to website visits and use of the web version. The installed Android, iOS, and desktop apps do not send these usage statistics to the web server. Flashcard content, study progress, and app preferences are not included in these requests. The website uses no analytics services or visitor counters.
System services. Your operating system, app store, and browser may independently process diagnostic information under their settings and policies. App stores may provide system stability reports to the developer. This is separate from the app’s own analytics.
Retention, protection, and deletion
The app uses local device or browser storage without additional encryption of its own. Protection depends on the platform, access to your device, and backup settings. Use a device screen lock and share exports only with recipients you trust.
Data remains until you delete it. You can edit and delete flashcards and decks in the app. Deleting a flashcard deletes its study progress. Deleting a deck keeps the flashcards themselves.
To delete all local data:
- On Android, clear the app’s storage in system settings.
- On iOS, delete the app and its data. Offloading the app keeps its data.
- In the web version, clear the site’s data in your browser. This removes the app’s data in that browser profile.
- On desktop, delete the app’s local data files. Uninstalling the app does not necessarily remove these files. For help, contact support and specify your platform.
Deleting local data does not delete exports or previous backups. Manage these separately. Restoring a backup may bring back deleted data. The developer cannot remotely view or delete your local flashcards through the app.
Contact and policy changes
If you contact support, you voluntarily provide your sender address and message content, including any attachments you add. We use this data to respond to and resolve your inquiry. Correspondence is stored in Gmail for as long as needed to handle your inquiry and provide follow-up support. You can request deletion of the correspondence by emailing mukhin.support@gmail.com. Please do not send flashcards or other personal information unless needed for your inquiry.
If our data practices change, we will update this policy and the date at the top. Current versions: English and Russian.
