Privacy Policy for FlipDeck

June 19, 2026

This Privacy Policy explains how FlipDeck ("the App", "we", "our") handles your information. We are committed to protecting your privacy. Please read this document carefully.

1. Overview

FlipDeck is an offline flashcard study app. The App allows you to create decks of flashcards, add front/back cards, study them with an animated flip-and-grade flow, track per-deck mastery and a spaced-repetition queue, maintain a daily study streak, and search across all of your cards. The App is designed with an offline-first approach: all personal data you enter is stored exclusively on your device and is never transmitted to our servers.

2. Data We Do NOT Collect

We do not collect, store, or transmit any of the following:

• Personal identification information (name, email, phone number, etc.)
• Account credentials or authentication tokens
• Device location or GPS coordinates (no location permission is requested)
• Usage analytics, crash reports, or behavioral telemetry
• Advertising identifiers or tracking cookies
• The content of your decks, flashcards, or study history

3. Data Stored Locally on Your Device

The following data is stored only on your device using Android's Room database and DataStore, and is never sent to any external server:

• Decks: deck name, color tab, created date, last studied date.
• Cards: front (question) text, back (answer) text, spaced-repetition box level, times seen, and last reviewed time.
• Study progress: day streak, cards reviewed today, and the last day you studied.
• Preferences: theme (Light/Dark/System), daily card goal, default shuffle setting, and whether the answer side shows first — stored via Android DataStore.

All locally stored data remains under your full control. You may delete individual cards or whole decks from the deck editor, reset all study progress from Settings, or uninstall the App to remove all data permanently.

4. Third-Party Services — None

The App does not communicate with any third-party services. All functionality works offline. This section does not apply.

5. Permissions

The App does not request any runtime permissions. It functions entirely offline and does not require INTERNET, location, camera, contacts, or notification permissions.

The App does NOT request:

• Location (GPS, coarse, background)
• Contacts
• Phone state or identifiers
• SMS or call log access
• Internet access

6. No Advertising or Analytics SDKs

FlipDeck does not integrate any advertising networks, analytics SDKs (such as Firebase Analytics, Crashlytics, Amplitude, Mixpanel, or similar), or third-party tracking libraries. There are no ads of any kind within the App.

7. Children's Privacy

The App does not knowingly collect any personal information from children under the age of 13. Since the App collects no personal information from any user, it is safe for use by all ages.

8. Data Security

Because all user-generated data is stored locally on your device, the security of that data depends on the security measures provided by the Android operating system and your device (screen lock, encryption, etc.). We do not control how Android handles on-device storage security, but we do not expose any data to external parties.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in an updated version of this document bundled with a new App release. The "Last updated" date at the top of this page will be revised accordingly. Continued use of the App after an update constitutes acceptance of the revised policy.
