Privacy Policy

This Privacy Policy describes how LingoFlash ("we", "us", or "our") collects, uses, and protects your information when you use the LingoFlash mobile application and website (the "Service").

By using LingoFlash, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

a. Data stored on your device

LingoFlash stores the following data locally on your device only, using your device's built-in storage. This data never leaves your device and is never transmitted to our servers:

• Your selected native language and the language you are learning.
• Your lesson completion progress (which cards you have marked as done).
• Your daily learning streak count.
• Your favorite lessons.
• Your preferred speech speed setting.
• Whether you have completed the onboarding screens.

b. Text-to-speech (pronunciation feature)

When you tap the speaker icon on a flashcard, LingoFlash uses your device's built-in text-to-speech engine (Apple's AVSpeechSynthesizer on iOS, Google TTS on Android) to read the phrase aloud. This uses the native engine on your device and works fully offline. No phrase text is sent to our servers. On some Android devices, the TTS engine may contact Google's servers — this is governed by Google's own privacy policy.

c. Contact information (optional)

If you contact us by email, we collect only the information you voluntarily provide (your name, email address, and message content) in order to respond to your enquiry.

d. What we do NOT collect

• No name, email address, or any account information.
• No location data.
• No device identifiers or advertising IDs.
• No crash logs or analytics (unless you have granted permission to your OS to share diagnostics with developers).
• No payment information (the app is free).

2. How We Use Your Information

Since we collect no personal data, there is no data to use for marketing, advertising, or profiling purposes. The data stored locally on your device is used solely to:

• Remember your language preferences between sessions.
• Track your learning progress and streak so you can see how far you have come.
• Save your favorite lessons for quick access.
• Restore your settings when you reopen the app.

3. Legal Basis (GDPR)

LingoFlash does not process personal data as defined by the GDPR, as we do not collect any identifying information. The data stored locally on your device is processed by your device's operating system, not by us. If you contact us by email, we process your contact data based on your consent and our legitimate interest in responding to your enquiry.

4. Data Sharing

We do not sell, rent, or share your data with any third parties, because we do not collect any personal data. The only third-party services involved are:

• Apple App Store / Google Play Store — used to distribute the app. Their own privacy policies govern any data they collect during download and installation.
• Google Fonts — the app uses the Nunito font, which may be loaded from Google's servers on first use if a local copy is not cached. Only font file requests are made — no personal data is sent.
• Device TTS engine — as described in section 1b above, phrase text is passed to your device's native TTS engine for pronunciation. On Android this may involve Google's servers.

5. Data Retention

All data is stored locally on your device and remains there until you delete the app. Deleting LingoFlash from your device removes all locally stored progress, settings, and preferences. We hold no copy of this data on any server.

If you contacted us by email, we retain that correspondence for as long as necessary to resolve your enquiry, after which it is deleted.

6. Your Rights

Because we do not collect personal data, most data subject rights under GDPR and similar laws do not apply in the traditional sense. However:

• Access and deletion of your progress data — you can reset all progress by deleting and reinstalling the app at any time.
• Contact data — if you have emailed us, you may request that we delete your correspondence by contacting us at the address below.
• Complaints — you have the right to lodge a complaint with your local data protection authority.

7. Security

Your progress data is stored using your device's standard local storage mechanisms (SQLite and SharedPreferences), which are protected by your device's own security model including device encryption and app sandboxing. We do not transmit this data, so there is no risk of it being intercepted in transit.

8. Children's Privacy

LingoFlash does not collect any personal data from any users, including children. The app contains no advertising, no account creation, and no social features. We consider it appropriate for all ages. Parents can allow children to use LingoFlash without concern about data collection.

9. International Transfers

We do not transfer personal data internationally because we do not collect personal data. Your device's local storage stays on your device, wherever you are in the world.

10. Changes to This Policy

We may update this Privacy Policy from time to time, for example if we add new features that involve data collection. The "Last updated" date at the top of this page indicates the latest revision. Continued use of the app after changes constitutes acceptance of the updated policy.
