Frequently Asked Questions

1. What is the FSRS algorithm and how does it work?

LinguaCue uses the modern Free Spaced Repetition Scheduler (FSRS) algorithm, a state-of-the-art memory model that predicts when memory decay is about to occur. When you rate cards as Again, Hard, Good, or Easy, the system calculates personalized review intervals to maintain 90–95% long-term recall with minimal study time.

2. How do I switch between Japanese, Spanish, German, and French?

In the top bar of the Today screen, simply tap the language selector pill (e.g., 🇯🇵 Japanese) to open the track selector drawer. You can switch tracks instantly. Each language maintains its own independent decks, daily quotas, and retention stats.

3. Can I study offline without an internet connection?

Yes, 100%. All vocabulary cards, example sentences, and core audio cues are stored locally in the on-device database. You can review cards on airplanes, trains, or in subway tunnels without any data connection. Your review history will sync automatically when you reconnect to Wi-Fi or cellular.

4. How do I restore my purchases or LinguaCue Pro subscription?

If you reinstalled the app or set up a new device, open LinguaCue, tap the Settings icon (or open the Pro Paywall), and tap "Restore Purchases". As long as you are signed into the same Apple ID or Google Play account, your Pro features will activate immediately.

5. How do I sync between my iPhone and Android phone?

To sync across platforms:

  1. Go to Settings → Cloud Account in LinguaCue.
  2. Sign in with your email address or Google account on both devices.
  3. Your review queues, streaks, and custom settings will synchronize in real-time via Cloud Firestore.

6. How do I delete my account or reset my learning data?

You have full ownership of your data:

  • To reset study stats while keeping your account: go to Settings → Reset All Learning Data.
  • To delete your cloud account and all associated data permanently: go to Settings → Delete Account or visit our Account Deletion Portal.
