Privacy Policy

1. Data We Collect Directly

None. Idoneo does not require an account, email, or any personal information. All study data — FSRS scheduler state, quiz results, preferences, and downloaded banks — is stored exclusively on your device using local storage.

2. Third-Party Services

Idoneo uses Google Firebase services solely for crash reporting (Crashlytics), anonymous usage analytics (Analytics), and push notifications (Cloud Messaging). These services collect anonymous, aggregated data such as crash traces and device model. No personal identifiers are involved. Google Play Billing processes purchases — Idoneo never sees payment data.

3. What We Do NOT Collect

• No name, email, or phone number
• No account or password
• No location data
• No advertising ID
• No browsing history
• No data shared with third parties

4. Data Retention & Deletion

All study data is retained locally until you clear app data or uninstall. Firebase logs are retained per Google's standard policies (90–365 days). To delete all data: Android Settings → Apps → Idoneo → Clear Data.
