1. Introduction
Welcome to Lection ("we", "our", or "us"). We are dedicated to protecting your personal information and your right to privacy. This Privacy Policy explains what information we collect when you use our mobile application ("Lection"), how we use it, and the rights you have concerning your data.
2. Information We Collect
We only collect data necessary to provide an interactive, structured micro-learning experience:
- Account Information: When you sign up using Firebase Authentication, we collect your email address and a generated unique user identifier (UID). If you sign in via Google, we receive your verified email and display name.
- Learning Progress & Activity: We record your completed lessons, courses unlocked, daily study streaks, earned XP points, quiz responses, and leaderboard participation preferences in Cloud Firestore.
- Purchase & Subscription Receipts: When you upgrade to Lection Pro, your transactions are processed directly by Apple App Store (In-App Purchases) or Google Play Billing. We use RevenueCat to validate your subscription entitlements, expiration dates, and receipt status. We do not receive, process, or store your credit card or financial account numbers.
- Device & Usage Diagnostics: We collect technical diagnostic information including app version, operating system version, and anonymous crash telemetry through Firebase Crashlytics to diagnose technical issues and resolve bugs.
- Advertising Identifiers: On the free tier, we display in-app advertisements via Google AdMob. Subject to your explicit permission via Apple's App Tracking Transparency (ATT) framework on iOS or applicable Android permissions, AdMob may access device advertising identifiers (IDFA/AAID) to serve relevant ads. If you decline tracking permission, only non-personalized ads are requested.
3. How We Use Your Information
Your information is used strictly to:
- Maintain and synchronize your course syllabus progress across devices.
- Calculate learning streaks, XP milestones, and optional public leaderboard ranks.
- Verify Pro access entitlements and prevent velocity lockouts for subscribers.
- Analyze crash logs to continuously improve application stability and performance.
- Comply with applicable legal obligations and enforce our Terms of Service.
4. Third-Party Service Providers
We work with trusted third-party providers who process data in accordance with strict privacy safeguards:
- Google Firebase: User authentication, Cloud Firestore database hosting, and Crashlytics error monitoring.
- RevenueCat, Inc.: In-app purchase verification, customer receipt synchronization, and subscription lifecycle management.
- Google AdMob: In-app ad serving for free-tier users.
5. Data Retention & Account Deletion
We retain your learning history as long as your account remains active. You have full control over your data:
- In-App Deletion: You may permanently delete your account at any time directly in the app by navigating to Settings → Delete Account.
- Effect of Deletion: Initiating account deletion immediately and permanently erases your Firebase Authentication record, user profile, XP points, progress streaks, and all saved learning data from Cloud Firestore. This action is irreversible.
6. Children's Privacy
Lection is designed for general audiences and does not knowingly collect personal identifiable information from children under 13 years of age. If we discover that personal data from a child under 13 has been collected without verified parental consent, we will promptly delete that data.
