Privacy Policy

What data we collect

FluentCards uses Firebase Authentication (Google sign-in) to manage accounts. We receive your email address and display name when you sign in with Google. We do not store passwords — Google handles that.

Your flashcard data (decks, cards, review history) is stored in Firebase Firestore and is only accessible to you unless you choose to publish a deck to the marketplace.

How we use your data

• To authenticate you and keep your data private
• To sync your flashcards across devices
• To enable the community marketplace (shared decks only)
