What we collect

We collect only what's necessary to run the app: a random device ID (no name or email required), your lesson progress, XP, and streak data stored locally on your device. If you enable push notifications, we store your Expo push token to send daily reminders.

What we don't collect

We never collect your name, email, phone number, or any personally-identifying information unless you voluntarily provide a display name. We don't sell data to third parties. We don't show ads.

Analytics

We use PostHog to understand which features are used and where learners drop off, so we can improve the app. Analytics events are pseudonymised using your random device ID. Analytics is off by default — we only send events if you opt in, and you can turn it off at any time under Settings → Privacy → Analytics.

Crash reporting

We use Sentry to capture error reports when the app crashes. These reports include a stack trace and device type but no personal data. They help us fix bugs faster.

Audio recordings

When you use the pronunciation exercise, your voice is sent to Microsoft Azure Speech Services to transcribe it and score how closely it matches the target phrase. The audio is processed in real time and is not stored by us or by Microsoft beyond the duration of the request.

Voice tutor

The live voice tutor streams your microphone audio to ElevenLabs (Conversational AI) and Microsoft Azure to power the real-time conversation. Audio is processed in real time to generate the tutor's replies and is not retained by us beyond the session.

AI conversations

Roleplay and AI tips are sent to Anthropic's Claude API to generate responses. We do not store conversation history beyond your current session. Anthropic's standard data policies apply.

In-app purchases

Purchases are processed by Apple (App Store) or Google (Play Store) and managed by RevenueCat. We receive only a purchase confirmation and entitlement status — never your payment details.

Data retention

Your progress is stored on your device and also synced to our server so you can restore it on a new device and appear on leaderboards. We keep the minimum needed to run these features (streak, XP, review history, purchases). You can delete your account and all associated server data at any time under Settings → Delete account.

Children

FieldLingo is not directed at children under 13. We do not knowingly collect information from children. If you believe a child has provided personal data, contact us and we will delete it.
