Privacy
What we collect
- An opaque account identifier; sign-in via Apple or Google. Your email is contact metadata only and never merges or binds accounts.
- The vocabulary items you create or import, your language settings and level.
- Bounded learning events (five kinds). No conversation content — transcript-shaped data is refused at the wire.
- Integration records and hashed credentials. Raw tokens are never stored.
What we never collect
Conversations with your AI assistant, prompts, provider credentials, payment data.
Telemetry and retention
Infrastructure invocation logs only (name, timing, status), retained 30 days. Account data persists until you delete it.
Your rights
Export your complete account as one document at any time. Delete your account entirely — including the sign-in principal — from the app. Revoke any connected integration immediately.
