Privacy Policy
How Lanter handles your data.
Last updated: July 12, 2026
Lanter works fully offline, with no account required.
Your tasks, courses, and notes are stored on your device by default.
No analytics, tracking, or advertising of any kind.
We never sell, rent, or share your personal data.
If you choose to sign in, your tasks and courses are backed up to a secure cloud service (Supabase) solely so you can restore them and use them across devices. That's the only reason cloud storage exists.
What stays on your device
Tasks, courses, notes, deadlines, reminders, preferences, and all atmospheric and personalization behavior. If you never sign in, no personal data ever leaves your device.
What's stored in the cloud (only if you sign in)
- Your email address — used only for sign-in, via a magic link. We never store a password.
- Your tasks, courses, and preferences — used only for backup and cross-device continuity.
Cloud storage and authentication are provided by Supabase on our behalf, protected by security rules so only you can access your own data. We do not store analytics, usage tracking, or behavioral profiles — the atmospheric and personalization layer never leaves your device.
What we do not do
- No analytics or tracking
- No advertising or ad identifiers
- No selling or sharing of personal information
- No behavioral profiling
Your control
- Use the full app without ever creating an account.
- Sign out at any time — your local data stays intact.
- Delete your account and cloud data in-app whenever you'd like. Local data remains unless you also clear the app.
- Export your data, if and when this becomes available.
Children's privacy
Lanter is intended for students and general audiences. We do not knowingly collect data from children under the legally required age in their region.
Data security
We use industry-standard encryption and access rules, and we collect as little as possible by design.
