Privacy Policy
The short version
Lantyrn is a fully offline app. You record a short voice note, the app reads the mood and turns it into a glowing orb — and every bit of that happens on your device. There are no user accounts, no servers, and no analytics. Nothing you create ever leaves your phone. The app works in airplane mode, by design.
Data you create in the app
Your check-ins — the orbs, their colors, and your history — are stored locally on your device in an on-device SQLite database. There is no cloud sync and no backend I operate, so I have no ability to see or recover this data. If you uninstall the app, this data is gone.
Voice notes & on-device processing
When you record a voice note, the audio is transcribed and analyzed entirely on your device using Apple's on-device speech recognition. The result is mapped to an orb. The audio and transcript are not uploaded anywhere — there is no network call involved at any point in this flow.
What the app does not collect
- No analytics. No usage tracking, no event telemetry, no product-analytics SDK.
- No crash reporting. No third-party diagnostics service.
- No user accounts, no sign-in, no email collection.
- No advertising, no ad networks, no third-party trackers.
- No selling, sharing, or licensing of any data — there is no data leaving the device to share.
Notifications
Lantyrn does not send remote push notifications. Any reminders are scheduled locally on your device; no notification data leaves your phone.
Permissions
- Microphone — so the app can listen to your voice note and read the inner weather of the moment. The audio is processed on your device and is not stored or transmitted off it.
- Add to Photos — only if you choose to save your orb as a live-photo wallpaper, the app writes that image to your photo library. The image stays on your device.
The app does not request camera, location, or contacts access.
Children
The app is not directed at children under 13 and I do not knowingly collect data from them. (In practice, the app collects nothing at all.)
Your choices
- Revoke microphone or photo access at any time from iOS Settings → Lantyrn.
- Delete everything by uninstalling the app.
Changes
If I change this policy, I'll update the date at the top and, for material changes, surface a notice in the app on next launch.
