Nabluna ("we", "the app") is built to respect your privacy. The core principle: your observation data never leaves your device. This policy explains what is and isn't collected.
The following is stored locally on your device and is never transmitted to any server:
You can erase all of this at any time from Settings → Clear data, or by uninstalling the app.
Location is optional. You can enter a city manually instead of granting location permission.
Nabluna does not collect:
Nabluna contains no ads and does not sell or share personal data.
| Permission | Why | Required? |
|---|---|---|
| Location (coarse/fine) | Compute the sky view for your position; a rounded position fetches local weather | No manual entry available |
| Camera | Live AR sky overlay | No sensor-only mode available |
| Internet | Local weather, satellite and space station positions, optional online imagery | No core sky view works offline |
| Notifications | Local reminders for celestial events | No can be turned off |
| Vibrate | Haptic feedback on discovery/level-up | No app works without it |
Nabluna offers optional one-time purchases via Google Play Billing: cosmetic themes (e.g., Aurora, Nebula, Gold, Deep Space, Solar Flare, Ice Giant, Supernova, Midnight Ops), a Platinum Bundle, and feature packs (The Scientist Package, The Ambient Pack, The Observer Pack, and Nabluna Complete) that add extras such as an observatory console, ambient soundscapes, and star catalog overlays. These are processed by Google Play; we receive only a record of which product you purchased (to unlock it). Purchase data is handled by Google under its own privacy policy. No payment information is collected by us.
The core sky experience is free. Achievements and progression are earned by observing, never by paying.
Nabluna is designed for stargazers of all ages, including children. We do not knowingly collect personal information from anyone, including children. There are no accounts, ads, analytics, or tracking, and your observations, photos, and journal stay on your device.
Location is optional, and you can enter a city manually instead. When used, it computes the sky view and fetches local weather using a rounded, approximate position. It is never stored or shared. Camera images for the AR sky view are processed on the device and never uploaded.
In-app purchases are handled by Google Play, which offers parental purchase controls. We recommend parental supervision when children use the AR sky view.
If you believe a child has provided personal information, contact [email protected] and we will delete it.
With your permission, Nabluna can send local notifications reminding you of upcoming celestial events (e.g., a meteor shower peaking tonight). Notifications are delivered locally on your device. You can disable them at any time in Settings, and the app asks before enabling them on first use.
We may update this policy. Material changes will be reflected by the effective date above and, where appropriate, in-app notice.
