Privacy policy

Who we are
SkyFlux is made by Täisühing Nordic Moonlight, registry code 11234439, Estonia. For anything in this policy, write to support@nordicmoonlight.com.
What leaves your device, and where it goes
| What | Sent to | Why |
|---|---|---|
| Approximate location — coordinates rounded to one decimal place (a cell of roughly 60 km²; your street or home cannot be identified from it) | Open-Meteo | The cloud-cover forecast for your night sky |
| The same rounded location | BigDataCloud | Showing a place name (e.g. your town) instead of raw coordinates |
These requests carry no identifiers — no account, no advertising ID, no device fingerprint. Like every internet request they expose an IP address to the service that answers them; we attach nothing to it.
The app also reads public astronomy and space-weather feeds — NOAA SWPC, NASA SDO, CelesTrak. These are plain downloads in the other direction: no data about you is sent to them at all.
What never leaves your device
- Your precise position. The GPS coordinates the sky calculations use stay on the phone. Only the rounded cell described above is ever transmitted.
- The camera view. The AR sky view draws star positions over a live camera image. Frames are rendered to your screen and thrown away — never recorded, stored or sent.
- Sensor data (compass, gyroscope) — used on the device to know where you point.
- Your settings and language — stored in the app's local storage on the device.
- Notifications. Meteor-shower, eclipse and full-moon reminders are computed and scheduled entirely on the device.
What we store on our servers about you
Nothing. SkyFlux has no user accounts and no server-side database of users. There is consequently nothing for us to sell, share, or lose — and nothing to delete on request, though you are welcome to write and ask.
The version of the app distributed outside the app stores checks our file storage for a newer version when you open it. That request carries no personal data. Versions installed from Google Play or the App Store do not include this mechanism.
Permissions the app asks for
| Permission | Used for |
|---|---|
| Location | Computing what your sky looks like from where you stand, and the two requests above. Optional — you can pick a place by hand instead. |
| Camera | The AR sky view only. Optional. |
| Motion sensors | Pointing the sky map where you point the phone. Optional. |
| Notifications | Locally scheduled astronomy reminders you switch on yourself. Optional. |
Children
SkyFlux is suitable for a general audience and collects no personal data from anyone, children included.
Changes to this policy
If the app ever starts doing more than is described here — for example an optional aurora-alert service — this page will say so plainly before that version ships, and the date at the top will change.
