Found a bug? Have a question about a NASA wavelength? Want to suggest a feature? Lumara is built and maintained by one person — emails go straight to a real human.
I read every email. Replies usually come within 24 hours.
Nothing. Lumara does not collect, store, or transmit any personal data. There are no analytics SDKs, no advertising networks, no crash reporters that contact servers, no tracking pixels, and no accounts.
If you uninstall Lumara, all of this is deleted with the app. Apple's standard iOS app sandbox isolation applies.
Lumara makes anonymous, unauthenticated HTTPS requests to public NASA endpoints to load real-time solar imagery, moon phase imagery, and space weather data:
These requests carry no identifying information. They look identical to opening one of those URLs in a web browser. NASA's servers do log standard web traffic; that data is governed by NASA's privacy policy, not Lumara's.
Lumara is suitable for all ages (Apple rating 4+). Because Lumara collects no data of any kind, it complies with COPPA, GDPR-K, and equivalent regulations by default.
If anything material changes, this page will be updated and the change date will appear in the footer below.
NASA's imagery sometimes has brief outages or maintenance windows, especially on the SDO and SOHO instruments. If an image looks frozen, pull-to-refresh on the Sun tab usually fixes it. The timestamp under each image shows the actual capture time from the spacecraft.
The 4K timelapse videos are large. On older devices with slower connections, switching to a lower wavelength resolution in Settings → Default Resolution can help.
Moon phase calculations work fully offline (the math is pure Dart, runs on-device). Live imagery requires internet — there is no NASA imagery cached for offline viewing.
Not currently. The code is private. The data sources Lumara uses are all freely available — anyone can build their own viewer.
NASA does not endorse Lumara. All NASA imagery used in Lumara is in the public domain per NASA's media usage guidelines.
