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. The Lumara app 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.
The Lumara website is the one place with an exception, and it is worth stating plainly. To see which pages get read, each page load pings a counter we run ourselves on our own ChronoVerify service. It records the page path and the day, and nothing else: no cookies, no IP address, no browser details, and no identifier of any kind, so nothing links a view to a person. It is not an analytics product and no third party receives the data. The app does not do this; only the website does.
The website also loads its typefaces from Google Fonts, and its ISS video from YouTube once you ask for it. Both are set out under Third parties the website contacts below. Again, neither applies to the app.
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 science 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 and NOAA's servers do log standard web traffic; that data is governed by NASA's privacy policy and NOAA's, not Lumara's.
The website (lumara-space.app) is not entirely self-contained, and it is worth being exact about that:
There are no analytics SDKs, no advertising networks, no social widgets, and no third-party cookies anywhere on the site or in the app.
Lumara is suitable for all ages (Apple rating 4+). Because the app collects no data of any kind, and the website counter records no identifier that could belong to a person, 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.
