Website privacy
This covers the website lightglance.app and its beta waitlist. For the app, see the Lightglance privacy policy. Short version: this site keeps your email address only if you join the beta, uses it only to invite you, and keeps nothing else about you.
The waitlist
If you join the TestFlight beta, we store your email address, the language you chose and the time you signed up. We use it to send you an invite to the LightGlance beta, and nothing else. We don’t share it or sell it.
It is stored with Cloudflare, which hosts this site. To have it deleted, write to hello@lightglance.app and it’s gone.
Your location
To show sun times for where you are, Cloudflare estimates your city from your internet address. We round it to about a kilometre, use it to answer that one request, and don’t store it. If you tap the location button, your browser asks before it shares your precise position, and that stays in your browser.
No tracking
No cookies, no analytics, no ads. Fonts are served from this site. The aurora forecast comes from NOAA through our own server, so your browser doesn’t contact anyone else.
