Questioning about the environment var GEO_DATABASE_URL

[Muska-Ami]

The docs seems not give which format of GeoIP db file used, I'm wondering which format does Umami using?

And another question, does Umami download it in start or have a scheduled task update it?

Database format: MaxMind GeoLite2-City in .mmdb format (MaxMind DB binary).

Download timing: At build time via scripts/build-geo.js, not runtime. No scheduled updates—rebuild to refresh.

GEO_DATABASE_URL sources (checked in order):

1. Your custom URL (if set) - supports .tar.gz or direct .mmdb
2. MaxMind official (if MAXMIND_LICENSE_KEY set)
3. Fallback: https://raw.githubusercontent.com/GitSquared/node-geolite2-redist/master/redist/GeoLite2-City.tar.gz

Database saved to /geo/GeoLite2-City.mmdb and loaded at runtime via maxmind package (see /src/lib/detect.ts:104-109).
