Question 1

How do I analyze my Google Maps Timeline data?

Accepted Answer

Export your Google Maps Timeline from your Android phone (Settings > Location > Timeline > Export) or use Google Takeout. Then upload the JSON or KML file to Lumo at lumo.lol. The app processes everything locally in your browser — your location data never leaves your device.

Question 2

Is Lumo safe to use with my location data?

Accepted Answer

Yes. Lumo is completely privacy-first. All data processing happens in your browser using Web Workers and IndexedDB. No server receives your data, no accounts are needed, and nothing is uploaded anywhere. Your Google Maps location history stays on your device at all times.

Question 3

What is a location profiler?

Accepted Answer

A location profiler analyzes your location history to identify patterns. Lumo automatically classifies places you visit as home, work, restaurants, shopping, sport venues, or frequent/occasional stops. It builds temporal profiles showing when you visit each place and generates heatmaps and travel analytics.

Question 4

What file formats does Lumo support?

Accepted Answer

Lumo supports Google Maps Timeline JSON files (from Google Takeout or Android export) and KML files. It handles all three Google Timeline formats: semantic segments (newest), timeline objects, and raw location records.

Question 5

Can I use Lumo on my phone?

Accepted Answer

Yes. Lumo has a fully responsive, mobile-friendly interface. You can upload your timeline data, view the interactive map, browse locations, and explore analytics on any modern mobile browser.
