Privacy
The short version: we read what a trip needs, and nothing else.
What signing in gives us
Your name and email address from Google. No advertising profile is built from them, and they are not passed on.
Your library stays yours
Photos live on your server. We read timestamps and coordinates, upload nothing.
When a model is called
Only over the material of the trip you are in, and only when you ask for it. There is no profile and no personalisation store, and calendar event titles never reach a model — only busy intervals do.
Who else sees a question
Weather, maps, routing, place and flight lookups go to third-party services — Open-Meteo, OpenStreetMap and OSRM, Foursquare, AviationStack. They receive the coordinate or flight number being looked up, not your account.
Leaving
Every trip exports whole. If we ever stop, you keep the notebook.
