Our approach
Saved place IDs, day numbers and order are stored in localStorage on your device. There is no account, cloud sync, public sharing or analytics provider in this edition. Clear the trip in My trip or clear browser storage to remove it. A configured map may request tiles from its named provider only after you load it; the provider can receive ordinary network data such as your IP address. Hosting and delivery providers may retain operational logs under their own policies; production legal review is pending.
