Privacy

This map has no accounts, no ads and no tracking cookies.

Map settings. The map remembers your last mode, layers and view in your browser's local storage so it opens where you left off. That data stays on your device; clear it with your browser's site settings.
Your location. If you tap the locate button, your browser asks before sharing your position, and the position is used only on the page to center the map. It is not sent anywhere.
The Ask guide. When you ask a question, the question and the map records for the spot you tapped are sent to the site's server, which passes them to Anthropic’s Claude API to write the answer. The site does not store your questions or the answers. Cloudflare and Anthropic process these requests under their own privacy policies. Please don't put personal details in a question.
Analytics. The site runs no analytics or tracking scripts.
Hosting. The site runs on Cloudflare, which keeps standard request logs for security and reliability.
Club edition. Members sign in through Cloudflare Access with their email address. It is used only to let members in.
Email. If you write to hello@historyunderfoot.org, your message is used to answer you and fix the map, and is never shared or sold.
