Privacy policy
SHIZUAN has no accounts and no forms. We do not ask for your name, email address or any other personal details. This page explains what does happen when you use the site.
Handled only on your device
- Map links and coordinates you paste. The search box pulls the latitude and longitude out of the text inside your browser and finds the matching neighborhood. The link itself is never sent to our server or stored.
- Your location. Only used if you press “My location” and your browser grants permission. It is used in the browser to open the matching neighborhood; the coordinates themselves are neither sent nor saved. The map view around that neighborhood is kept in browser storage, as described below.
- Share images. The PNG created by “Save image” is drawn in your browser.
- Browser storage (localStorage). The site remembers the last layer you viewed, the map position and whether you have seen the short introduction, so the map opens the same way next time. This stays in your browser; you can clear it in your browser settings.

Analytics
We use Cloudflare Web Analytics to count page views. It does not use cookies and does not collect information that identifies you.
Requests to other services
- Base map. The background map tiles are loaded directly from the Geospatial Information Authority of Japan (GSI Tiles) for the part of the map you are viewing. Their server receives your IP address and the tile area.
- Hosting. The site is served by Cloudflare Pages. To deliver it, Cloudflare processes request logs such as IP address, time and browser type.
- Outside links. “Find places to stay nearby on a map” opens Google Maps. What happens there is covered by Google's privacy policy.
