Privacy policy
What we never receive
This site does not receive your name, address, phone number, email address, date of birth, or location. When you sign in with LINE or Google we do not receive your email address, your profile picture, or the provider's account number. We ask only for openid profile.
What we store when you sign in
Signing in is optional. Without it you can still finish every game and use every setting and check in anywhere — your score simply stays off the ranking, and your settings and check-in records stay on the device.
- Display name
- As given by the provider. It appears on the ranking
- Token
- A string that ties your records together. It is a one-way calculation over the provider's account number and cannot be turned back
- Provider
- LINE or Google
- Scores
- Game, score, distance, and when it was set
- Settings
- Saved places, your area, your ferry route, and what the top page shows
- Check-in records
- Which list (cafes or shrines), the id of each place you marked as visited and when, the ids you saved as "want to go", and when the copy was last written. Your location is never sent — it is used only inside the browser, to sort the list by distance
The store has no other columns.
What we store about operators
We keep a list of the people who may correct game records. It holds only theirtoken, when they were added, and who added them. An invitation used to add someone is stored as a value we can check against, never the phrase itself, and it expires after 15 minutes. This is an operational list; nothing here is about visitors.

Deleting your data
Signing out clears the cookie, but your scores, settings and check-in records remain. Clearing site data removes what is held on the device. Check-in records can also be cleared from the "Clear every record" button on the check-in page.
To have your stored scores and settings deleted, please write to us through the contact form. Because the token cannot be turned back, we can only identify your records if you write to us while signed in with the same provider.
Changes
When what we store changes, this page is updated first.
