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 — your score simply stays off the ranking and your settings stay on the device.

- 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
The store has no other columns.

Deleting your data
Signing out clears the cookie, but your scores and settings remain. Clearing site data removes what is held on the device.
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.

When what we store changes, this page is updated first.
