TERMS & DISCLAIMER

A free, unofficial companion.

Prefecture Mate is a free, non-commercial, personal Japan travel companion for tracking visits to all 47 prefectures. It is a hobby project provided at no charge. The app is not sold, and it has no paid features.

Independence and trademarks

Prefecture Mate is independent and unofficial. It is not affiliated with, endorsed by, sponsored by, or operated by SEGA, CHUNITHM, or any related rights holders. Names, characters, logos, and other marks belong to their respective owners. They are used only to identify optional import sources or to describe them factually. This project does not claim official status.

Your account

You are responsible for keeping your Prefecture Mate credentials secure and for the accuracy of records you enter by hand. Deleting a Prefecture Mate account removes this app's data. It does not close, change, or affect any CHUNITHM-NET account.

External services

CHUNITHM-NET is an optional, unofficial import source for personal progress tracking. It is incidental to the product. The core of Prefecture Mate is the travel map and prefecture tracker, which remain fully usable without any game import. Import availability and page formats can change or stop without notice. You are responsible for your own third-party credentials and for not violating those services' terms of use.

No official data and no warranty

Prefecture Mate is unofficial. Imported or displayed data may be incomplete, outdated, or wrong. The service is provided as is, without warranties of any kind. Use it at your own risk.

Acceptable use

Do not present Prefecture Mate as an official SEGA or CHUNITHM product. Do not use it to access another person's account, disrupt or abuse external services, or submit credentials you are not authorized to use.
