Privacy Policy

This page explains what ChuniMaru stores, why it stores it, and how data related to your account and sync features is handled.

What ChuniMaru Collects

ChuniMaru may store your login email through Supabase Auth, your chosen username and preferences, imported CHUNITHM records, synced favorites, Todo data, and other account-related settings needed to operate the site.

Automatic Sync and Local Tools

If you use automatic sync or import tools, ChuniMaru may use local browser storage and local sync helpers to hold the information needed to refresh your data from CHUNITHM-NET. Some connection details may be kept on your device so future syncs can work without repeating setup each time.

How This Data Is Used

  • To log you in and keep your account available across sessions.
  • To display your records, ratings, favorites, and Todo information inside ChuniMaru.
  • To run optional sync features that you choose to use.
  • To keep the site functional, troubleshoot issues, and improve the user experience.

Third-Party Services

ChuniMaru relies on third-party services to function. This currently includes Supabase for authentication and data storage, and user-initiated communication with CHUNITHM-NET when sync features are used. ChuniMaru is an unofficial, non-commercial fan project and is not affiliated with or endorsed by SEGA.

Game Content Ownership

Game-related names, art, music, charts, trademarks, and other CHUNITHM materials shown or referenced by ChuniMaru are owned or copyrighted by SEGA or their respective owners. For official information, see the CHUNITHM site and the music list below.

Retention and Deletion

Account data is generally kept while your account remains active. If you want your account data removed, contact the site operator. Data stored locally on your device may also need to be cleared from your browser or local sync setup.

Your Choices

You may stop using sync features at any time, update your preferences from the account page, or request deletion of your stored account data. Because ChuniMaru is a small fan project, requests are handled manually.

Contact

For privacy questions or deletion requests, please contact the project operator through the project's listed contact channel.
