​
1. Account Registration and Naming Standards

  1. Email Authentication: You agree to provide a real and valid email address. This email will be used for account activation, security verification, and password retrieval.
  2. Account Security: Your account is for your personal use only. Any behavior generated through your account will be deemed as your own behavior.
  3. Naming and Profile Restrictions:
    • Prohibited Content: It is strictly forbidden to register usernames (IDs), nicknames, or personal signatures containing the following content:
      • Information that violates local laws and regulations;
      • Content involving political sensitivity, religious extremism, racial discrimination, or gender discrimination;
      • Insulting, abusive, or offensive vocabulary;
      • Names impersonating administrators or other famous figures.

​
2. Avatar Service Statement

  1. This game integrates the Cravatar third-party avatar service.
  2. Data Processing: In order to display your avatar, your registered email address will be sent to the Cravatar server for matching after being encrypted and hashed (Hash).
  3. Content Compliance: Although the avatar is hosted by a third party, the avatar content displayed in this game must comply with the principles in the above “Naming Restrictions”. Using violating avatars (such as involving politics, pornography, violence) will result in the account being banned.

​
3. Custom Content Guidelines

  1. User Spontaneity: The custom interfaces (UI), skins (Skins), hit sounds (Hitsounds), etc. imported by you during the use of this game are all your personal local behaviors.
  2. Compliance Requirements: Although these contents are only stored on your local device, if you disseminate custom skin images containing political sensitivity, pornography, or illegal content to the game community (such as leaderboard screenshots, forums, etc.) through screenshots, videos, etc., the platform has the right to punish your account.

​
4. Leaderboards and Fair Competition

  1. Strictly Prohibit Cheating: It is strictly forbidden to use cheats, macros, speed hacks, modify local client files, or forge network data packets to upload fake scores.
  2. Penalties: Cheaters will be permanently removed from the leaderboard and their accounts will be banned.

​
5. Data Upload Authorization

  1. You agree to authorize the platform to publicly display your game replay data (Replay Data) and score information on the leaderboard.
  2. Note: The uploaded data only contains key timestamps and statistical data, and does not contain any audio files, chart background images, or skin materials.

​
Part 2: Disclaimer

Important Note: This software is merely a “Player/Simulator” and a “Score Recording Tool”.

​
1. Definition of Software Nature

Cachi is a non-commercial open-source/community-driven rhythm game simulator. This software aims to parse and run data files in specific formats.
  • No Content Provision: This platform does not provide, store, or distribute any copyrighted music files (Audio), chart files (Beatmaps/Charts), or background images.
  • Tool Attribute: This software only provides game engine (Engine) functions, and all content loading is completed by user operations.

​
2. About Game Resources

  1. Local Read Mode: All content played by users in the game is read entirely from the local storage of the user’s device.
  2. User Responsibility:
    • Users must ensure that the game resources imported or stored in their devices have legal sources.
    • If a user loads or plays unauthorized copyrighted content locally, all relevant legal responsibilities shall be borne by the user.
    • This platform cannot control nor review the content of files loaded by users locally, so it does not assume copyright responsibility for any audio or images loaded by users.

​
3. About Custom Skins & Modifications

  1. User Spontaneous Behavior: This game allows users to customize interface elements (UI), textures, and sound effects (i.e., “Skin” function). All such modifications are users’ spontaneous behaviors and have nothing to do with the software developers and operation team.
  2. Copyright and Responsibility:
    • The developers do not provide any official skin resource downloads.
    • If the custom materials (images, audio) imported by the user involve copyright disputes or contain politically sensitive/illegal information, the relevant responsibilities shall be borne entirely by the user.
    • The development team does not assume responsibility for repairing game crashes, data corruption, or visual anomalies caused by users modifying local files.

​
4. Platform Rights and Community Purification Statement

Although this platform does not control users’ local files, in order to maintain the community environment, we have complete management rights over the account system (Web side and leaderboards):
  1. Zero Tolerance for Politics/Violations: We are committed to maintaining a non-political and harmonious game environment. For users who use usernames (IDs), avatars, or public signatures involving political sensitivity, violations of laws and regulations, or hate speech, this platform has the right to not only delete their leaderboard data, freeze or cancel their accounts, but also assume no liability for compensation.
  2. Data Cleanup: For zombie accounts that have not logged in for a long time or registration behaviors determined to be malicious by the system, the platform reserves the right to clean up data.

​
5. Third-Party Compatibility Statement

This game provides parsing support for file formats such as .osu (osu!) and .mcz (Malody), aiming to facilitate users to migrate personal data and gaming experience.
  • This game has no official cooperation, authorization, or affiliation with osu!, Malody, or their developers.
  • All relevant trademarks and file format standards belong to their original holders.

​
6. Disclaimer Clause

This game is maintained by community enthusiasts and is provided “As-Is”. We do not guarantee the permanence and uninterruptedness of services (such as leaderboard servers, account login). The development team does not assume liability for compensation for data loss or inability to run caused by server maintenance, cyber attacks, force majeure, and users’ own local environment configuration.
