Terms of Service

Effective 2026-04-18 · Private Beta

Plain-language summary — You're joining a private beta. Don't leak builds. Don't reverse engineer. Don't use it to cheat. It might break, and we might remove your access. By installing, you agree to the terms below.

1. Acceptance

By downloading, installing, or using Blue Client (the "Client"), you agree to these Terms of Service. If you do not agree, do not install or use the Client.

2. Eligibility

  • You must own a valid Minecraft (Java Edition) account.
  • You must have received a beta invite or otherwise been granted access by us.
  • You must meet the age requirements for Minecraft in your country.

3. Private Beta nature

The Client is in private beta. This means:

  • Features may change, disappear, or break between builds.
  • Data (settings, HUD positions, config) may be reset at any time.
  • The Client is provided as-is, without guarantees of stability or fitness for any purpose.
  • Beta access may be revoked at our discretion, with or without cause.

4. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and run the Client on computers you control, solely for the purpose of participating in the private beta.

You do not acquire any ownership rights in the Client. All rights not explicitly granted are reserved.

5. Restrictions

You agree not to:

  • Redistribute beta builds. Do not upload, share, sell, or otherwise distribute the installer, binaries, or build files to anyone.
  • Reverse engineer. Do not disassemble, decompile, or attempt to extract the source code, protocols, or internal APIs of the Client, except where such restriction is prohibited by applicable law.
  • Modify the Client or create derivative works, injections, or plugins without explicit permission.
  • Use the Client to cheat on servers that prohibit client modifications, or to circumvent anti-cheat systems.
  • Bypass, interfere with, or attack our servers, authentication, or the servers of other operators.
  • Impersonate us or misrepresent the origin of the Client.
  • Sell beta access or trade it for anything of value.

6. Server rules are your responsibility

Each Minecraft server sets its own rules about third-party clients. Some servers prohibit all non-vanilla clients. You are solely responsible for understanding and following the rules of any server you connect to. We are not responsible for bans, mutes, or other actions taken by server operators.

7. Known issues and anti-cheat

The Client has known compatibility issues with some anti-cheat systems (currently: Grim AC on strict thresholds). These issues are bugs, not features. We are working on them. Use at your own risk on servers with strict anti-cheat policies.

8. Accounts and authentication

The Client uses Microsoft's official authentication. You must not share your Microsoft credentials with us, and we never ask for them. You are responsible for the security of your Minecraft account.

9. Intellectual property

The Client, its source code, assets, trademarks, and branding are owned by us or our licensors. "Minecraft" is a trademark of Mojang Studios. We are not affiliated with or endorsed by Mojang Studios or Microsoft.

10. Termination

We may suspend or terminate your access to the Client at any time, with or without notice, including (but not limited to) for violations of these Terms, leaks of beta builds, or malicious use.

On termination, you must stop using the Client and delete any copies in your possession.

11. Disclaimer of warranty

THE CLIENT IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE CLIENT WILL BE UNINTERRUPTED, BUG-FREE, OR COMPATIBLE WITH ANY PARTICULAR SERVER, PLATFORM, OR ANTI-CHEAT.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, ACCOUNTS, SERVER ACCESS, OR IN-GAME ITEMS, ARISING OUT OF OR RELATED TO YOUR USE OF THE CLIENT.

13. Indemnity

You agree to indemnify and hold us harmless from any claim arising out of your use of the Client, your violation of these Terms, or your violation of any third-party right (including server rules).

14. Changes to these Terms

We may update these Terms from time to time. Material changes will be announced in the Discord. Continued use of the Client after changes constitutes acceptance.
