Trust, security, and ethics
hmcl.computer explains HMCL with the same seriousness as a professional software program: integrity expectations, licensing transparency, and clear boundaries for acceptable use.
Legal usage policy in plain language
Use HMCL to launch and manage Minecraft in compliance with Mojang and Microsoft terms, local law, and the policies of any network you join. Do not use launcher capabilities to harass players, attack servers, distribute malware, or evade enforcement actions.
This website does not grant you any rights in Minecraft intellectual property. Trademarks belong to their respective owners.
Ethical usage statement
Respect multiplayer communities
Follow server rules, disclose client mods when asked, and avoid automation that degrades shared worlds or creates unfair advantages.
Protect younger players
Adults should supervise installs, downloads, and chat exposure. HMCL makes downloads easy, which increases the importance of curation and household rules.
No harassment, no harm
Tools that manage powerful software carry responsibility. If a feature could be misused to harm people or systems, refuse that misuse and report credible abuse to the appropriate platform or authority.
Open-source transparency
HMCL is GPLv3 software. The license is a public contract: it encourages sharing improvements, preserves user freedom, and anchors expectations that the community can inspect how the program is built. Transparency is not a guarantee of perfection, yet it is a meaningful security practice compared with opaque installers.
What transparency does and does not prove
Transparency proves that source is available under license terms. It does not remove the need to verify the exact binary you execute, especially when you download from a third-party mirror.
Malware clarification
hmcl.computer does not claim infallibility for any mirror on the public internet. Responsible security posture is layered: reputable channel, hash verification, limited blast radius on first run, and updated endpoint protection.
If an antivirus product quarantines HMCL, treat the event seriously, then triage methodically. Many legitimate launchers trigger heuristics. A quarantine alone is not proof of malice; a hash mismatch is strong evidence of tampering.
User responsibility disclaimer
You are responsible for backups, compatibility testing, and compliance. hmcl.computer content is provided for general information. No warranty is made about fitness for a particular purpose, uninterrupted operation, or compatibility with every future Minecraft release.
To the extent permitted by law, hmcl.computer disclaims liability for damages arising from use or inability to use HMCL, including data loss or downtime, except where such limitation is not legally enforceable.
