Cubion Privacy Policy & User Agreement

1. General provisions

Cubion ("Cubion," "we," "us," or "our team") respects the privacy rights of all users and strives for transparent communication. This privacy policy and user agreement (the "Policy") describes how we collect, use, store and share information when you access our website and the Cubion launcher (together, the "Services").

By using the Services, you confirm that you have read and accept the terms of this Policy. If you do not agree, please do not use our Services. This Policy applies only to Cubion and does not govern third-party websites, services or applications (such as Microsoft, Mojang, CurseForge, Modrinth, Discord, etc.), which have their own terms and privacy practices.

Cubion is designed to launch only the official, licensed version of Minecraft. We do not support or encourage the use of pirated or unlicensed copies of the game. Users are expected to adhere to the licence agreements of Mojang/Microsoft and other rights holders.

The Cubion team firmly opposes fraud, abuse and unauthorized use of the launcher or game. We take reasonable measures to detect and prevent fraudulent activity and to protect our users and infrastructure.

2. Information we collect
