- The service. MU Insta is a free, non-commercial MU Online fan server, provided "as is", without guarantees of availability. It may be changed, reset or closed at any time.
- Your account. You are responsible for keeping your password secret and for everything done with your account. Use a password you do not use anywhere else.
- Conduct. You agree to follow the rules. The staff may suspend or delete accounts that break them.
- Data. We store your login, a secure hash of your password, your e-mail address and game data (characters, items). Your password is never stored in readable form. We do not sell or share your data. Server logs (IP address, time) are kept for security and abuse prevention. You can ask for your account to be deleted at any time.
- Cookies. We use one essential session cookie to keep you logged in and to protect forms. The language is chosen by the address (Portuguese under /br), not by a cookie.
- Advertising measurement (Meta Pixel). To measure our ads on Facebook and Instagram, the site loads the Meta Pixel. It tells Meta which pages were visited and when an account is created or Play is pressed, and Meta may set its own cookies (such as
_fbp) for this. We never send your password, e-mail or game data. You can opt out by blocking third-party cookies or trackers in your browser (for example with Safari's or Firefox's tracking protection or a content blocker), by turning off ad personalisation in your Facebook/Instagram ad settings, or at Meta's ad preferences help. The game itself works the same either way. - Intellectual property. MU Online is a trademark of Webzen Inc. This project is not affiliated with Webzen.
- Age. If you are under 13, ask a parent or guardian before creating an account.
