Privacy Policy

Who we are

MU Nostalrius is a fan-run MU Online private server. It is not affiliated with or endorsed by Webzen Inc. For any privacy question or request, write to support@munostalrius.com.

Data we collect

• Account: your email address, account login name and password. Passwords are stored only as an Argon2 hash — we never see or keep the password itself.
• Game data: your characters, items, rankings, guild membership and online status.
• Purchases: the order, amount, currency, payment provider and status. Card and wallet details are entered on the provider's own page and never reach us.
• Votes: which toplist you voted on, when, and the IP address of the vote.
• Technical data: your IP address and browser details in server logs, used to run and protect the service.
• Support: the messages you send us by email or on Discord.

Why we use it

• To create and run your account and deliver what you buy — this is needed to provide the service you signed up for.
• To keep the game secure and fair: preventing fraud, cheating and account abuse (our legitimate interest).
• To send account emails: confirmation, password reset and important service notices. We do not send marketing emails.
• To measure how the website is used — only if you accept analytics cookies (your consent).

We do not sell your personal data and do not use it for advertising.

Who we share it with

Only with the services we need to run MU Nostalrius:

• Payment providers — PayPal, Pal24, Enot, AnyPay and NOWPayments — receive what they need to process a payment you start with them.
• Resend delivers our account emails, so it receives your email address.
• Google reCAPTCHA protects the login, registration and password forms against bots; Google receives technical data about your browser.
• Google Analytics, only if you accept analytics cookies.
• Vote toplists: your vote link contains your account login so the toplist can credit you, and for some toplists we send your IP address to confirm the vote came from you.
• Our hosting providers, which store the data on our behalf.

Some of these services process data outside your country. Each handles it under its own privacy policy.

Cookies

• Session cookie — keeps you logged in. Required.
• Realm cookie — remembers which game realm you selected. Required.
• Language — remembers the language you chose. Required.
• Analytics cookies (Google Analytics) — set only if you accept them in the cookie banner.
• Google reCAPTCHA may set its own cookies on pages with protected forms.

You can change your analytics choice at any time with the "Cookie settings" button below.

How long we keep it

Account and game data are kept while your account exists. Purchase records are kept as long as accounting and tax law require, even after an account is deleted. Vote records and logs are kept only as long as needed to prevent abuse.

Your rights

You can ask to access, correct, export or delete your data, object to how we use it, or withdraw your consent. Write to support@munostalrius.com from the email address of your account. If you live in the EU or the UK, you can also complain to your data protection authority.

Deleting your account

You can ask us to delete your account and its data at any time.

Game clients

The Windows and Android clients connect to our game servers with the same account as the website. They send what is needed to play — your login, your characters and your actions in the game — and your IP address, as every online game does.

Children

MU Nostalrius is not intended for children under 16. We do not knowingly collect data from children; if you believe a child has registered, contact us and we will delete the account.

Changes to this policy

If we change this policy, we update the date at the top. Significant changes are also announced on the website or on Discord.
