Privacy

If you never sign in

We store nothing about you. No account, no cookie, no profile. Every values page, the tier list and the WFL calculator work entirely without signing in, and always will.

If you sign in with Discord

Signing in is only needed to post on the trade board. We ask Discord for one permission — identify — which is the narrowest scope there is. We do not ask for your email, your server list, your messages, or permission to act on your behalf.

From that we store:

• your Discord user ID
• your Discord username and avatar, so other traders can see who posted
• your account's creation date, used only to block brand-new throwaway accounts
• the trades you post, the offers you make and any reports you file

That's the whole list. We never see your Discord password, and we cannot read your messages or post as you.

Cookies

Two, both strictly necessary, neither used for tracking:

• A session cookie that keeps you signed in. It's HttpOnly, so scripts can't read it, and what we keep on our side is a one-way hash of it, not the value itself.
• A small "you're signed in" flag that carries no secret and grants no access. It exists so the site can skip a pointless server round-trip for the vast majority of visitors, who are signed out.

There are no advertising, analytics or third-party cookies.

What's public

A trade you post is public: your username, avatar, the items on each side and any note you add. That's the point of a trade board. Notes are filtered for links, invites and contact details before they're shown, because a public board is not a safe place to hand out those.

Individual listing pages are marked as not-for-indexing and are excluded in robots.txt, including for AI crawlers, so your posts aren't meant to end up in search results or training data.

How long we keep it

• Listings expire on their own after 7 days.
• Sign-in sessions expire after 30 days.
• Your account record stays until you delete it.

Deleting your data

Sign in and use Delete my account on your offers page. It removes your account, your listings, your offers and your session immediately, and takes any of your posts down from our Discord channel. It cannot be undone, and we don't keep a hidden copy.

If you can't sign in for any reason, ask in our Discord and we'll do it for you.

Where the values come from

Our MM2 values are calculated from public trade posts, and what we publish from them is a statistic — how often a given shape of trade is offered — never anyone's username, message text or user ID. See how values are calculated.

Young users

A lot of MM2 players are children. That shaped real decisions here: the narrowest possible Discord permission, no ads, no tracking, no data sales, filtering of contact details out of public notes, and self-service deletion. If you're a parent and want your child's data removed, ask in our Discord and we'll remove it, no questions asked.

Not affiliated with Roblox

MM2 Index is an independent fan project. It isn't run by, endorsed by or affiliated with Roblox Corporation or the MM2 developers. Signing in with Discord tells Discord you used this site; their own privacy policy covers that.
