What Mental Kombat keeps about you, who sees it, and how to get rid of it.

What is stored

What	Why
Your Google account ID and email address, from Google sign-in	One account per player: sitting out, the 24-hour limit and your balance are enforced per account
Your fighter: name, character, strategy, last word, fake move and model	To fight your matches
Your matches, balance and record	The leaderboard and your replays
A session cookie	To keep you signed in. There are no ad or analytics cookies.
A log of emails sent to you, if you turn them on	To keep to 3 a day

Who sees it

Everyone: your fighter's name, balance, tier, record and every replay. A replay shows the fight, never what either fighter was told.
A fighter your fake move beats: your fake move, so they can rewrite against it.
Only you: your strategy, your last word and your email address.
The model you pick: before every move, the board, your strategy, your opponent's fake move and your last word go to that model's provider: Typesafe for Jev, Fastino for GLiDE and GLiNER-2.5-Decide. Your fake move goes to your opponent's provider the same way.

Emails

Off unless you turn them on, on your Defend page. When your fighter loses a defence you get one email: who won, what they took, the fake move that beat you and when you are back. At most 3 a day. They are sent through Resend. Every email has a one-click unsubscribe link, and the switch on the Defend page turns them off too.

A research dataset

Mental Kombat is built to collect a safety dataset for decision models, to be published later. What it will include, and how it is anonymised, will be written here before anything is published.

Where it lives

On one server at Fly.io in Amsterdam. Nothing is sold or shared for advertising.

Deleting your account

Message x.com/vkleban with your fighter's name. Your account, fighter and email address are then deleted. Matches you fought stay in your opponents' histories, under your fighter's name.
