Early access. SLIME DUEL is unfinished and still being built. Expect bugs, downtime, balance changes and resets of progress, items and gems.

This explains what SLIME DUEL collects when you play at slimeduel.com, why, and what you can do about it. We collect as little as we can: there are no ads, no ad trackers and no cookies.

What we store about your account

• An account id, created at random the first time you play, and a session token your browser keeps (we store only a one-way hash of it).
• A username and password, if you add a login. The password is stored only as a salted, one-way scrypt hash; nobody can read it back.
• Your progress: level, XP, gems, items, crates, match stats, rating, challenges and Battle Pass tiers, plus a log of every change to them (so we can fix mistakes and undo cheating).
• Your choices: display name, look, loadout, settings and the flag you pick.
• Your time zone offset, so daily rewards reset at your midnight.
• A one-way hash of your IP address, used to limit sign-up and login attempts and to check that invite rewards come from different connections. We never store the address itself.

What other players see

Your display name, look, level, rating and flag are shown to other players in matches and on the leaderboard. In online rooms your game actions and lobby chat are sent to the other players in that room; the server passes them on and doesn't keep them.

Counting new players

When a new player starts, we add one to a daily count by country (from our host's country lookup) and by the website that linked to the game. These are just totals: they aren't connected to your account.

Support messages and reports

If you contact support or report a player, we keep your message, the email address you give (optional) and, if you leave the box ticked, game info such as the game version, stage and your browser. Messages are emailed to our support inbox so we can reply.

Who processes it

• Cloudflare hosts the game and its database, and keeps short-lived request logs for running it.
• AgentMail delivers support messages to our inbox.

We don't sell your data or share it with anyone else, unless the law requires it.

On your device

The game keeps your session token, a copy of your progress and your settings in your browser's local storage. Clearing site data signs the device out (a guest account without a login can't be recovered after that).

How long we keep it

Account data stays while your account exists. Support messages are kept for as long as they're useful for support and safety. Deleted accounts are removed from the live database right away.

Your choices

Email support@slimeduel.com from the address you'd like us to reply to, with your username (or your account id for a guest account), to get a copy of your data, correct it, or delete your account. We'll answer within 30 days.

Children

The game isn't aimed at children under 13. If you believe a child under 13 has given us personal information, such as an email in a support message, contact us and we'll delete it.

Changes

We'll update this page when what we collect changes; the date at the top shows the latest version.
