Dot Siege has no accounts of its own, no sign-in and no user profiles, and it never asks you for your name, your email address or any other personal detail. What follows is everything it does with data. Where the answer depends on where you are playing, this page says so rather than picking one place and speaking for all of them.
The game is published in several places and two kinds of them behave differently. On this site, on itch.io and in the iOS app there is no advertising and nothing from a third party that watches you. On a game portal - CrazyGames, Poki, Y8, Yandex Games - the game loads that portal's own SDK, which is what shows the advertising, and that portal's privacy policy covers it. Their policy applies alongside this one rather than instead of it: this is the only document that describes the match service.
Your settings, your progress and unlocked cosmetic items, the offline match you are currently playing, and your daily challenge record. All of it lives in your own browser or app storage, none of it is sent anywhere, and clearing your browser data or deleting the app removes it.
An online match - by room code or through the public queue - opens a connection to a small match service we run, which relays the game and referees it. The service receives the moves, the room code, the settings the match is played under, and something that identifies your seat in the room.
On this site, on itch.io, in the app and on Poki, Y8 and Yandex, that seat identifier is a random one the game makes up on your device the first time you play online: a browser rather than a person, tied to no account, and gone when you clear your storage. On CrazyGames, if you are signed in to your CrazyGames account, the game uses the identifier and public display name that portal supplies instead, and that name is what your opponent sees across the board; if you are not signed in, it is the random identifier again. We neither issue those account identifiers nor use them anywhere outside the match.
While the match is being played the service holds it, moves included, because refereeing means checking every move against the position rather than trusting either player's browser. It deletes what it held once the match has ended and both players have left the room. Your connection reaches the service through Cloudflare, which like any host sees the network address it came from; our own code neither reads nor stores it. We build no profile from any of this, and no email address or other contact detail ever reaches us, because the game never has one to give.
We run no analytics service and nothing here measures how you play in order to profile or advertise to you. On this site, on itch.io and in the iOS app, nothing about your play leaves your device except an online match, which sends what the section above describes. The match service keeps a short operational log of rooms opening, pairing and ending so we can tell whether it is working; no player is named or identifiable in it.
On a game portal, more does. The portal's SDK may show advertising between completed matches. The game reports when play starts and stops to those portals whose SDKs ask for it - in every mode, not only online, because that is how a portal knows whether you are on a board or in a menu. And opening an online room hands the room code to the portal you are playing on: on CrazyGames, along with whether the room is joinable, so it can offer its own invite button; on Poki, so it can build the invite link, because only that portal knows the address of the page you are on. A room code is five characters that name a game, and it says nothing about you. All of this is the portal's to handle under its own privacy policy.
The game asks nothing about you and is built so that it does not need to know who is playing; everything except an online match works with no connection at all. It has no chat and no way to reach another player beyond the moves on the board. The one piece of text that ever travels between players is a CrazyGames display name, which that portal already shows publicly. Where a CrazyGames account supplies an identifier and a display name, that account and everything behind it belongs to CrazyGames rather than to us.
This policy is linked from inside the game, in the Settings dialog beside the copyright notice, wherever the game is played. It is the same document you are reading now, and the date at the top is how you can tell whether it has changed since you last looked.
