This page explains what this site (ikasumi works) keeps, and what it doesn’t.

Maze Rush accounts

You can play practice without signing up. Ranked play is only for players who sign up with a name and a password. When you sign up, the site’s server (on Cloudflare) keeps:

Your name (shown on the ranking and in the news ticker at the top)
A hashed form of your password (the password itself is never stored)
A hashed form of your recovery code (the code itself is never stored)
Your rating (including an internal value, not shown on screen, that sets the size of your first maze), how many ranked runs you’ve played, and your best ranking position
Your streak (how many days in a row you’ve played ranked)
For a ranked run in progress: the maze seed and start time (deleted when the run ends)
How many times in a row a wrong password or recovery code was entered, and when the last one was (to lock logins and recovery for 15 minutes after 10 tries)
When you signed up, and the times needed to enforce the rules (such as one ranked start every 10 seconds): your last start, when you reached your current rating, and the last day you played

When a ranked run ends, your moves in the maze (up, down, left, right, and when you used items) are sent to the server. The server replays them step by step to recount your clears. The moves themselves are not stored. The ranking and the news ticker only show your name, rating and position.

Ranked runs are head-to-head matches. During a match, your opponent can see your registered name, rating, clears, time left, and your maze board and ball movement (sent only to show on their screen, never stored). Who you played, each side’s clears, and the result are kept for 2 days so the server can decide the result and update ratings, then deleted.

Maze Rush Brain Training progress

You can play Brain Training without signing up. If you have signed up, we also keep your Brain Training progress (unlocked stages, stars and steps) on our server (Cloudflare), so it is the same on PC and phone. We keep only your best star count for each stage, the number of steps on that try, and when it improved, plus the time of your last save so that saves can’t be sent too often. Your moves inside the maze are not sent. If you have not signed up, your progress stays only in your browser. When you log in, your browser’s progress and your account’s progress are combined, keeping the better result for each stage.

Records used to improve the game

For each ranked run, we keep the date, the starting level, the number of clears, how long it lasted, and how many items were used. These records don’t say who played, and they’re deleted after 30 days. We also count, per day, how many people played, how many runs were started, and how many people signed up (numbers only).

ikasumi Prompt Checkpoint

The prompts you check are examined only inside your browser. They are not sent to this site’s server and are not saved, not even in your browser’s storage.

What we don’t keep

Email address, real name, address, or phone number
IP addresses (this site doesn’t store them)

To stop the same person from sending too many requests in a short time, a Cloudflare feature may count requests per IP address.

Login cookie

While you’re logged in, your browser keeps a login cookie (a random string used only by this site). It lasts 30 days and is extended when you play. Logging out removes it from both your browser and the server. The server only stores a hashed form of it.

If you forget your password

We don’t ask for your email, so we can’t reset passwords by email. Instead, the recovery code shown once when you sign up lets you set a new password. If you lose the recovery code too, the account can’t be recovered.

Deleting your account

Log in to Maze Rush, open Settings, choose “Delete account” and enter your password. Your name, password, rating, ranking record, your name in the news ticker, your login cookie, and your Brain Training progress are all deleted. The anonymous run records and daily counts described above stay, because they can’t be linked to you.

Stored only in your browser

Your sound, look, effects, language and D-pad settings, your practice best, your Brain Training progress (unlocked stages, stars and steps), and which new-gimmick tips you have seen are kept only in your browser’s storage (localStorage). Clearing your browser’s site data removes them.
