GUT CHECK has no accounts, no tracking, and no cookies. Your scores, streaks and history stay on your device. The one thing that is sent is an anonymous daily score, so the game can tell you how you compare. Clause 06 lists exactly what that includes.
There is no sign-up, no login, and no email required to play. You just open the page and go.
Your daily result, current streak, best score, games played, and whether you've already played today are saved only in your browser's localStorage, on your device. Your preferences and any in-progress GUT CIRCUIT (pass-and-play board game) are saved the same way, locally.
We never transmit that local game state on our own. Two things can carry it off your device, and you have to choose both. The first is the optional multiplayer features (clause 06): when you use them, your chosen display name, your scores, and (for a room) the room name and the instruments picked for each round are sent to our database so leaderboards, duels, and rooms work. The second is the share button on a finished GUT CIRCUIT game, which hands a plain-text scoreboard — the player names typed at setup, their coins, and a link to this site — to your device's own share sheet or clipboard. Where that text goes next is up to the app you send it to; it never reaches us. The daily game itself needs no server, and your local stats stay on your device.
Each day's five challenges are computed on your device from the date (a deterministic seed), so everyone gets the same puzzle without any server call. Practice and the GUT CIRCUIT board game also run entirely on your device, with no server call.
We don't use tracking cookies, advertising networks, third-party trackers, or browser fingerprinting. (localStorage is used only for your own game state, as above, not for tracking.)
We may use a privacy-friendly, cookieless analytics tool (e.g. Vercel Web Analytics) to count aggregate page views. It does not set cookies, does not track you across other sites, and does not collect personal data.
None of this uses an email, account, password, or cookie. Identity is an anonymous random id generated on your device, plus a display name you choose.
The daily percentile is automatic. To tell you how your score compares ("you beat 73% of today's players"), the game sends your anonymous id, the day number, your total and your five round scores to our server when you finish a daily run. This happens on every daily run, without a separate prompt, and it is what makes the comparison possible at all. We add the total to an anonymous daily distribution and record the id so each player is counted once. If the server cannot be reached, the game plays exactly the same and simply shows no percentile.
When you create or join a duel or a room, we store in our database: your display name, your total and per-round scores, the anonymous id that ties those scores to you (and marks the creator of a room as its host), the room name the host chooses, and the set of instruments picked for each round. Other people in the same duel or room can see the display names and scores on the shared leaderboard. A room is a persistent playlist: it stays available so friends can keep playing, and the host can add rounds over time.
This data lives in a hosted database (Upstash Redis, in the EU / Frankfurt region) used solely for rankings, duels, and rooms. On each request your IP address, and for gameplay requests your anonymous id, are used transiently to rate-limit abuse: each is held in a counter that expires after one minute and is not stored beyond that. Ranking, duel, and room data auto-expires about 90 days after it is created (playing again does not extend that). The id is random and anonymous, so a result cannot be tied to a real person unless you put identifying information into your display name or room name. If you never use a duel or a room, none of that happens and no display name or room name ever leaves your device. The daily percentile submission above still does, on every daily run.
GUT CIRCUIT also has an online mode, for playing the board game live with friends on their own phones instead of passing one phone around. When you play it, the display name you enter and your game moves (rolls, choices, scores and the time each was made) are stored on our server, so every player's phone can replay the same moves and show the same board. This uses the same anonymous id as the percentile, duels and rooms above (clause 06), and the game itself is identified by a random code, the same way a duel or a room is. An online game and its moves are automatically deleted about 24 hours after the game is created. Pass-and-play GUT CIRCUIT (one phone, passed around) is unaffected and stays entirely on your device, as described in clause 02.
The site is served by a hosting provider (Vercel). The optional multiplayer features run on serverless functions plus a hosted database (Upstash), as described in clause 06. Like any website, these may transiently process standard request data (such as IP address and browser type) to serve requests and protect the service against abuse. We don't combine this into profiles of you.
Inside the game there is an "erase my data" control (open view your history, then erase my data). It removes everything GUT CHECK keeps on your device in one step, without hunting through browser settings, and it works the same way in the app.
Clearing your browser's site data does the same thing: it erases your local stats, resets the daily lock, and generates a fresh anonymous multiplayer id. This disconnects you from any past multiplayer entries, and because the host of a room is identified by that id, you lose host control of any room you created (its existing rounds stay available to the other players). Any ranking, duel, or room data you already submitted is anonymous and auto-expires within about 90 days of inactivity; to request earlier removal, contact us (clause 12).
The game is suitable for a general audience and collects no personal information from anyone.
If this policy changes, we'll update the date above.
