Table Top Demolition Derby

Privacy Policy

Last updated 2026-11-03.

This game asks for almost nothing, and this page is short because there is almost nothing to say. If anything below stops being true, this page is wrong and should be fixed before it is trusted.

Playing on one device

Playing locally — one device, two players or against the computer — sends nothing anywhere, unless you have said yes to anonymous reports (see Anonymous reports below; the answer is No until you give it). Your settings (sound, camera, accessibility options), match history between two named players, and an in-progress match you can "Continue" are all stored only in your browser's own local storage, on your own device. Nothing is uploaded, and nothing is shared with us or anyone else. Clearing your browser's site data for this game erases it.

Playing online

Online play works by connecting your browser and your opponent's browser through a relay server so the two of you can play the same match. To do that, the server necessarily sees:

The server does not run the game and does not analyse matches. Online matches are not written to disk: a room and everything in it disappears once it has been empty a while. The exception is anonymous reports: when both players have said yes to them, the relay keeps an anonymous log of the match (no names, no account, no room code). The one exception: when both players are signed in to online accounts, the result (the mode, the map, the score, who won and when) is saved to both players' match history. The game does not match you with strangers: you only ever play someone who has your room's four-letter code.

Online accounts (optional)

Only if you create one under Account, the game makes an online account so you can keep your progress safe, sign in on another device and play friends online under your own name. Creating one yourself is for players aged 16 or older; a younger player's account is made by a parent (see Children below). You do not give a phone number or real name, and you do not sign in with Google, Apple or anyone else. An email address is optional: an adult account with a password can add a recovery email (see below). The server then stores, on our server in Germany:

If you use the online extras, the account also holds:

A backup code you make, or a sign-in code a parent makes for a child's device, works once, for 24 hours, and is stored only as a hash. Your IP address is used to limit how fast requests can be made and is not stored with the account. Nothing is shared with anyone, and nothing is used for advertising. Your account is never connected to anonymous reports (see below).

How long it is kept. Everything above stays until you delete your account, except where it says otherwise: shared clips and challenges after 90 days, extra tries at the lanes and the month after a week, game invites after ten minutes, an unconfirmed recovery email after seven days. That means your daily challenge scores (with the record of the match they were worked out from), your comments (a comment you delete, or a moderator removes, is marked removed and its text is no longer shown) and your match history are kept until you delete your account. The game no longer has ratings or a ranked mode: the ratings and match checks it once stored were deleted in November 2026.

You can download everything stored about your account (Download my data) and delete it (Delete account) at any time under Account; deleting removes it from the server immediately, together with any child accounts you made. You can also delete it from a web page, without opening the game, if you are signed in in that browser: Delete your account. Backups of the account database are kept for up to 30 days, on the server and in one off-site copy, and then deleted. Progress on your device stays. Accounts not used for 24 months are deleted automatically (the server checks every hour). Use means signing in or playing while signed in; a parent's account and its child accounts count as one family, so none of them is deleted while any of them is still in use.

Anonymous reports (only if you say yes)

After your first game it asks one question: Help make the game better? Both answers are the same size and the game plays exactly the same either way. If you say No, or never answer, nothing in this section happens: the game collects nothing and sends nothing. If you say Yes, the game sends anonymous reports to our own server in Germany, and you can turn that off at any time in Settings > Account > Send anonymous reports; turning it off stops it at once and throws away whatever was waiting to be sent. The question is never asked on a child account, and a child account never sends reports. Under 16? Ask a parent.

What is sent. Nothing in it is your name, your account, your IP address, a room code, anything you typed, or an id that stays the same from one visit to the next.

How it is kept apart from you. Each visit gets a new random number that exists only in the page's memory and is never saved on your device, so one visit cannot be connected to the next. Times are kept to the hour. The reports are stored in separate tables that have no account number, name, IP address or room code in them, and nothing links them to your account, your online match history or the daily leaderboard. Our server receives your IP address in order to answer the request, as any server does, and the game's code does not write it down. The game never sends reports from a test copy or from any web address other than the game's own.

How long. Individual reports and visits are deleted after 90 days, full match logs after 180 days, and the summary of a match (mode, table, score, length) after two years. Counts that contain nothing per person (for example how often a button was pressed per day) may be kept longer.

Because it is anonymous, it cannot be looked up. We cannot tell which reports are yours, so we cannot show you "your" reports or delete only yours. Switching it off stops any new ones, and the old ones disappear on the schedule above. The legal basis is your consent (Art. 6(1)(a) GDPR, and section 25 TDDDG for reading your device's details); you can withdraw it at any time with the switch. No third party receives any of it: there is no analytics service and no advertising.

Counts that need no consent. Separately from the above, the online relay server counts its own work, per hour and with nothing about any player: how many rooms were made, joined or expired, how often someone left or reconnected, and how many connections it had to refuse. This is the server counting itself, not you.

The mobile app downloads game files

The Android and iPhone/iPad app comes with a small core of the game and can download the rest (more car models, map scenery and music) from our server in Germany, the same files the web game loads. It asks you first, and you can remove them again in Settings under Account → Game files. To do that the app asks our server for the files and the server necessarily sees your IP address, which any server sees from any connection made to it, the same as visiting any website. It is not stored with any account and is not connected to any anonymous report. The app sends no name, account, device identifier or gameplay data with these requests, and the downloaded files are stored on your device only. Without a connection the app keeps working with what it already has.

No tracking, no ads

You never need to sign up or log in to play. The only lasting identifier is the optional online account above, which exists only if you create it. The game does not use advertising or any third-party tracking script or analytics service. Unless you have said yes to anonymous reports, nothing here reports back to us or anyone else about how you play. The game connects to our server only when you choose to play online, have chosen to save your progress online, or have said yes to anonymous reports, and, in the mobile app, to download game files.

Children

The game is intended for general audiences, including children playing with a parent, exactly as it started. Playing locally needs no account at all. Online play without an account only shows the name you type in — do not use your real name if you would rather not share it with a stranger. In a match, players can only send preset phrases and stickers, never their own text, and either player can mute the other. Nobody can be searched for by name, and the game has no matching with strangers at all: a child only plays someone who has the room's code.

Child accounts. Players under 16 cannot create an account themselves. A parent with their own account makes one from Account > Family, which is how they give consent, and then gives the child a one-time code to sign in on their device. A child account stores the same things as any account except a username and password, plus which parent manages it. Its name is picked at random from friendly word pairs (like "Turbo Badger"), never typed, because names can appear on leaderboards. A child's name is shown only to that child's family and friends, never on a public leaderboard. The parent decides whether the child can play online (not at all, only with friends and family, or with anyone who has the game's code), whether new friends need the parent's approval or are switched off, whether quick chat is on, and whether sharing a score or a clip from the child's phone first asks a grown-up (a question on the phone, never stored or sent) or is switched off. Children cannot write comments. The parent can see the child's friends and recent matches, sign the child out everywhere and delete the child's account at any time; deleting the parent's account deletes the child's too.

Turning 16. When a young person turns 16 their parent can hand the account over (the parent says so; no date of birth is stored). The young person then chooses their own username and password on their own device, the account becomes an ordinary account with no parent, and the family become friends. It is never switched to public leaderboards by this.

Changes to this policy

If what the game collects or sends ever changes, this page will change with it and the date at the top will be updated.
