Privacy and terms

Last updated 30 September 2026

Survive is a free browser game. It has no accounts, no ads, no cookies, and no third-party analytics or trackers. This page explains what the game keeps, what it sends, how to remove your data, and the rules of the global leaderboard.

Survive is made and run by its developer, who is responsible for the data described here. You can reach them at .

In your browser

The game keeps its data in your browser's local storage, not in cookies:

• your settings (volumes, graphics, screen shake, reduced motion)
• your local top 10 scores
• once a run of yours goes to the global leaderboard, a random player id

Clearing this site's data in your browser deletes all of it. Your leaderboard entry stays; your next run to make the board starts a new one.

The global leaderboard

The leaderboard is the global top 100. When each run starts, the game loads the board (and your own entry, if you have one) so that it can tell, when the run ends, whether it made the board. A run that makes it (beating the last entry, and your own) goes to the board: the game asks for a name for it, and if you leave that blank it goes up as SUBJECT and a number. Other runs, and practice runs, aren't sent. A submission contains:

• the name, which anyone can see on the board
• the random player id, which is never shown: it's how the game finds your entry
• a recording of your run's inputs (which way you moved, and when you jumped or dashed), which the server replays to check the score
• the score the run reached

The board shows each player's best run: the name, points, levels cleared, and when it was set. The server keeps your best run with its recording, and a short record of every accepted run (its score, time, length, and a fingerprint of its recording) so that the same run can't be submitted twice.

Pick a nickname: don't use your real name.

Your name. Each run that makes the board gets the name you enter then; names can't be changed afterwards in the game. To have your entry renamed or removed, ask us (see Your rights). Removing it deletes the name and your best run with its recording, and unlinks your other runs from you: only their scores and fingerprints remain, so they can't be submitted again.

Sharing your score

SHARE SCORE on game over draws a score card in your browser: your points, levels cleared, what ended the run, your global rank if the run holds one, and a still of the test chamber. Nothing leaves your device until you pick where it goes:

• SHARE… hands the card, a short message, and a link to the game to your device's share menu
• POST ON X, POST ON BLUESKY, and SHARE ON FACEBOOK open that site in a new tab with the message and link filled in (Facebook takes only the link). You post it yourself, and that site's own privacy policy covers what happens there
• COPY TEXT puts the message and link on your clipboard, and SAVE IMAGE downloads the card

The game loads no scripts, buttons, or trackers from these sites, and doesn't tell anyone what you shared.

Anonymous usage statistics

To see how the game is played and where it's too hard, it sends a few anonymous facts:

• when the page loads: your browser family (Chrome, Edge, Firefox, Safari, or other), whether your screen is touch-first, and whether WebGL works
• when a run ends: the level it ended on, how long it lasted, what ended it, and whether a gamepad was used
• when the game lowers its graphics quality because it's running slowly

None of these carries an id, a name, or a cookie. The server only adds them to totals for each day and doesn't keep the individual events. If your browser sends Do Not Track or Global Privacy Control, the game sends no usage statistics at all.

Error reports

When the game hits an unexpected error, it sends the error message and stack trace (with this site's address removed), the game's version, and your browser family. These carry nothing about you, so they're sent even when Do Not Track or Global Privacy Control is on. Each distinct error is kept, with a count, until 90 days after it was last seen.

IP addresses and hosting

Like any website, the servers that deliver the game see your IP address with each request. The game's own code uses it only in memory, to limit how often one address can call the leaderboard, and never stores it. The game is hosted on Vercel, and the leaderboard's database on a managed MongoDB service; both act as our service providers. Vercel keeps request logs, which include IP addresses, for a limited time under its own privacy policy. These providers may process data in the United States.

How long data is kept

• Leaderboard entries: until we remove yours at your request (see Your rights) or under the rules below.
• Daily usage totals: indefinitely. They're anonymous.
• Error reports: 90 days after the error was last seen.
• Data in your browser: until you clear it.

Why we use it

Under the GDPR and similar laws, we use leaderboard data to run the leaderboard that comes with the game (to provide that service), and usage statistics and error reports because of our legitimate interest in keeping the game working and fair. We don't sell or share personal information, use it for advertising, or make automated decisions about you with it.

Your rights

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your data, to object to how it's used, and to complain to your data protection authority. To have your leaderboard entry renamed or deleted, or for anything else, email with the name on your entry.

Children

Survive isn't directed at children under 13, and we don't knowingly collect personal information from them. The leaderboard only asks for a nickname. If you believe a child has put personal information on it, tell us and we'll remove it.

Leaderboard rules

Runs that make the global leaderboard go up by themselves, and by playing you agree that:

• your name won't be offensive, won't impersonate anyone, and won't contain anyone's personal information, including your own
• you won't submit runs made with modified game code, automated input, or other cheats
• we may rename or remove any entry or run that breaks these rules, or that we reasonably believe does, without notice
• we may reset the board if changes to the game make old scores incomparable

No warranty

Survive is provided free and as is, without warranties of any kind. We may change, pause, or stop the game or the leaderboard at any time. To the extent the law allows, we aren't liable for any loss that comes from using it.

Credits and licenses

All of Survive's art and sound are generated by its own code. It's built with three.js (MIT License, © three.js authors). The license texts of the third-party code the game ships with are in third-party-licenses.txt.

Changes

When this page changes, so does the date at the top. If the game starts collecting anything new, this page will say so before it does.
