In one line: this game collects almost nothing about you. Apart from the nickname and score you choose to submit to the leaderboard, everything stays in your own browser.
The following is kept in your browser's local storage. We cannot see it and it is never sent to any server:
Clearing your browser's site data removes all of it permanently. It does not sync to another browser or another device.
Only after you enter a nickname on the result screen and confirm is that run submitted to the global leaderboard: nickname, score, level reached, highest combo, whether you cleared the game, and the submission time.
A randomly generated anonymous player ID is sent with it, used to attribute the score and for basic validation. It is not an account and does not sync across devices.
No confirmation, no upload. Practice runs and Daily Challenge runs are never uploaded.
Please note: nicknames and scores are public. Anyone visiting the leaderboard can see them, and they are kept long-term. We do not ask for, and do not recommend, your real name or any contact details. We collect no email address, phone number, date of birth, location or any identifying information.
The site uses Cloudflare Web Analytics to count how many people open which page. It sets no cookies, puts no identifier on your browser and does not track you across sites, so we cannot tell that two visits came from the same person. All we see are aggregate numbers: page addresses, view counts, referring sites and a rough country / device type.
The site shows English by default. You can switch language at any time with the toggle, and your choice is remembered locally. That decision happens entirely inside your browser — nothing is sent out, and we never look up your IP location.
| Service | Purpose | What it can see |
|---|---|---|
| GitHub Pages | Website hosting | As with visiting any website, server logs contain routine access information including IP addresses |
| Supabase | Leaderboard storage | Only the items listed in section 2 |
| Cloudflare Web Analytics | Counting page views | Page address, referring site, and a rough country and device type inferred from the IP; no cookies, no records that identify a person |
No other third party has access to your data.
This is a casual game and we know children play it.
To remove your entry from the leaderboard, email us with the nickname and roughly when it was submitted, and we will take care of it.
Locally stored data needs no request — clearing your browser's site data removes it.

If what we collect changes (for example if advertising is ever switched on, or we change analytics provider), we will update this page and the date at the top.
