Privacy

Last updated 2 August 2026.

What is stored, and where

Your scores, personal bests and daily streak are saved in your browser's local storage under a single key. That data stays on your device. It is not uploaded, not synced between your devices, and not visible to anyone else.

Clearing your browser's site data for this domain deletes all of it. Private or incognito windows discard it when you close them, and if your browser blocks local storage entirely the tests still work — you simply get no saved history, and the page says so.

What is not collected

There are no accounts, so there is no name, email address or password to collect. There are no tracking cookies and no third-party analytics scripts. The tests themselves send nothing to any server: once the page has loaded, everything runs locally in your browser.

Server logs

The site is served by Cloudflare, which processes standard request information such as IP address, user agent and requested URL in order to deliver the page and protect against abuse. That processing is Cloudflare's, described in their own privacy documentation, and it is not used here to build any profile of you.

Advertising

The site currently shows no advertising. If that changes, this page will be updated before any ad code goes live, and it will say plainly which network is used and what that means for cookies and consent.

Children

The site is not directed at children and collects nothing that could identify anyone of any age.
