Color Vision Dot Game is a free game with no accounts. This page explains what happens to information when you visit colorblindtestonline.com.
Your game progress stays on your device
Your last 30 games are saved in your browser’s localStorage on this device. Each entry holds the date and time, whether it was a daily game, the game’s seed number, how many plates you matched, and which informal summary you got. These entries are not uploaded, and we cannot see them. They do not follow you to another phone or browser.
The game also saves your best score and results of challenges you played on this device. A challenge link contains only the score, the date or seed number of the plates, and a name if you chose to type one. It carries no health information.
The game never asks about your health, and its results are not a health record of any kind. The share text only goes anywhere if you copy it and send it yourself. If your browser blocks storage the game still runs, but your history will not be kept.
Analytics
This site uses Google Analytics to measure visits. It uses cookies or similar identifiers to count things like which pages are opened, roughly which region visitors come from, and what kind of device or browser they use. Google processes that information. We use it to understand how the site is used. Your browser settings can block or delete these cookies, and if a consent notice appears for you, your choice there applies.
Hosting
The site is hosted on Cloudflare. Like any web host, Cloudflare processes standard request data, such as your IP address, browser details and the page requested, so it can deliver the site and protect it from abuse.
Advertising
The site does not show ads today. Advertising partners may be added in future, and this page will be updated when that happens.
How to clear your data
Finish a game, then press Clear history under “Your history on this device” on the results screen, which also clears your best score and challenges. You can also open your browser’s settings, find the stored site data or cookies for colorblindtestonline.com, and delete them, which also removes analytics cookies set on this site.
Children
This site is not directed at children under 13. The game does not ask anyone for a name, age or email address. If you are a parent or guardian with a question about this page, use the contact below.
