Privacy policy

Last updated: 15 November 2026

Krillion Unlimited has no accounts and no sign-up. We keep as little as the game needs to work and to count how common each answer is. This page lists all of it.

Kept in your browser

Your daily results and streak, your last 100 endless and themed sets, your options (sound, motion, colours, swimmer), whether you have seen the quick tour, and the date the Krillsub app panel was last shown are saved in your browser's local storage under keys that start with ku:. They never leave your device unless you download them yourself from My record. Clearing your browser data, or using a private window, removes them.

Sent to our server when you play

Your answers. For each answer we receive the question, the text you typed, the mode and, in the daily set, the date. We add the answer to a running count for that question, which is how we can later show what share of players gave the same answer.
A one-way code instead of your address. So that one person cannot inflate a count, the server turns your IP address into a short code with a secret salt and a one-way hash. The code cannot be turned back into the address. It is stored with the question and the day, and with your final score in a daily set, so that we can say how many players you out-swam.
The AI referee. When an answer is not on our sheet, the question and the answer, and nothing else, are sent to an AI model through OpenRouter, which checks whether the answer is correct. The verdict is saved with the answer so the same answer is judged the same way next time.
Server logs. Like any website, our web server records requests (IP address, page, time, browser) for security and troubleshooting. The logs are deleted automatically after about two months.

Outside services

Google Analytics counts visits and game events (for example, a set started or finished) so we know which parts of the site are used. It sets cookies and receives your IP address and browser details. Google's privacy policy applies: policies.google.com/privacy.
Google Fonts provides the two typefaces on the site. Your browser downloads them from Google's servers.
Google Play. Links to our Krillsub app open Google Play and tell it that you came from this site and which link you tapped. Nothing else is shared.

There are no ads on Krillion Unlimited at the moment. If we add advertising, this page will be updated before it appears and will name the ad provider.

The contact form

Messages you send through the contact form reach our team with the text, the email address if you gave one, any images you attached and your IP address, which we use only to filter spam. The form uses a small puzzle solved by your browser instead of tracking captchas. We use your email only to reply to you and never add it to a mailing list.

Children

The game is suitable for all ages and asks for no personal information. We do not knowingly collect personal data from children. If you believe a child has sent us personal details through the contact form, write to us and we will delete them.

Your choices and rights

You can block cookies and analytics in your browser settings or with a blocker; the game works the same without them. You can ask us what we hold about you, or ask us to delete it, through the contact form. Because answers are stored only with a one-way code, we usually cannot link them back to a person.

Changes

If we change what we collect, we will update this page and the date at the top.
