Privacy Policy

Last updated: November 12, 2026. This policy covers the website krillion.free.

Stored in your browser

Your results, streak, settings and any dive in progress are kept in your browser's local storage under keys that start with kf:. They never leave your device unless you export them yourself with "Save as JSON" or "Save as CSV". Clearing this site's data in your browser deletes them.

Stored on our server

When you submit an answer, our server receives the prompt, the text you typed and the date. It uses them to score the answer and to count how often each answer is given, so that we can show what share of players chose the same one. To stop a single visitor from counting many times, we store a one-way salted hash of your IP address together with the prompt and the date. The hash cannot be turned back into your IP address. Like any web server, ours also keeps short-lived access logs for security and troubleshooting.

AI referee

If your answer is not on our answer sheet, the prompt and your answer, and nothing else, are sent to an AI model through OpenRouter to check whether the answer is correct. The verdict is saved so the same answer is judged the same way next time.

Analytics

We use Google Analytics 4 to understand how many people visit, which pages they open and how far they get in a dive. Google Analytics sets cookies and processes data as described in Google's privacy policy. You can opt out with the Google Analytics opt-out add-on or a content blocker.

Fonts

The Fredoka typeface is loaded from Google Fonts, which means your browser requests it from Google's servers and Google receives your IP address as part of that request.

Advertising

The site does not show ads at the moment. If that changes, this policy will be updated before any ads appear, including information about cookies and your choices.

Contact form

Messages sent through the contact form, including an email address if you give one and any screenshots, are delivered to our support inbox and used only to answer you and improve the game.

Children

The game needs no account and asks for no personal information. The contact form is optional.

To ask about your data or have something deleted, write to us through the contact form.
