Privacy

Your answers stay on your device, we collect nothing, and there is no account unless you decide you want one.

What is stored, and where

Your progress — which questions you have answered, which were right, which you flagged, and what you have asked the optional AI tutor — is stored in your own browser's local storage. It is not sent to us. Clearing your browser data clears it.

If you sign in, that same progress is additionally synced through a Firebase project so it follows you between devices. Signing in is optional and adds cross-device sync and nothing else. There is no profile, no marketing profile, and no advertising identifier.

What is never collected

• No analytics script of any kind. There is no page-view tracking and no session recording, which is why we cannot tell you how many people use the site.
• No advertising network, no remarketing pixel, no third-party embed.
• No email capture and no newsletter.
• No exam answers, scores, or results leave your browser.

Grading happens on your device, which is why it keeps working with the network off, and also why we have no pass rate to publish.

The optional AI tutor

Ms. Kaya does nothing until you turn her on, and she is not free in the way the rest of the app is. You supply your own MiniMax API key in Settings. That key is held in your browser's local storage and used to call MiniMax directly from your device. We do not provide a key, we do not proxy the request, and we cannot see yours. Every question, explanation and self-test in the app works without her.

Third parties

The app loads no third-party fonts, scripts or images. Everything it needs is served from the same origin, so opening the site does not tell any other company you were there.

Children

This is a study tool for adults preparing for a professional credential. It is not directed at children and we do not knowingly collect anything from them, because we do not collect anything from anyone.

Changes

If this ever changes, this page changes with it. There is no separate policy document that can drift out of sync with what the app actually does, because this page is describing the app and is rebuilt alongside it.
