What happens to student data

Every school tool says it “takes privacy seriously”. That is not the useful question. The useful question is: where does the data go? With AIproff the answer is short — nowhere.

Not a promise, an absence of server

All the grading happens inside your phone's browser: the camera image, reading the bubbles, working out the score, and the voice that says it. There is no account, no login, and no address a picture of a test could be sent to.

The difference matters. A promise not to use your data depends on whoever made it continuing to keep it. Having nowhere to send it is a property of the tool — and you can check it by putting the phone in airplane mode and grading a whole test that way.

Where things are stored

• Tests, the answer key, and the scores live in the browser's own storage, on your device.
• The camera image is never saved: each frame is read and discarded.
• Your preferences — voice, language, theme — stay there too.

What you give up for it

The other side is worth saying, because it is real. With no server there is no automatic backup: if you change phones, clear the browser's data, or uninstall, the saved sessions are gone. There is no recovering them, because we hold no copy.

You also cannot start grading on one device and finish on another, or share the class summary with another teacher through the app itself. Those are exactly the things a server would bring — along with the obligation to store student data somewhere.

If your browser is short on space, it may clear data from sites you have not used in a while. Before you close out a class, write the scores down where you already write them.

What this means for the school

In practice, using AIproff does not create third-party processing of personal data: the data never passes through us at any point. What still applies is the ordinary care about the device itself — a locked screen, and the same prudence you already have with your grade book.
