Geureut tests run in your browser. Your answers are scored on your device and the result is shown only to you.

What we store, and only if you agree

Before the IQ test starts there is a box, ticked by default, to add your anonymous answers to our calibration data. If it stays ticked, when you finish we store:

Item	Example
Which questions you saw	m014, s022, v003 …
Right or wrong, time taken, timed out or not	1, 23 s, no
Page language, test version, total minutes	en, 1, 24
Your estimated ability and its standard error	0.84, 0.29
Date stored, and country from the network edge (two letters)	2026-11-03, AU

We do not store your name, email, IP address, cookies or any account. A record cannot be linked back to you. Untick the box and nothing is sent.

Why

Only to estimate how hard each question really is and where the average lies, so that scores become more accurate. We never sell or share this data, and use no advertising or analytics trackers.

On your device

A test in progress is kept in your browser’s local storage so you can resume within 12 hours. It is deleted when you finish or start over.

Where it is kept

Cloudflare (D1 database) on guud’s account. Because the records are anonymous, we cannot look up one person’s answers. Questions: hello@guudgood.com
