IMO Class 7 Practice Quiz · doty.gg

This is a free maths-practice website for students. We try to collect as little information as possible and we never sell anyone's data.

What we store

• The username and display name you choose.
• Your password, stored only in an encrypted (hashed) form — we can't read it.
• A security question and answer (also hashed) so you can reset a forgotten password.
• Your quiz progress and scores — which questions you answered and how you did.

We do not ask for your email address, phone number, home address, or real full name. You can use a nickname as your display name.

Why we store it

Only to let you sign in on any device, save where you left off, and show you your past results. That's it — no advertising, no tracking across other websites.

For parents and teachers

This tool is intended for school-age students practising mathematics. We deliberately avoid collecting personal contact details. If you would like an account and its data deleted, contact the site owner and we will remove it.

Cookies & tracking

We use one piece of local browser storage to keep you signed in. There are no third-party advertising or analytics trackers.

Data deletion

To have an account and all its quiz data permanently deleted, contact the site owner.
