Cookie policy
Last updated 23 October 2026.
This policy explains the cookies Mantlin uses. A cookie is a small file a website stores on your device. We keep our use of them to the minimum.
We only use essential cookies
Right now Mantlin uses only essential cookies. That means the login and session cookie that keeps you signed in and remembers your practice while you use the site. Essential cookies are needed to provide the service you have asked for. Under the UK’s cookie rules (PECR), essential cookies like these do not require your consent, so we do not show a consent banner for them.
We do not use advertising cookies today, and if that ever changes we will update this page and ask for your consent first, which is the same commitment our privacy policy makes. We use no third-party analytics cookies either, and we do not track you across other websites.
Settings kept on your device
The UK’s cookie rules cover more than cookies. They also cover other ways a website stores information on your device. Mantlin uses your browser’s own storage for five small things, all of them kept only on your device and never sent to us.
- Auto-continue. Whether questions move on automatically after you answer, so the site remembers the choice you made with the auto-continue switch. It stays until you clear it.
- Auto submit. Whether tapping an answer submits it straight away, or only selects it until you press Submit answer, so the site remembers the choice you made with the auto submit switch. It stays until you clear it.
- The auto-continue tip. A note that you have already seen the one-time tip explaining auto-continue, so it is not shown to you again, and so the first question of a test moves on by itself like the rest instead of waiting for you to press Next. It stays until you clear it.
- Repeat error count. If an error page appears, a count of how many times it has appeared in that browser tab, so we can offer different help when a problem repeats. It is deleted when you close the tab.
- New version reloads. The time the site last reloaded onto a new version in the browser tab you are using, and the times of its most recent automatic reloads, so the site never reloads itself in a loop or more than twice in half an hour. It is deleted when you close the tab.
None of these identifies you, and none of them is shared with anyone. They exist only to make the site work properly or in the way you have chosen, so like the login cookie they do not need your consent. You can clear them at any time by clearing the site data for Mantlin in your browser settings. If you do, auto-continue goes back to on, auto submit goes back to on, the tip may appear once more, and the first question of a test may wait for you to press Next again.
Usage analytics
We use Cloudflare Web Analytics to count page views. It has been on since 10 September 2026. It is cookieless by design: it sets nothing on your device, stores no identifier, and does not follow you to any other website. That is why it needs no consent banner, and why turning it on did not change what is stored on your machine. It tells us how many people read a page, not who they are.
If we add non-essential cookies later
We may one day add something that is not essential, such as a different analytics tool. That would be a non-essential cookie and it does require your consent. Before we switch anything like it on, we will:
- introduce a consent banner using a certified Consent Management Platform;
- ask for your consent before setting any non-essential cookie;
- let you change your choice at any time;
- update this policy to list each non-essential cookie and the third party behind it.
How to control cookies in your browser
You can control or delete cookies through your browser settings. Every major browser lets you see the cookies stored, delete them, and block cookies from some or all sites. Clearing a site’s data also clears the settings described above. If you block the essential login cookie, you will not be able to stay signed in.
