Cookies

Last updated: October 2026

Cookies are small files that a website stores on your device. Similar technologies, such as browser storage, can also store or access information on your device, and the same rules apply to them. This page explains the cookies and similar technologies used on this website and why. For how we handle personal information more generally, see our Privacy Policy.

Our approach

We keep cookies and similar technologies to a minimum. You do not need an account to use this website, so there are no login cookies. We do not use advertising or tracking cookies, and we do not sell your information. Because we do not use any cookies or similar technologies that need your consent, you will not see a cookie banner.

Essential cookies and storage

Some cookies and similar technologies are needed for the website to work, to keep it secure, or to provide a service you have asked for. These are strictly necessary, so they do not need your consent. We list them here so you know what may be set and why.

Our hosting provider, Vercel, may use cookies or similar technologies that are necessary to deliver the website, keep it secure and protect it from abuse.

We do not set any cookies of our own on this website.

The registration form temporarily saves what you enter in this browser tab so you can retry if your connection fails. The copy is removed when the submission or retry ends, and is normally cleared when you close the tab.

Our registration form is protected by Cloudflare Turnstile, our security-check provider, which helps tell genuine visitors from automated submissions. It checks information about your browser and connection, and may store or read information in your browser. Cloudflare uses this information to provide the security check and to improve Turnstile's bot detection, as explained in its Turnstile Privacy Addendum. The check is strictly necessary to protect the form.

Website statistics

We use cookieless website statistics to understand basic things, such as how many people visit and which pages are popular. Our hosting provider also provides these statistics. They do not set any cookies, and we do not use them to identify individual visitors.

You can switch website statistics off at any time on our Website statistics page. For website statistics, the only setting we save in your browser is your choice to switch them off. It contains no identifier and stays until you switch statistics back on or clear this website's stored data. If your browser sends a Global Privacy Control signal, statistics are off automatically.

Managing cookies

You can control or delete cookies and stored website data through your browser settings, including blocking them. Your browser's help pages explain how. If you block the technologies needed to provide or protect the registration form, you may be unable to send it. You can still contact us by email at numberphonics@rethinkmaths.co.uk.

Changes to this page

We will update this page if the cookies or similar technologies we use change, and update the date above. If we ever use cookies or similar technologies that need your consent, we will ask for it first.
