Cookies policy
Last updated 21 May 2026
This policy explains how Optimal Group Ltd (“Optimal Health”, “we”, “us”) uses cookies and similar technologies on optimalhealth.co.uk. It sits alongside our privacy notice, which has the wider picture on how we handle personal data.
What is a cookie?
A cookie is a small text file a website places on your device to remember something about you between page loads or visits. The same idea also covers local storage, session storage, and a handful of related browser technologies; we group all of them under “cookies” in this policy.
The categories we use
Strictly necessary
These cookies are required for the website to function. Without them the booking form can’t submit, the account routes can’t sign you in, and the cookie banner can’t remember your choice. We do not ask for consent for strictly necessary cookies — they are part of the service you asked for. We use them for:
- Firebase Authentication session (after you sign in)
- Cross-site request forgery protection on forms
- Recording your cookie-preference choice
- The shopping-basket-equivalent for multi-step booking flows
Analytics and performance
These cookies tell us anonymously which pages people visit, how they got there, and where things break. We use them to improve the site and fix problems. They never identify you to us, and we never join the data with your booking or account record. Currently the site uses none of these — we’ll update this section if that changes.
Marketing
We do not run any third-party advertising cookies on this site. Period.
Cookie consent
Today this site sets only strictly-necessary cookies, so no consent banner is shown. If we add analytics or any non-essential cookies in future, we’ll ask for your consent before they are set and update this policy with the specifics. We’ll also add a preferences link in the footer so you can revisit your choices at any time.
Third-party services
The site runs on Firebase Hosting. Firebase sets a couple of technical cookies that help with hosting, load-balancing and abuse protection. These are strictly necessary — you can read Google’s policy at policies.google.com/technologies/cookies.
Controlling cookies in your browser
Modern browsers let you block or delete cookies, including for individual sites. The downside is that blocking strictly necessary cookies will stop parts of this site working. Browser-specific instructions:
Changes to this policy
We’ll update this page when we add or remove a cookie category, change a third-party service, or when the law changes. The “Last updated” date at the top will tell you when the most recent change was made.
