This Cookie Policy explains how Jack's Burger Franchises Ltd (“Jack's Burger”, “we”, “us”, or “our”) uses cookies and similar technologies on this website. For how we use the personal data behind your account and orders, see our Privacy Policy.
What are cookies?
A cookie is a small text file a website asks your browser to store on your device, so it can recognise you on your next request — for example, to keep you signed in. We also use similar technologies such as your browser's local storage, which lets the site save small pieces of information (like your basket) on your device. In this policy we use “cookies” as a shorthand for both.
Cookies and storage we use
We keep this to the essentials. Here is everything the website stores on your device.
Strictly necessary
These are required for the site to work — they let you sign in and place an order. The session cookie is set by our account service on a separate host from this website, and is sent back to that service on each request. They can't be switched off from within the site.
| Name | Type | What it does | How long it lasts |
|---|---|---|---|
| better-auth.session_token | Cookie (our account API host) | Keeps you signed in after you log in or create an account, so your basket, saved details, and order history follow you around. It is set by our account service on a separate host from this website (a cross-site cookie) and is required to sign in and place an order. The website's own scripts can't read it. | Up to 15 days, then it expires |
Functional and preferences
These aren't used to track you — they are stored locally in your browser to remember your choices and make the site nicer to use. They stay on your device and aren't shared with anyone.
| Name | Type | What it does | How long it lasts |
|---|---|---|---|
| theme | Local storage | Remembers whether you chose the light or dark appearance so the site opens the way you left it. | Until you clear it in your browser |
| jb.cart.v1 | Local storage | Saves your basket — your chosen branch, whether it's delivery or collection, and the items and options you've added — so it's still there if you come back or open another tab. | Until you clear it or empty your basket |
Third-party requests
When you pay for an order, our payment provider handles the card details securely and may set its own cookies to process the payment and prevent fraud. Those cookies are governed by the provider's own privacy and cookie notices.
Our branch map loads its map imagery from a third-party mapping service. Loading those images means the service can see your device's IP address, as it would for any image on the web, but the map does not place any cookie or storage of ours on your device. The fonts you see are served from this website, so viewing the site does not send requests to any font provider.
What we don't use
We do not use advertising cookies or any cross-site tracking, and we do not run third-party analytics or product-tracking tools on this website. We don't build advertising profiles or sell your browsing data. Because the only cookies we use are strictly necessary and the rest is local preference storage, we do not show a cookie consent banner.
How to control cookies
You can view, block, or delete cookies and clear local storage through your browser's settings — every major browser lets you do this, and its help pages explain how. You can also browse in a private or incognito window, which discards this storage when you close it.
Please note that blocking the strictly necessary items above will stop you from signing in and completing an order, and clearing your storage will sign you out and empty your saved basket.
Changes to This Policy
We may update this Cookie Policy from time to time. When we do, we will revise the “Last updated” date above.
