Privacy notice

Version 2.2, 24 September 2026.

This website collects nothing about you unless you join Cannie or sign in. No cookies for reading, no trackers, no analytics, no third-party fonts or scripts. If you just look at the page, nothing about your visit is recorded by us.

If you join Cannie

What we collect: your email address, and the time you joined. If you take the short monthly survey about the supermarkets while you wait, we keep your answers with your waitlist entry. Nothing else.

Why: to email you when Cannie opens to you, with how to get your data from your loyalty cards, and to follow up while you're getting set up if it's gone quiet or something's gone wrong. Nothing else — no newsletter, no marketing.

Lawful basis: your consent, given when you press Join. You can withdraw it at any time by writing to [email protected].

Where it's held: by our website hosts, Cloudflare. Cloudflare is our processor and acts only on our instructions.

How long we keep it: when Cannie opens to you, your address becomes your sign-in; if you don't join, we delete it.

If you sign in

Signing in sends a one-time code to your email address and sets a cookie so you stay signed in on that device. That cookie does one job — remembering you've signed in — and is set by our web host.

Who we are

The data controller is Cannie Ltd, registered in England & Wales, company number 17340424. Registered office: 82a James Carter Road, Mildenhall, Bury St. Edmunds, England, IP28 7DE. Contact: [email protected].

Your rights

You can ask us what we hold about you, ask for a copy in a form you can take elsewhere, correct it, pause our use of it while something's sorted out, object to anything we do with it, or have it deleted. Write to [email protected] and we'll act on it, no questions asked. If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.
