About Cannie — who we are, how it works, and the promises we make
Cannie exists, for free, for its members.
We want you to get as much value from your own data as the retail industry already gets from it.
We are not a data business: we don't and will never sell your data. We store it safely and have developed the tools to help you understand what it's saying. It's yours, and we only ever show it to you.
We don't host adverts or have sponsored content. If we tell you something, it's always our impartial view based on facts.
Our founder has spent his career in the industry and knows this part of it back to front. He built these tools to help his family, and now they're available to anyone who logs in.
So yes, we've switched sides of the counter. For decades the data has flowed one way: from your basket to the supermarkets. Cannie puts it back in your hands.
The promises
We never sell your data
Not to the retailer, not to a brand, not to anyone.
You can see all of it, and leave whenever you like
Ask and we'll send you a copy of everything of yours we hold.
We ask before we touch anything sensitive
Health, medication, family matters: we won't show you any of it unless you ask.
No brand pays us to influence what you buy
If we suggest a cheaper or better option, it comes from the data and nobody paid us to say it.
It's free, and it stays free
Members don't pay to use Cannie.
We're not against your supermarket
We like supermarkets. We're just on your side of the counter when it comes to understanding where you get the best value and how to make better choices.
Real prices, not shelf prices
Every price we show is what was actually paid at the till by our members. The prices and offers are real.
We tell you what we know
If we're confident, we'll say so plainly. If we're not sure, we'll say that too, and ask you rather than pretend. When you correct us, we fix it.
