Why should I find out what supermarkets know about me?

You should find out what information supermarkets that you've shopped with know about you, because the data that they store is often personal, and could be having material impacts on your life.

Mainly, because what happens to your data should be up to you.

Personal data that supermarkets typically store:

  • Contact details
  • Credit and debit card details
  • Name and address
  • Cookies & IP address
  • Tastes and habits
  • Economic, social and cultural information

Supermarkets also often supplement their customer data with data collected from elsewhere, such as the electoral roll, Land Registry, the Office for National Statistics and credit reports.

Seem excessive? It is. While collecting so much data may be beneficial to a supermarket, helping them make operational and product decisions, it puts you as a consumer at risk.

As well as many supermarkets selling this information to third parties, the industry also has a long history of data breaches.

You can find out what supermarkets know and are sharing about you by sending a subject access request at the top of this page.

What's that?

A subject access request is a written request that you send to a company asking for them to show you what personal information they have about you on their records. It's your right to decide what happens to your data under GDPR law.

How do I ask supermarkets for my personal data?

The easiest way to see what information they have is by sending a request through Rightly.


  • Get started above and select the supermarkets you'd like to ask
  • Enter your basic details for identification purposes
  • Send your request to all of the major supermarkets

They should confirm what they have and what they're doing with it within 30 days.

How long until a supermarket responds to my request?

After the supermarket has received your request, they have to reply in full within 30 days, or give a valid reason for asking for an extension. If this happens, our support team is here to help!

What if they don't reply?

Don't worry, they have to reply by law, thanks to your ‘right to access’ under GDPR. GDPR applies in the UK and EU.

What if I’m not sure if they have my data?

You can still ask them. If they don’t have it, they have to let you know.

Why Rightly?
