Your Loyalty Card Data 

The first set of data will be collected by high street retailers through your use of loyalty cards. This includes

  • Items purchased (e.g. paracetamol)
  • Date of purchase
  • Location of the purchase (i.e. store postcode).

This will not include information on NHS prescriptions or any personally identifiable information, e.g. full name, postcode, ethnicity.

Note: Your loyalty card past purchase information will only be collected one time from the participating high street retailers. The CLOCS team will request your past purchase data from at most 6 years ago (depending on the high street retailer’s records and when you obtained a loyalty card) to the date you complete the consent form.
