Loyalty cards & retail tracking

Clubcard points bought with a detailed record of what you buy.

Understand it

Loyalty schemes trade a discount for a complete record of your shopping - what, when, where and how often. That record is valuable: it is analysed, and often shared with or sold to partners, building a picture of your household, health and habits.

How to spot it

The discount is real; the data collection is the price. Both are by design.

Close the gap

  1. Decide scheme by scheme whether the discount is worth the record.
  2. Use a separate email alias for loyalty sign-ups.
  3. Give the minimum - you rarely need to hand over a full, accurate profile.
  4. Check the scheme’s privacy settings and opt out of data sharing where offered.

What to do about it

There's no single off-switch for this. A tracker-blocking browser, refusing non-essential cookies, and the data-broker clean-up in your plan cut most of it down to size.
