Your Clubcard Is Spying On You 7 DISTURBING Things Tesco Knows!

Описание: Your Tesco Clubcard isn't just tracking your groceries, it's building a detailed profile of your health, finances, and lifestyle that gets shared with hundreds of companies. Over twenty three million British households carry one, making it one of the most powerful surveillance systems ever created.

This investigation reveals exactly what Tesco knows about you through Clubcard data and where that information actually goes. You'll discover how dunnhumby scores every product you buy across fifty dimensions, why your shopping basket can predict health conditions up to eight months before diagnosis, and how your purchase data gets shared with Facebook, Google, Sky, and Virgin Media to target advertising directly at you.

We break down the uncomfortable mathematics behind the loyalty scheme and reveal how basic Clubcard points give you roughly one percent back while dunnhumby generates hundreds of millions in revenue from selling insights about your behaviour. The script examines real security breaches including the twenty twenty incident where six hundred twenty thousand accounts were compromised, explores the Cancer Loyalty Card Study using shopping data to detect ovarian cancer, and explains why privacy advocates call this system mass scale surveillance that turns privacy into a luxury only the wealthy can afford.

From the nineteen ninety five launch that helped Tesco overtake Sainsbury's within a month to the twenty twenty five rollout of hyper personalised pricing, this is the complete story of how a simple loyalty card became a cross platform data empire.

The Brit Basket With George covers British consumer issues, retail investigations, and how major UK companies actually operate behind the marketing.
