💎 Your data is a real treasure — for other people. Taken one by one, each piece seems harmless. Put together, they draw who you are: where you live, what you like, how much you earn, who you know, what you think. It's this profile that companies buy to target you with ads, that scammers exploit to trap you, and that you often give away for free without realising. Protecting your data isn't about "having something to hide" — it's about deciding who gets to know what about you. This course shows you how to take that control back, simply.
