We make things simple
You install a new app and the very first screen is warm and helpful. "Find Friends" it says, with a big button underneath: Allow Contacts. It feels like a small favour to yourself, so you tap it. What did I just hand over? Every name and number stored in your phone. Your relatives, your doctor, โฆ
We think of privacy as a personal choice. My phone, my data, my decision. Then we tap "allow access to contacts". And quietly make that decision for everybody else in it. Whose data is in my address book? Not yours. Your mother's number is her number, not your property. Your accountant gave you his details โฆ
Most of us have received that forward warning about a WhatsApp hack. Usually it is nonsense. This one was not, and the number is genuinely hard to take in. What was the number again? Roughly 3.5 billion accounts. That is not a typo, and it is not a subset. It is close to every WhatsApp โฆ
"It's just who I messaged, not what I said." Almost everybody says this, and it sounds reasonable. Let me show you why it falls apart. What can four messages reveal? Picture two ordinary days on somebody's phone. Message one goes to a divorce lawyer. Message two goes to an apartment listing site. Message three goes โฆ
We picture tracking as somebody reading what we write. So we watch our words, and feel careful. The truth is that your silence is just as readable. What can my habits give away? When you are online and when you are asleep. Which contacts get an instant reply and which wait until evening. Who you โฆ
Think about a single morning of phone calls. Not the words in them, only the numbers dialled. That short list can say something you have not told a soul. What do four calls look like from outside? The first call goes to an oncology clinic. The second goes to your partner, and it is longer โฆ
We download free apps without a second thought. Free feels like a gift, and gifts do not need examining. Then you notice the company behind it is worth billions. Something does not add up. What is the question I should be asking? Ask it every single time: how does this make money? Servers cost money, โฆ
You deleted Facebook years ago. You never touched Instagram either. So Meta has nothing on you, right? Sadly, that is not how it works. How can they have my details if I never signed up? The moment a friend lets an app "find contacts", your details leave their phone. Your name, your number and your โฆ
Your phone does not need to follow you around with a map open. It only needs to notice where it sits still. What does my phone's location really give away? Where your phone rests every night is your home. Where it rests from nine to five is your work. That is your address and your โฆ
Somebody always says it in the group chat. Signal and WhatsApp use the same encryption. So they must be equally private. It is a fair thing to assume. The answer is not in the messages at all. Are the messages themselves really the same? Both apps scramble your messages end to end. That means only โฆ
