Safety first: settings to check and the traffic-light rule

Using Claude is about as safe as using email or online shopping, as long as you follow a few simple rules. Here they are.

The traffic-light rule

Before you type anything, think of traffic lights:

🟢 GO: fine to share

• Everyday questions (“What can I cook with leeks?”)
• Letters and emails, with private numbers removed
• General information about you (“I’m retired and live in Devon”)

🟠 THINK FIRST

• Other people’s personal details. Use “my neighbour” instead of their full name.
• Health questions. General questions are fine. Think about how much detail you really need to give.
• Work documents. Check your employer’s rules first.

🔴 NEVER share

• Passwords, PINs or security codes (including codes your bank texts you)
• Bank card or account numbers
• National Insurance, passport or driving licence numbers
• Anything you’d be upset to see made public

Golden rule: Claude will never need your passwords or bank details. If anything ever asks for them, even something that looks like Claude, stop.

Four settings to check today

Go to Settings. On a computer, click your name or initials at the bottom left, then Settings. In the app, tap the ☰ menu, then your name, then Settings.

1. Help improve our AI models (under Privacy) This controls whether your conversations may be used to help train future versions of Claude. Many people prefer to switch it off. Claude works just as well either way. It’s your choice.

2. Memory Claude can remember helpful things you’ve told it, across different chats. On makes it more personal; off is more private. You can change this any time. (More in Chapter 10.)

3. Your login security Claude uses your email or Google account to sign you in, so that account is your key. Make sure it has a strong password and two-step verification turned on (where you get a code by text or in an app as well as your password). If you’re not sure how, ask a family member or search “turn on two-step verification Gmail”.

4. Incognito chats When you start a new chat, look for a small ghost-shaped icon at the top right. It starts a private chat that isn’t saved to your history or memory. It’s perfect for one-off private questions.

Spotting AI-powered scams

Sadly, scammers use AI too. Their messages now look perfectly written, so don’t judge by the spelling. Judge by what they’re asking for:

🚩 Urgency: “Act now or your account will be closed” 🚩 Money or codes: paying, transferring, or reading out a code 🚩 Secrecy: “Don’t tell your bank / your family” 🚩 Odd payment: gift cards, cryptocurrency, a “safe account” 🚩 Too good to be true: guaranteed profits, surprise prizes

Fake voices: criminals can now copy a person’s voice from a short video clip. If you get a call from a “grandchild” or “child” in trouble needing money, hang up and call them back on the number you know. Many families now agree a secret code word for emergencies. It’s a lovely, simple idea.
