AI Privacy Starts With Other People's Data

"I've got nothing to hide."

It is one of the first things many people say when privacy comes up. And fair enough. If you are not doing anything dodgy, why worry?

But the moment you use AI in a business, it is worth stopping to think for a second.

Because the data you paste into a chatbot is often not really yours to share.

Say a customer sends through their details for a quote, and you paste the whole thing into ChatGPT to write a tidy reply.

Quick and easy.

The catch is that those details were never really yours to hand over.

They belong to your customer. "Nothing to hide" misses the point, because it was never your secret in the first place.

We do not control what happens later

For the next part, I will put on my tin foil hat for a moment.

We do not really know what every AI company will do with every kind of data in the future. Sell it for ads? Who knows.

But we do know this: once sensitive information leaves your environment, you have less control over it.

In 2025, a US court ordered OpenAI to keep ChatGPT logs, including deleted ones. And the biggest names in tech are still not unhackable. Leaks and misconfigured apps happen.

That does not mean you should panic.

It means you should give it half a thought before you paste.

The first open door

So what can you do?

Start with the simplest fix: anonymise sensitive data yourself.

Remove names, phone numbers, addresses, order numbers, client details and anything else that does not need to be there. The AI does not always need the full story to help you write a better reply.

Then check your tools.

If the provider gives you an option to stop your input being used for training, turn it off. If you are working with sensitive data, use a business plan or a cloud provider that offers zero data retention. If the work is truly sensitive, use local models where you can.

Same tools, a bit more thought

None of this is a reason to fear AI.

I use it every day.

But there is a big difference between using AI thoughtfully and casually pasting client data into whichever chatbot happens to be open.

Privacy is not just about protecting yourself.

In business, it is often about protecting people who trusted you with their information first.
