So here's something that happens every single day.
You paste a client contract into ChatGPT to help draft a response. Your colleague uploads meeting notes to get a quick summary. Someone on your team asks Claude to review sensitive financial projections.
Totally normal stuff, right?
But here's the thing nobody is really talking about: where does all that data actually go?
This is bigger than you think
I came across some research recently that kind of blew my mind. 34.8% of what employees paste into AI tools contains sensitive data. That's up from just 11% in 2023.
Let that sink in. A 3x increase in one year.
And we're not talking about careless people here. These are smart, well-intentioned professionals sharing customer names, proprietary code, financial details, and strategic plans. Most of them just don't realize what they're doing.
You might remember the Samsung story from 2023. Engineers accidentally uploaded source code and confidential meeting notes to ChatGPT. The company had to ban external AI tools entirely after that.
Here's the weird part though. 73% of people say they worry about chatbot data privacy. Yet we keep pasting sensitive stuff anyway. Why? Because we don't actually understand what happens behind the scenes.
Let me break this down plainly
The official privacy policies are honestly designed to confuse you. So here's what's actually going on:
If you're on a free or standard plan (ChatGPT Free, Plus, or similar tiers on Claude and Gemini), your conversations may be stored, reviewed by human moderators, and potentially used to improve future models. Even if you delete a chat, it can stick around for up to 30 days for "abuse monitoring." Your data isn't truly private.
If you're on an enterprise tier, it's a different story. Most providers offer "no training on your data" guarantees at this level. ChatGPT Team, Enterprise, and Edu don't use your inputs to train models. Claude's enterprise offerings have similar protections. But you're paying significantly more for this privilege.
The uncomfortable truth? If you're using a free or standard subscription, treat every prompt like it could become public. Because functionally, it could.
The 5 things you should never paste
Here's a simple rule I use: if I wouldn't post it on LinkedIn, I don't paste it into AI.
1. Client or customer data. Names, contact information, account details, or any personally identifiable information. This one seems obvious but people do it all the time.
2. Proprietary code or algorithms. Your secret sauce shouldn't become training data for your competitors. Seriously.
3. Financial details. Revenue figures, projections, pricing strategies, or investment information. Even if you think it's harmless.
4. HR and personnel information. Performance reviews, salary data, or anything about specific employees. This can get you in actual legal trouble.
5. Strategic plans. M&A discussions, product roadmaps, or competitive intelligence. Keep the good stuff close to your chest.
How to use AI safely (without slowing down)
Look, the goal here isn't to avoid AI. I use it every day and I think you should too. The goal is to use it intelligently. Here's how:
Anonymize before you paste. This takes like 30 seconds. Replace "Acme Corp" with "[CLIENT]." Swap "$2.4M revenue" with "[REVENUE FIGURE]." Strip names, dates, and identifying details. The AI can still help you. It just doesn't need the real data to do it.
Use the right tier for the job. If your work involves genuinely sensitive information, push for enterprise access or look into locally hosted models. The cost is a fraction of what a data breach would run you.
Turn off training in settings. Most AI tools let you opt out of having your data used for model training. It's buried in settings, but it's there. Go do this today. Like, right after you finish reading this.
Create a team policy. If you lead a team, don't leave this to chance. Write down what's okay to share and what isn't. People will follow clear guidelines. They just need those guidelines to actually exist.
The bottom line
AI tools are genuinely useful. I'm not here to scare you away from them. But they're not confidential by design. Treating them like a trusted colleague who will keep your secrets? That's a mistake.
The question isn't whether to use AI. It's whether you understand the trade-offs you're making every time you hit "send."
Now you do.
