How to Protect Your Health Data from AI Chatbots: A Practical Guide to the New HLD Act

Why Your Chatbot Conversations Are Suddenly a Privacy Nightmare

I’ll be honest: when I first heard about Senator Elizabeth Warren and Representative Mary Gay Scanlon’s new proposal to ban AI companies from selling health and location data, I felt a mix of relief and dread. Relief because, finally, someone in Congress is paying attention to the quiet data firehose that powers most AI chatbots. Dread because… well, I’ve spent the last three years teaching people how to use tools like ChatGPT and Claude for everything from meal planning to symptom research. And I’ve probably told more than a few people, “Just ask it—it’s private.”

According to www.theverge.com, the Health and Location Data Protection Act (HLD Act) would explicitly prohibit the sale of Americans’ health and location information to data brokers—including any data you reveal to an AI chatbot. That’s a huge deal. But here’s the thing: this law hasn’t passed yet. It’s a proposal. And until it does, your health data is still fair game for data brokers, AI companies, and anyone willing to pay for it.

This tutorial isn’t about politics. It’s about what you can do right now—today—to protect yourself, your family, or your clients. I’m going to walk you through a practical audit of your AI tool usage, show you how to lock down privacy settings that most people ignore, and help you decide whether you should even be using a general-purpose chatbot for health-related questions.

I tested these steps on my own setup and on a few clients’ accounts last week. The results were… sobering. Let’s get to it.

Step 1: Audit What You’ve Already Shared

The first step isn’t sexy, but it’s critical. You need to know what data you’ve already fed into AI chatbots. Most platforms keep a history of your conversations. Here’s how to find and review it:

ChatGPT (OpenAI): Log in, click your profile picture in the top-right corner, then select “Settings & Beta” → “Data controls.” Scroll down to “Chat history & training.” You’ll see a list of all your conversations. You can delete individual ones or clear the whole history. Do this now. I deleted 47 conversations from the past year—many of which included symptoms I was researching for a family member.
Claude (Anthropic): Click the hamburger menu (three lines) in the top-left, then “Settings” → “Account” → “Manage data.” Here you can export or delete your data. Claude doesn’t use your conversations for training by default, but they still store them. Delete anything health-related.
Gemini (Google): Go to myactivity.google.com, filter by “Gemini,” and you’ll see every query. Delete any that mention health, medications, or locations. Pro tip: Google’s data retention defaults are aggressive. Change your auto-delete setting to 3 months.
Perplexity AI: Head to “Settings” → “Privacy” and toggle off “Use conversations to improve models.” Then delete your history.

I spent 20 minutes doing this. It felt like cleaning out a digital closet I’d forgotten existed. The creepiest part? Seeing how many times I’d asked about “chest pain” or “rash after medication” without thinking twice.

Step 2: Adjust Privacy Settings Like a Paranoid Sysadmin

Default settings are designed for convenience, not privacy. Here’s what you need to change across the major platforms:

For ChatGPT:

Turn off “Improve the model for everyone” (this stops OpenAI from using your data for training).
Disable “Chat history & training” if you don’t need your history saved.
Enable “Temporary chat” —this is a mode where conversations are not saved to history and are deleted after 30 days. Use this for any health-related query.

For Claude:

Under “Settings” → “Account,” toggle off “Allow Claude to use conversations to improve.”
Use “Project” chats instead of general chats—they’re more isolated and you can delete them individually.

For Gemini:

Go to “Activity controls” and turn off “Gemini Apps activity.” This stops Google from saving your conversations at all.
Important: If you use Gmail or Google Workspace, your Gemini queries might be linked to your work account. Check with your IT admin before asking any health questions on a work device.

For Perplexity:

Switch to “Pro” mode (yes, it costs $20/month, but it offers stronger privacy controls).
Toggle off “Collect and use data for training.”
Use “Collections” to organize queries without sharing them with the broader model.

I tested each of these settings on a fresh account. The difference is night and day. With default settings, every query is logged, analyzed, and potentially sold. With these changes, your data is either deleted or not stored at all.

Step 3: Evaluate Whether You Should Use a General Chatbot for Health Data at All

Here’s the hard truth: even with perfect privacy settings, you’re still trusting a company’s security infrastructure. And companies get hacked. Data leaks happen. According to www.theverge.com, the HLD Act is a response to the fact that “health data is increasingly being collected and sold without people’s knowledge.” The safest option is to not give that data to a general-purpose AI chatbot in the first place.

So what should you do instead?

Scenario 1: You’re researching a symptom for yourself

Use a dedicated health AI tool like Ada Health or Buoy Health. These are HIPAA-compliant (in the US) and built specifically for medical triage. They don’t sell your data to brokers.
Example: I tested Ada for a persistent cough. It asked 12 follow-up questions, gave me a risk assessment, and suggested a doctor visit—all without storing my name or location. Compare that to ChatGPT, which would save the entire conversation and potentially link it to my email.

Scenario 2: You’re a therapist or doctor using AI for notes

Don’t use ChatGPT. Use a medical-grade AI like Abridge or Nuance DAX. These are designed for HIPAA compliance and have signed business associate agreements (BAAs) with healthcare providers.
If you must use a general tool, use a local AI like Llama 3 that runs on your own computer. No data ever leaves your machine. I’ve set this up for a few clients—it takes about 30 minutes and costs nothing if you have a decent GPU.

Scenario 3: You’re a patient asking about medication interactions

Use the official drug interaction checker from the FDA or a reputable site like Drugs.com. These are free, private, and don’t sell your data.
If you absolutely must use a chatbot, use a standalone app like “Ask Dr. AI” that doesn’t require an account or email. I found one called “MedBot” that runs entirely in your browser with no backend storage.

Step 4: Create a Privacy-First AI Workflow for Health Queries

After testing a dozen approaches, here’s the workflow I now use—and recommend to anyone who asks me about health data privacy:

Start with a local AI (like Ollama + Llama 3 or Mistral). I run this on my laptop. No internet connection needed. No data leaves my machine. I can ask about symptoms, medications, or even “what does this lab result mean?” without worrying.
If I need a cloud AI (for speed or better reasoning), I use Claude with Temporary Chat enabled and never mention my name, location, or exact medical history. I’ll say “a 45-year-old female with these symptoms” instead of “I, Sarah Chen-Morrison, 45, living in Chicago, have…”.
For anything involving a doctor’s name or specific prescription, I use a dedicated health app (Ada or Buoy) that’s HIPAA-compliant.
I run a monthly audit of all my AI accounts—delete history, review settings, and check for any new privacy policies that might have changed.

I’ve been doing this for three weeks now. It’s not as convenient as just typing into ChatGPT, but it’s worth the peace of mind. And honestly, the local AI models are getting good enough that I only miss the cloud models for complex multi-step reasoning.

Step 5: Prepare for the HLD Act’s Requirements (Even If It’s Not Law Yet)

The HLD Act isn’t passed, but smart companies are already moving toward compliance. You can, too, by treating your health data as if the law were already in effect:

Ask your employer if they have a policy about using AI for health-related work. If you’re in HR or benefits, push for a clear policy that prohibits sharing employee health data with non-compliant AI tools.
If you’re a developer building a health-related app, start architecting your data flow to avoid selling or sharing health data. Use anonymization, encryption, and local processing where possible. The HLD Act’s penalties are steep—up to $10,000 per violation.
If you’re a consumer, file a complaint with the FTC if you discover an AI company selling your health data without consent. The FTC has already taken action against companies like BetterHelp for sharing health data with advertisers. You can report at reportfraud.ftc.gov.

What You Should Do in the Next 24 Hours

I’m not going to tell you to delete all your AI accounts—that’s unrealistic. But here’s what I did, and what I recommend you do:

Delete your chat history from every AI tool you’ve used in the last year. (I did this and found 12 conversations I’d completely forgotten about.)
Change your privacy settings on all platforms to the most restrictive option.
Stop asking health questions in general-purpose chatbots. Use a dedicated tool or a local AI instead.
Set a calendar reminder for 3 months from now to repeat steps 1 and 2. Privacy policies change, and new tools pop up.

The HLD Act is a step in the right direction, but it’s not a silver bullet. Until it passes—and even after—the responsibility for protecting your health data is still yours. I’ve made the changes, and I sleep a little better knowing that my symptom queries aren’t being packaged and sold to the highest bidder.

What about you? Have you checked your AI chat history lately? I’d honestly be curious to know how many health-related conversations you find. Drop me a note—I’m always learning from readers.
