Use AI on Your Health Data Without Sending It to OpenAI
AI is great at finding patterns in health data. The catch is most AI health features upload your most sensitive data to a company's servers. Here's how to get the insight without giving up the privacy.
Where your health data goes with ChatGPT Health and Perplexity
ChatGPT Health (OpenAI) and Perplexity Health are real products that connect to Apple Health on your iPhone. They read your HealthKit data and process it on their servers to generate insights and answer questions about your health trends.
That processing happens under each company's consumer privacy policy, not HIPAA. That's a meaningful difference in how your data can be used, retained, and protected. Some people are comfortable with that trade-off. Others aren't. Neither position is unreasonable.
Data leaves the device
Health data is sent to company servers for AI processing. What gets retained and for how long depends on each product's privacy policy.
Consumer privacy policy
These products operate under consumer terms, not HIPAA or healthcare-grade data agreements. Read the policy if this matters to you.
The local-first alternative
AI Health Export's Free and Lifetime Export tiers take a different approach entirely. The app reads directly from Apple HealthKit and builds your export — a clean CSV of the metrics and time range you selected — entirely on your iPhone.
No account. No cloud sync. No ad tracking. Your health data doesn't go to our servers. The CSV file exists only on your device until you decide where, if anywhere, to send it. You can use it with ChatGPT, Claude, Gemini, Copilot, or any other AI tool — or just keep it as a local record.

Free vs Lifetime Export at a glance
Free: 7 days of data, up to 20 metrics, no account, no payment required. Your health data stays on your iPhone.
Lifetime Export ($14.99 one-time): All 172 metrics, any time range back to your earliest recorded data, lifetime access. Your health data still stays on your iPhone.
What about the built-in AI chat?
To be direct: AI Health Chat's in-app chat does send data off your device. When you ask a question in the chat, the relevant portion of your health data is sent to Google Gemini to generate a response.
Two things worth knowing. First, data is sent when you open chat and when you send a message, and an enabled monthly deep-dive summary also sends data on a schedule. Second, Google does not use paid API data to train its general models, which is a different data relationship than using Gemini directly through the consumer app.
If your goal is no health data leaving the iPhone, Free and Lifetime Export are the right choice. Export your CSV locally, then decide which AI tool (if any) you want to use with it. AI Health Chat is for people who want the convenience of in-app AI chat and are comfortable with the Gemini data relationship.
Free + Lifetime Export
Your health data stays on your iPhone until you choose to share it. Export CSV locally, then decide where (if anywhere) it goes.
AI Health Chat ($14.99/mo or $149.99/yr)
In-app AI chat via Google Gemini. Data sent when you open chat and when you send a message. Google does not use paid API data to train its general models.
You choose what you share
Whether you're exporting locally or using the in-app chat, you control exactly what gets included. AI Health Export never bulk-exports your entire health history without your input.
Pick your metrics. Choose only the data types relevant to your question. Want to analyze sleep trends? Include sleep stages. Not interested in sharing nutrition data? Leave it out. With 172 metrics available, granular selection means you share what you need, nothing more.
Set your time range. A week, a month, a year, or a custom range. You don't have to share your full history to get useful insights.
Face ID protection. Every export is gated behind Face ID. No one can pull your health data out of the app without your biometric authentication.
