"Health AI Insight" ("we", "our", "us") is the developer of the "Health AI Insight" iOS application available on the Apple App Store. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

"Health AI Insight" reads health and fitness data from Apple HealthKit on your device. This may include: steps, active calories, heart rate, heart rate variability (HRV), resting heart rate, sleep stages and duration, blood oxygen, respiratory rate, body weight, BMI, lean body mass, mindfulness minutes, and workout data.
This data never leaves your device in raw form. It is processed locally to produce anonymised, aggregated summaries (e.g. "7-day average HRV: 62 ms") before any AI analysis takes place. We do not upload raw HealthKit records to any servers.
HealthKit data is used solely to provide the features you request within the app. It is never used for advertising, sold to third parties, or shared with data brokers. This is a strict Apple HealthKit requirement that we fully comply with.
When you request an AI insight or ask a question in chat, an anonymised, encrypted summary of your aggregated metrics is sent to an AI language model. There are two modes:
If you create an account or subscribe to a paid plan, we collect your email address and payment token (handled by Apple's in-app purchase system — we never see your full payment card details). We use this to manage your subscription and send product update emails.
To see which features are used and to keep the app stable, the app sends a small set of categorical usage events to the same backend that manages your plan quota — for example: completing onboarding, requesting or viewing an analysis or report, sending a chat message, selecting an AI provider (name only), viewing the subscription screen, or changing plan. These events carry your app version and the same pseudonymous device identifier used for quota enforcement — not your Apple ID, name, or email — and contain no health values, no message or report content, and no API keys. Our landing website separately uses Cloudflare Web Analytics — a cookie-free, privacy-first analytics tool that does not track individuals across sites.
We do not use your data for advertising, for building marketing or advertising profiles, or for sale to third parties.
HealthKit data exists only on your device — we have no copy to retain or delete. Account data (email, subscription status) is retained for the duration of your account plus 90 days after deletion, to comply with accounting obligations. Usage-analytics events are retained for up to 24 months, after which they are aggregated.
If you are located in the European Economic Area (EEA) or UK, you have the right to:
To exercise any of these rights, email . We will respond within 30 days.
In accordance with Apple's HealthKit developer guidelines:
Each of the above processors is contractually bound to handle your data in accordance with applicable data protection laws.
"Health AI Insight" is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.
We may update this Privacy Policy from time to time. Material changes will be communicated via an in-app notification or email at least 14 days before taking effect. Continued use of the app after the effective date constitutes acceptance of the updated policy.
