Privacy policy
Updated
My Bio Age is built to be private by design. We believe your Apple Health data should stay on your devices unless you explicitly choose to share it. This policy explains what we collect, how we process it, and the controls you have. The health-data commitments below describe the current consumer app.
What we read from Apple Health
With your permission, the app can access VO₂max, heart rate variability (SDNN), resting heart rate, walking heart rate, heart-rate recovery, sleep records, and active energy, alongside other supported activity, body composition, respiratory, temperature, oxygen saturation, and optional blood-pressure measurements. It also reads your date of birth and biological sex, which age-adjusted and sex-specific comparisons need. These inputs support the MyBioAge Index™, recovery and other wellness scores, and trends. Availability depends on your devices, recorded data, and permissions.
What we write to Apple Health
With your permission, sauna and ice-bath sessions you log in the app, on Apple Watch or with a Shortcut are saved to Apple Health as workouts. The app does not write its scores, the MyBioAge Index™, cooldown estimates or laboratory results to Apple Health.
Apple Health data stays on your device. You can choose to share information yourself, such as by copying a Diagnostics report. The app does not upload your health history on first launch or through weekly uploads. You can change permissions at any time in the Health app.
How processing works
Scores are calculated on your device using Apple-supplied frameworks and our local models. Weekly digests are generated on-device and delivered via in-app local notification every seven days.
Optional cooldown recovery
In versions with “Estimate from workout cooldowns”, this optional setting reads exercise and cooldown workouts and recorded heart-rate samples with your Health permission. The app calculates the heart-rate drop from exercise end to one minute later on your device. Eligible estimates can contribute to HR Recovery, Recovery scores and the MyBioAge Index™. Days with heart-rate recovery readings already in Apple Health use those readings instead.
The app does not write its cooldown estimates to Apple Health. These records stay local unless you choose to copy and share a Diagnostics report. Disabling the setting clears its saved estimates; resetting cached Health data also clears them. The Index still uses only the most recent six months. Previously calculated recovery history can be used by the on-device AI Coach while the setting is enabled.
Laboratory records and extended history
In app versions with Laboratory results, you can select blood, urine and other laboratory PDFs from Files. Text recognition and review run on your device. My Bio Age does not upload the reports or send them to an external AI service. A cloud file provider may download a file you select before the app reads it.
Saved laboratory PDFs and results use iOS file protection and are excluded from device backups. You can correct or delete a report within Laboratory results; deletion removes the app’s copy, leaving your original in Files. Keep your originals. An eligible reviewed blood panel can provide a separate Laboratory PhenoAge estimate alongside the MyBioAge Index™. This does not establish greater accuracy or provide a diagnosis. Laboratory reports are not written to Apple Health or included in AI Coach prompts.
Versions supporting extended history can retain all available supported Apple Health history in a protected local archive for the AI Coach, subject to permissions and available records. That archive is excluded from backups. The MyBioAge Index™ remains limited to the most recent six months. Coach answers receive selected facts and summaries, rather than every measurement.
Home Screen widget
In versions with a Home Screen widget, adding it makes your dated Index, recent weekly trend and selected wellness scores visible on your Home Screen. The app shares only this summary with its widget through a protected local file excluded from backups. The widget does not read laboratory documents, coaching history or HealthKit. Resetting cached Health data clears the shared summary and requests a widget update; iOS controls when that update appears.
Diagnostics
In app versions with Settings › Diagnostics, that screen shows technical details about the Health data, scores and saved files on your iPhone, to help support answer questions. Nothing is sent. Only when you tap Copy report is a text report placed on your iPhone’s clipboard, and you decide whether to paste or share it. The report contains health values and scores and your age in whole years, but not your date of birth, laboratory report text, AI Coach conversations or the names of your Health sources.
Consumer app: no tracking or selling of health data
The consumer app does not use servers to store your health data. It has no advertising, tracking pixels, or analytics scripts. We will never sell, share, or monetise personal information or health data from the consumer app. Your health data stays on your devices unless you explicitly choose to share it yourself. App data and local caches remain on your devices under your control. The app is free forever and does not require an account.
Former My Bio Age Pro project
Update (October 21, 2026): The planned Pro offering has been retired. My Bio Age remains a free app with on-device health processing and AI. There is no planned Pro subscription or cloud upgrade.
If you previously used a Pro preview or have a question about a Pro account or record, contact [email protected]. This retirement notice does not confirm deletion of any existing account or record. Do not send health records, passwords or recovery keys in an enquiry.
Marketing website analytics
This website uses Simple Analytics to understand visits to pages such as our guides and product information. This is separate from the consumer app and does not give the website access to your Apple Health data. Website statistics include page views, referral sources, and general device and browser information. Simple Analytics states that it does not use cookies or store IP addresses. See its data collection documentation for details.
Clinical partnerships
We are developing a separate clinical AI product and seeking clinical development partners. The current My Bio Age app remains a consumer wellness product. The first clinical workflows and intended use will be defined and evaluated with clinical partners.
The intended architecture keeps AI inference on patient or clinic devices, without sending health records to external model providers for processing. Sharing between a patient and their care team is intended to be explicit and purposeful. Before clinical use, the product will need evaluation appropriate to its intended use and clear privacy information for that deployment. Learn more about our clinical partnership direction.
Partnership enquiries
When you email [email protected] about a clinical, investment or strategic partnership, we receive the contact details and message you choose to send, such as your name, professional email address and organisation. We use this information to respond to your enquiry. This correspondence is separate from the consumer app’s on-device health data. Please do not include patient information or medical records.
Contact and support
Need to delete or export your information? In the app, Settings › Data Controls › Reset all Health data clears the app’s cached Health data, then reads it again from Apple Health with the permissions you allow there, and you can delete an imported report within Laboratory results. For privacy or support requests, including enquiries about the former Pro project, contact [email protected]. We aim to respond to privacy requests within 72 hours.
Updates
We may update this policy as we introduce new features. The latest version is always available in the app and on this website. We will notify you in-app if the changes are significant.
