Support replies are in English only; we aim to respond within 48 hours at service@healthage.cloud. Describe your device model, OS/app version, a non-sensitive error and reproduction steps. Do not send health values, medical information, identifying screenshots, passwords, verification codes, payment-card details or transaction identifiers. Complete onboarding, choose Apple Health read permissions and allow local calculation to finish. For unavailable results, check recent supported data, permissions and coverage, then reopen and refresh. Coverage is not medical accuracy. Privacy requests: privacy@healthage.cloud.
Eligibility and wellness limits
Adult Health Age supports ages 18–79. Ages 14–17 receive limited youth guidance without an adult Health Age, age difference, trend ratio or younger/older result; other unsupported or unknown ages receive no adult estimate. The app is not intended for children under 14; obtain parental authorization where local law requires it. Outputs are provisional wellness estimates, not medical advice, diagnosis, treatment, disease detection, biological/cellular age or lifespan predictions. The method has not been externally calibrated to a population and does not rank users. Functional Age excludes birth date and calendar age from its calculation; insufficient evidence can leave a gap. Never delay medical care or use results for emergencies. For an emergency, contact local emergency services.
Health data on your device
Health iAge is provided by AI Negotiator Technology Limited, established in China. With the read permissions you choose, Apple Health information is processed on your iPhone to calculate Health Age, body function, trends and factor contributions. Health iAge does not write to Apple Health, requires no account and has no developer-operated health-data backend. Health samples and calculated results are not uploaded to our notification service or Firebase telemetry. Limited, old or unavailable data can prevent an estimate; denied read access cannot reliably be distinguished from missing samples.
Apple Watch and sharing
Apple Watch receives a minimal derived snapshot through Apple's paired-device connectivity, not raw Health samples, date of birth, biological sex or detailed sleep, heart-rate or HRV values. Open and refresh Health iAge on iPhone, then open the Watch app; check or restore the subscription if required. Complications can be seen by anyone who can see your watch face. Optional sleep estimation uses reduced sensor summaries that remain on your devices. Sharing begins only when you choose a destination in Apple's share sheet; the recipient's privacy terms then apply.
Subscriptions and billing
Health iAge+ offers monthly and annual auto-renewable subscriptions through Apple. Apple shows the controlling localized price, period and eligible offers before confirmation. A seven-day introductory trial is available only when Apple confirms eligibility; installation, onboarding or Health access does not start it. A subscription starts only after confirmation in Apple's purchase flow and renews unless cancelled through Apple. In Settings → Subscription, use Restore Purchases or Manage Subscription with the purchasing Apple Account. Apple handles billing and refunds at https://reportaproblem.apple.com/. Deleting the app or local data does not cancel a subscription or erase Apple's transaction records.
Local storage and deletion
Local retention is approximately 180 days for retained source samples, 35 days for intraday aggregates and up to five years for daily or weekly aggregates. Report history is limited to 840 hourly, 1,830 daily and 265 weekly points, and weekly factor history to 53 points. Optional sleep estimation keeps reduced sensor evidence for 72 hours and inferred sessions for approximately 180 days. Raw accelerometer readings and raw heart-rate samples are not retained in the persistent cache. Local health files use iOS Data Protection and are excluded from device backups. Deleting local health data clears the app's cache and history and returns it to onboarding; it does not delete Apple Health source data, revoke permissions or cancel subscriptions.
