Using Health iAge means accepting these terms. The app is licensed for lawful personal use under Apple's standard Licensed Application End User License Agreement unless a custom EULA is presented (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). Software, design and content belong to or are licensed to AI Negotiator Technology Limited; Apple marks belong to their owners. Do not interfere with security, HealthKit or StoreKit, misuse another person's data or present estimates as clinical facts. Features and Apple services may change or become unavailable. To the extent allowed by law, the app is provided as is and as available, without a guarantee of accuracy, continuity or fitness; liability for indirect, incidental, special, consequential or punitive losses is excluded only where lawful. Mandatory consumer rights and liabilities that cannot be excluded remain intact. The provider is established in China; these terms select no exclusive court or dispute forum, and mandatory protections in your country apply. You may stop using the app at any time. Updated dates identify policy changes; material new health-data uses require another review. Contact service@healthage.cloud or 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.
Contact and privacy rights
Privacy requests go to privacy@healthage.cloud; support goes to service@healthage.cloud. We process the contact details and messages you provide to respond, protect the service, meet legal obligations and handle legal claims, relying on contract, legitimate interests, legal duties or consent as applicable. Messages are retained only as reasonably necessary; contracted email, hosting, security or professional providers may assist and may not use them for advertising. Google and our providers may process telemetry or messages internationally under applicable transfer safeguards. Subject to local law and exceptions, you may request access, correction, deletion, restriction or portability, object, withdraw consent or complain to a data-protection authority. We may need to verify a request and may be unable to identify earlier pseudonymous telemetry. Device-local health data is controlled on your device. No storage method is completely secure.
