Terms of Service

Welcome to 100Years ("the App"). The App is developed and operated by Jianwu Gao, an individual developer. Fresh onboarding asks you to accept the current Terms and Privacy Policy. If an existing user dismisses a later policy update, local features remain available; accepting the current version is required before future cloud data egress or a new purchase. We may revise these terms using an explicit version and in-app notice. Review the current version before granting a capability that requires consent.

100Years is a general-wellness app for adults ages 18–120. It provides: • Deterministic lifespan and health-signal estimates from available inputs • Health data tracking, sleep and workout summaries • On-device report parsing and data export • Optional AI explanations through an installed on-device model or a provider you configure The estimates are not clinically validated and do not constitute medical diagnosis, treatment advice, or a guarantee of lifespan. Consult a qualified medical professional for health concerns.

Lifetime Purchase 100Years offers one non-consumable lifetime purchase. It removes the daily limit on user-initiated AI analyses and unlocks PDF export and complete prediction history and trends. It is not a subscription and does not include third-party services, API keys, quotas, or permanent model availability. Free Access Core features, deterministic results, medical report imports, body-composition screenshot imports, on-device models when installed, and BYOK provider configuration remain available without purchase. Restoration and Refunds Restore Purchases verifies the lifetime purchase with Apple and creates no new charge. A refund returns the App to free access; existing stored records remain readable and raw JSON/CSV export remains available. Deleting local account data does not cancel, refund, or remove Apple purchase history.
