Terms of Use

Wellness product, not medical advice

BodySignal provides personal wellness evidence based on patterns in Apple Watch data. It does not provide medical advice, diagnosis, treatment, prevention, screening, or emergency monitoring. Do not use BodySignal to make urgent or medical decisions.

No emergency use

BodySignal is not intended for emergencies. If you believe you are experiencing a medical emergency, contact local emergency services.

Historical findings

BodySignal may compare later sleep with your typical sleep timing. A historical finding is an observed association in your own data, not proof that one behavior caused another. BodySignal may show that there is not enough comparable data instead of producing a finding.

Personal experiments

The current experiment asks whether avoiding caffeine after 2 PM is associated with different sleep outcomes over 14 assigned days. Usual-routine days do not require you to consume caffeine. Results may indicate a possible benefit, possible negative effect, no meaningful difference, an inconclusive result, or not enough usable data.

Experiment results are personal observations from a short protocol. They do not establish medical causation and may be affected by Watch wear, data availability, illness, travel, routine changes, or other factors.

Data availability and accuracy

BodySignal depends on Apple Health and Apple Watch data that may be incomplete, delayed, duplicated, or inaccurate. Eligibility and results are not guaranteed. Consistent Watch wear improves data completeness but does not guarantee a finding or a particular verdict.

One Sleep Experiment purchase

One Sleep Experiment is a one-time in-app purchase that unlocks the current caffeine experiment once after Apple verifies the transaction. The localized price is shown by the App Store before purchase. Eligible purchases can be restored using the in-app Restore Purchases action.

BodySignal Founding Annual

BodySignal Founding Annual is an auto-renewable annual subscription. It unlocks the current experiment and future BodySignal experiments while the subscription is active, if and when those experiments are released. It does not promise a specific number, schedule, or library of future experiments.

Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless you cancel it in your Apple Account subscription settings before renewal. The price, duration, and billing terms shown by the App Store at purchase control the transaction.

Cancellation and refunds

You can manage or cancel an annual subscription through your Apple Account subscription settings. Purchases and refund requests are handled by Apple under Apple’s policies. BodySignal does not process payment-card charges or refunds directly.

Acceptable use

You are responsible for using BodySignal safely and for interpreting its findings within the stated limitations. Do not use the app as a substitute for professional healthcare or to encourage another person to consume caffeine or change medication.
