- The website offers an optional email newsletter for Boop release, compatibility, and support updates.
- The website may use PostHog product analytics only after cookie consent. The iOS app does not use PostHog or any analytics SDK.
- Boop is not a medical device. Outputs may be approximate and are not for diagnosis or treatment.
- Boop is independent and is not affiliated with, endorsed by, or sponsored by WHOOP, Apple, or Bevel.
- WHOOP names are used only to state factual device compatibility.
- WHOOP 4.0 is not yet supported.
- Derived estimates are distinguished from decoded observations and carry Boop algorithm-version metadata where supported (revision depends on the installed build).

- Boop Full includes dedicated Sleep, Recovery, Strain, Journal, Fitness, and longer-term insights.
- Apple Health can be set up later. Local strap processing continues without Health export.
- TestFlight shows the currently available build and its device requirements.
