Privacy Policy

ohmybody · Last updated October 7, 2026

ohmybody keeps your health data on your device. This policy describes what ohmybody accesses, what stays on your device, and the choices you control.

Apple Health Access

  • ohmybody requests read access to workouts, workout routes and distance, Activity Rings, exercise, steps, daylight, sleep, heart, respiratory, blood oxygen, body measurement, energy, skin temperature, and date of birth data. Date of birth is used only to estimate the heart-rate zones on a workout detail.
  • Heart access also covers the beat to beat heartbeat recordings and the Recovery HRV readings your Apple Watch saves. ohmybody uses them only on your device to estimate Stress and to show Recovery HRV on the HRV page.
  • The optional Workout Metrics permission adds the extra numbers shown on a workout detail: cardio fitness, running and cycling power, cycling cadence, swim stroke count, and the step count used to derive foot cadence. You can turn it off in Data > Permissions.
  • ohmybody requests write access only when you choose to save a weight or body-fat measurement from the Basics detail screen, or an effort rating from a workout detail screen. If you turn on Auto-Apply Effort, ohmybody can also write a predicted rating to a recent unrated workout.
  • The only data ohmybody writes to Apple Health is the weight and body-fat measurements you enter, and the workout effort ratings you or Auto-Apply Effort save. ohmybody does not write any other health samples.

Local-First Data

  • Health summaries, workout snapshots, widget snapshots, appearance choices, unit preferences, Health source choices, card visibility, and app icon choices stay on this device.
  • Widgets read a cached snapshot from the shared app group. Widgets do not query HealthKit directly.
  • Your Body Pro status is mirrored into that same shared app group as a simple flag, so a widget can tell whether it is unlocked without contacting the store.
  • If you use the Apple Watch app, ohmybody sends a compact metrics snapshot to your paired watch through Apple WatchConnectivity so the watch app and complications can display recent values.
  • To let Siri, Shortcuts, and Spotlight answer questions about your metrics, ohmybody keeps a copy of today's metric values in a protected search index on your device, which stays encrypted until you unlock the device after a restart. Siri answers come from ohmybody's cached data rather than a live Apple Health query, need an unlocked device, and clearing the local cache removes that copy.

Network Access

  • ohmybody does not send Apple Health data to external analytics, advertising, tracking, or AI services.
  • Purchases are processed by Apple and managed through RevenueCat. RevenueCat receives purchase and receipt information, transaction history, an anonymous app user identifier it generates for this install, and basic device and system details. It uses them to tell ohmybody whether Body Pro is unlocked and to give the developer purchase and subscription figures, such as sales, trials, and renewals. ohmybody does not link this data to your identity or use it for tracking or advertising. No Apple Health data is sent to it.
  • When a GPS workout route is shown, Apple MapKit may load map imagery, and Apple geocoding may be used to turn the route midpoint into a city or region label.
  • Feedback email is optional. If you choose Feedback, your email app prepares a message with app version, device, system, locale, and time zone details so you can review it before sending.
  • Opening How to Use, Support, or Privacy links loads the documentation pages from this website.

Your Control

  • You can change ohmybody's Health permissions in the Health app or iOS Settings.
  • You can choose default Apple Health sources in ohmybody's Data settings, hide Health categories from ohmybody, clear local caches, and rebuild the cache from Apple Health.
  • Saving a workout share card asks for permission to add photos to your library, and ohmybody only adds images. Choosing a photo as a share background reads just the image you pick.
  • Export Body Radar Replay in Data settings writes a file of recent Body Radar inputs and results on your device. It leaves your device only if you choose to share it.
  • Manage on the Body Pro page opens the purchase management center, where you can review your Body Pro purchase or change or cancel a subscription. Restore on the same page brings back an earlier purchase.
  • Deleting ohmybody removes the app's local cache and settings from the device.
