Short version
- Used for — reading heart rate and calories during workouts, and saving completed activities back to Health.
- Stored where — entirely on your iPhone, inside Apple Health's encrypted store. We never see it.
- Never sent to our servers — Motum has no server endpoint for health data. It physically cannot leave your device.
- You can revoke — anytime in Settings → Health → Data Access & Devices → Motum.
What Motum reads and writes
When you grant Apple Health access, iOS shows you a per-category list with toggles. Here's exactly what Motum asks for and what it does with each:
ReadFrom Health
- Heart rate — shown live during workouts and recorded with every activity.
- Resting heart rate — used as a baseline for fitness calculations.
- Active calories — displayed in your activity stats.
- Step count — shown on the dashboard for today.
- Walking + running distance — used when computing your daily totals.
- Cycling distance — same, for rides.
- Workouts — to know which sessions Health already has.
- Date of birth — used to auto-fill your age for calorie estimation. Optional — you can also type it in manually.
WriteTo Health
- Completed workouts — every activity you record in Motum is saved to Apple Health as a workout with type (running, cycling, walking) and outdoor location.
- Active calories — the calorie estimate for each workout.
- Walking + running distance — total distance for run/walk activities.
- Cycling distance — total distance for rides.
You can grant any subset of these. iOS shows toggles for each category when you tap "Enable Apple Health" — uncheck anything you don't want Motum to read or write, and it'll work around the missing data.
Why your health data stays on your device
Apple Health is an end-to-end encrypted store managed by iOS. When Motum reads your heart rate, the data is handed to the app's process by Apple Health on your device — it never travels through a server we control. When Motum writes a workout back to Health, it goes from Motum's process directly into Apple Health on the same device. Nothing transits our infrastructure.
This isn't a policy promise — it's an architectural fact. Motum has no server endpoint that accepts heart rate, calories, or workout data. Even if we wanted to collect it, we'd have to write that code first.
If you use iCloud to sync Apple Health across your devices (iPhone, iPad, Apple Watch), that sync is between Apple's servers and your devices — Motum is not part of that pipe.
What "iOS doesn't tell us" means
One detail worth knowing: Apple HealthKit doesn't tell apps which individual categories you granted or denied. Motum only knows that you dismissed the permission sheet — not whether you allowed heart rate but blocked calories. If you grant some categories but not others, the app will simply show empty fields for the ones you blocked, and behave normally for the rest.
This is a privacy feature in iOS, not a Motum limitation. Apple wanted to prevent apps from probing what you allow and don't allow.
If you denied permission
Motum still records GPS workouts normally, but without heart rate, calorie data, or workouts saved back to Apple Health. You can grant access later from the Apple Health app:
Health app → Sharing tab → Apps → Motum → Turn on the categories you want to share
How to revoke access
You can turn off Apple Health access for Motum entirely, or revoke individual categories:
Settings → Apps → Health → Data Access & Devices → Motum → Turn Off All
Or from inside the Health app itself, navigate to Sharing → Apps → Motum.
Workouts Motum has already written to Apple Health remain in Health — you'd need to delete those individually from inside the Health app if you want them gone.
