Exactly what data Nutrola reads from and writes to Apple Health

When you connect Apple Health on iOS, Nutrola asks to read data Apple Health already has (steps, weight, energy, workouts, sleep, and more) and to write data Nutrola creates (your weight, body fat, water, dietary calories, macros, and workouts). You choose category by category in Apple's permission sheet, and can change any of it later.

What Nutrola asks to read from Apple Health

Nutrola requests read access to these categories so it can pull in activity and body data instead of making you enter it twice:

• Steps
• Weight
• Body fat percentage
• Height
• Date of birth
• Biological sex
• Active energy burned
• Basal (resting) energy burned
• Walking and running distance
• Flights climbed
• Workouts
• Water
• Dietary energy (calories consumed)
• Protein
• Carbohydrates
• Total fat
• Sleep

Requesting a category is not a promise that every one drives a visible feature in the app. Some scopes (for example sleep, height, basal energy, distance, and flights climbed) are requested so the data is available, but you may not see a dedicated screen for each one. Steps, active energy, weight, and workouts are the ones that most directly feed your daily numbers.

What Nutrola writes back to Apple Health

When you log things in Nutrola, it can write them back to Apple Health so your other apps stay in sync. The write categories are:

• Weight
• Body fat percentage
• Water
• Dietary energy (calories)
• Protein
• Carbohydrates
• Total fat
• Workouts

So a meal you log in Nutrola can appear in Apple Health as dietary energy plus protein, carbs, and fat, and a weigh-in or logged workout shows up there too. Water you log in Nutrola also writes to Apple Health on iOS.

You control each category yourself

When you tap Connect to Apple Health (in Settings under Health & Devices), iOS shows its own permission sheet with a separate toggle for every read and write category listed above. You decide what to turn on. If you leave some off, Nutrola simply works with less data.

One thing to know: after the permission sheet closes, Nutrola marks Apple Health as Connected locally. That status means the sheet was completed, not that you granted every category, so you can see "Connected" even if you declined some toggles. If something is not flowing the way you expect, that is usually a single category you left off.

How do I change what Nutrola can access later?

Apple, not Nutrola, controls these toggles after the first time. You change them in the iOS Settings app under Health, then your data access and devices list, then Nutrola. The exact wording and location of that screen vary by iOS version (Apple has placed it under Health > Data Access & Devices and elsewhere), so look for the Nutrola entry in the Health section of Settings. From there you can turn any read or write category on or off.

Notes

• Apple Health is iOS only. On Android, Nutrola syncs through Google Health Connect instead, which uses a different set of categories, and water does not sync to Health Connect. Health sync on Android (Google Health Connect) Which devices and platforms Nutrola supports
