No, SeaLog only reads your scuba diving workouts from Apple Health. 🤿
It uses that information to bring supported dive data into your logbook, but SeaLog never writes, edits, or deletes anything in Apple Health.
So your Apple Health data stays exactly where it is. SeaLog simply reads what you choose to share.
Apple Health integration is available on iOS only.
Read-only means exactly that: your health data stays untouched.
