Google Health Export Overview
Google Health data exports are not yet available, but data collection is available for MyDataHelps participants. This article is being published ahead of Google Health data export availability and is subject to change.
As a reminder, Google is deprecating the Fitbit API on September 30th, 2026. After this date, Fitbit data will only be available through Google Health. Please refer to the Migrating Fitbit to Google Health article for additional information.
Google Health enables multi-stream data collection using the Google Health app on iOS and Android devices. This includes users of Fitbit devices, as well as a range of other wearables, health, and fitness apps.
To enable Google Health sensor data collection, navigate to the Sensor & EHR section of your project and enable it. For more on migrating from Fitbit data collection, see the migration guide.
The following Google Health data exports are currently available.
- Daily Data: A daily data summary per participant per day, e.g. total steps, heart rate zones, heart rate variability, and nutrition.
- Exercise: Individual fitness sessions (runs, workouts, etc.), including splits and start/stop events.
- Sleep: Sleep session data, including sleep stages and out-of-bed segments.
- Sleep Respiratory Rate: Breathing rate derived from a sleep session.
- Time Series: Interval and sample-based readings that aren't part of Daily Data, such as blood glucose and step counts.
Deletions
When a participant deletes Google Health data, most exports write a companion _Deleted file identifying the participant and date range that was removed, in addition to omitting the deleted data from the regular export files. See Google Health Deleted Export Format for details on how these files are structured and how to apply them. Daily Data does not have a companion deleted file—deletions are represented as updated daily records which overwrite the deleted record(s).
