Manual method
Preserve Fitbit history held in your Google Health account using Google Takeout.
- Sign in to Google Takeout with the Google account holding the wearable history.
- Select the Google Health category corresponding to your Fitbit/Google Health data and review included data.
- Request a one-time downloadable archive, then save all completed parts.
- Extract a working copy and inspect measurements and workout coverage.
Coverage and limitations: Google now documents the Fitbit app as Google Health; old screenshots may show a different label. Only history retained in the accessible account can be exported. A Takeout archive does not guarantee all another platform’s import formats or proprietary scores.
Size and time to allow
Illustrative small / central / large case: 0.05 / 1 / 10 GB (decimal GB). These are planning assumptions, not a measured average per person. 1 GB is a planning example for years of frequent wearable measurements and some workout routes; short histories can be much smaller.
Preparation: Takeout preparation can take minutes to days. Keep the account accessible until the archive is downloaded and checked.
For the central 1 GB example, network transfer alone is approximately:
| Connection | Estimated transfer |
|---|---|
| 10 Mbps | 19.0 minutes |
| 50 Mbps | 3.8 minutes |
| 100 Mbps | 1.9 minutes |
Assumes 70% sustained use of the stated connection. Provider throttling, many small files, retries, local extraction and copying add time. For online backup use your upload speed. These are not estimates of the provider’s preparation queue. See calculation and large-file advice.
Store and verify the archive
An encrypted external drive is a practical main archive; a USB key can carry a copy if it has sufficient free space. Keep an additional encrypted copy on another device or private online backup, outside the source account’s sync folder. For health records, restrict access and avoid shared-family/public-link destinations; keep encryption recovery information separately.
Create fitbit/YYYY-MM-DD/originals/, preserve the untouched download, and extract a separate working copy when needed. Allow extra free space for archive plus extraction; compressed text can expand far beyond twice its size. Record account/scope, export date, date coverage and missing items in a local README without passwords.
Check old/recent sleep, activity and heart-rate records plus available workouts; preserve original units and timestamp fields. Reopen a sample from the second copy before deleting or replacing any source. Storage choices and verification.
