How to back up Galaxy Watch data on PC without Samsung Cloud

You want a copy of your Galaxy Watch data on your computer. You don't trust Samsung cloud alone, or you're switching ecosystems, or you simply need to analyze your HR in Excel. There are four real options, and none is 'one click'. We explain what works, what's clunky, and when each is worth it.

Option 1: Samsung Health's internal export

Samsung Health (Android) has a built-in export function generating a package of files with all your raw data. It's not promoted in tutorials, but it's been there for years.

1. Open Samsung Health on the phone.
2. Tap ☰ menu top-left → Settings.
3. Scroll to 'Download personal data'.
4. Confirm with Samsung Account password.
5. Wait (can take 1–24 hours if you have years of data). You'll receive a ZIP via email.

The package contains CSV files for each data type (steps_*.csv, heart_rate_*.csv, sleep_*.csv, exercise_*.csv, etc.) plus binary files for high-frequency data like continuous HR during workouts. It's complete but verbose. To analyze in Excel/Numbers just import the CSVs; for more sophisticated visualizations use Python pandas or R.

Option 2: GDPR right-of-access request

If you're in the EU, you can formally write to Samsung asking for all data collected about you (GDPR art. 15 and 20). For health data the contact is privacy.eu@samsung.com (or the dedicated form at privacy.samsung.com/en/privacy-rights). They have 30 days to respond, free of charge. The dataset you receive is typically broader than the internal export (includes metadata, access logs, account info).

Option 3: read via Health Connect on a third-party app

Since 2024 Samsung Health writes to Health Connect, Android's official API. You can install a third-party app reading via Health Connect and exposing data in the format you want: web dashboard, JSON files, sync with other ecosystems. It's the most automated way.

• •For web dashboard: FitMesh Sync reads from Health Connect and shows everything on a PC-accessible web app.
• •For technical export: apps like Health Connect Toolbox (open source) produce manual JSON dumps.
• •For advanced analytics: apps like Welltory or Bearable read HC and provide coaching/journaling.

Caveat: this path works for data Samsung Health writes to Health Connect — so steps, HR, sleep (total and basic stages), calories, distance, workouts. For Samsung-proprietary data like Body Composition or continuous Stress Score you'll always need Samsung Health's internal export.

Option 4: ADB backup (advanced)

For the more technical: Samsung Health data lives on the phone in a SQLite database. With a USB cable, ADB enabled in developer options, and a tool like adb backup or root you can extract the file and read it directly. Not recommended if you don't know what 'developer options' means — easy to break things and risks violating ToS.
