04. Frequently Asked Questions (FAQ)
This chapter summarizes the most common issues and solutions for GarSync 2.0.
1. Accounts & Authorization
Q: Why are there two Garmin icons? Which one should I choose?
A: Garmin operates two isolated server regions: China and Global.
- If you registered using a Chinese mobile number, you belong to Garmin China.
- If you registered via email on garmin.com, you belong to Garmin Global.
- Note: Data is not shared between these regions. Choosing the wrong icon will result in successful logins but no data visibility.
Q: My Strava authorization expires after a few hours. Why?
A: You likely didn't check the "Access your data at any time" box during the OAuth process.
- Solution: Remove the Strava account in GarSync and add it again. Ensure you check all permission boxes on the redirected web page.
2. Syncing Data
Q: Will syncing cause duplicate activities?
A: No. GarSync employs an intelligent deduplication algorithm. It uses the original timestamp (Start Time) as a unique identifier (GUID). Even if you cross-sync from multiple platforms, the system detects the same activity and skips redundant uploads.
Q: How do I sync old activities?
A: When creating a sync task, check the "Sync History" option. You can also perform a "Full Refresh" in the Account Management page for a specific account to force-scan all historical records.
3. Connectivity & Compatibility
Q: Why do I get a "500 Internal Server Error"?
A: This usually indicates temporary instability on the target platform's server (e.g., Keep or Codoon). Try tapping "Retry" on the task card. If it persists, the platform's API might have changed — please wait for an app update.
Q: I can't connect to my NAS. What should I check?
A: Please ensure:
- Your phone is on the same network as the NAS, or you have configured external access (DDNS/VPN).
- SMB v2/v3 is enabled on your NAS (GarSync does not support the insecure SMB v1).
- Your firewall allows traffic on port 445.
4. Privacy & Security
Q: Does GarSync store my activity data?
A: GarSync follows a "Data Sovereignty" philosophy.
- Your raw files and GPS tracks are stored only on your local device and your private NAS.
- Our servers only store minimal metadata (time, type) to keep sync states consistent across your devices.
- For AI coaching, data is transmitted anonymously via encryption and is not used for model training.
