Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\Line\Telemetry\line-telemetry.exe
Warning
Telemetry can spawn multiple background tasks
Line runs several background workers for telemetry, crash reports, and updates
Can I Disable?
✔ YES
In LINE app: Settings → Privacy → Telemetry, disable data sharing; you may also exit LINE and stop the service
What is line-telemetry.exe?
line-telemetry.exe is the LINE messaging application's telemetry component. It runs as a background service to collect anonymized usage data, crash reports, and performance metrics to help LINE improve stability and features. It may start with Windows or when LINE launches and can influence network activity and CPU usage during data transfers.
This process operates as a small multi-threaded background agent that batches and securely transmits diagnostic data to LINE servers. It primarily supports diagnostics and product improvements and usually does not alter user chats or core LINE functionality.
Quick Fact: Line telemetry was designed to run with minimal impact, but excessive network activity can occur during update checks or crash reporting.
Types of Line Telemetry Processes
- Telemetry Processor: Collects anonymized usage data for product improvements
- Crash Reporter: Gathers and uploads crash dumps for diagnostics
- Update Checker: Checks for LINE desktop updates and reports success/failures
- Network Communicator: Sends data securely to LINE servers
- Background Worker: Performs maintenance tasks and data aggregation
- Diagnostic Handler: Manages diagnostic event logging and batching
Is line-telemetry.exe Safe?
Yes, line-telemetry.exe is safe when it's the legitimate file from LINE and located in the official installation path.
Is line-telemetry.exe a Virus or Malware?
The real line-telemetry.exe is NOT a virus. However, malware can mimic names; verify using digital signatures and exact location.
How to Tell if line-telemetry.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Line\Telemetry\line-telemetry.exe or C:\Program Files (x86)\Line\Telemetry\line-telemetry.exe. Any line-telemetry.exe elsewhere is suspicious.
- Digital Signature:: Right-click the executable in its folder → Properties → Digital Signatures. Should show "LINE Corporation".
- Resource Usage:: Normal usage is 0.5-4% CPU and 20-120 MB memory. Persistently higher usage or a missing signature is suspicious.
- Behavior:: Line telemetry should run when LINE is installed or active. If it runs without LINE, investigate further for malware.
Red Flags: If line-telemetry.exe is located in unusual folders (like Temp or AppData), runs when LINE isn't open, lacks a digital signature, or uses excessive resources constantly, run a full antivirus scan. Look for similarly named files like "line-telemetry_x64.exe" from untrusted sources.
Why Is line-telemetry.exe Running on My PC?
line-telemetry.exe runs to collect and send diagnostic data, crash reports, and performance metrics to LINE servers, either when LINE is active or when background data collection is enabled.
Reasons it's running:
- Active LINE Use: LINE is running or a chat session is active; telemetry collects usage metrics to improve features.
- Background Data Sync: Telemetry components run to aggregate usage statistics and crash logs in the background.
- Startup Program: LINE or its telemetry services are configured to start with Windows, causing immediate background activity.
- Update and Diagnostics: Telemetry may run during update checks or diagnostics when LINE is installed or updated.
- Background/Crash Reporting: Telemetry handles crash dumps and event logs to LINE servers to assist developers.
Can I Disable or Remove line-telemetry.exe?
Yes, you can disable line-telemetry.exe. It's safe to limit data collection or stop telemetry if you prefer more privacy, and you can uninstall LINE if you no longer use it.
How to Stop line-telemetry.exe
- End Individual Telemetry Tasks: Open Task Manager (Ctrl+Shift+Esc), locate line-telemetry.exe, and End Task as needed
- Close LINE: Exit LINE entirely to stop telemetry activity
- Prevent Startup: Task Manager (Ctrl+Shift+Esc) → Startup tab → Disable LINE or Telemetry-related entries
- Disable Telemetry in LINE: LINE Settings → Privacy → Telemetry → Turn Off data collection
- Stop Background Apps: LINE Settings → Privacy/Advanced → Disable "Continue running background apps when LINE is closed"
How to Uninstall LINE
- ✔ Windows Settings → Apps → Apps & Features → LINE → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → LINE → Uninstall
- ✔ Consider alternative messaging apps if you plan to switch
Common Problems: High Telemetry Data or Resource Usage
If line-telemetry.exe is consuming excessive resources or network bandwidth:
Common Causes & Solutions
- Telemetry enabled during heavy LINE usage: Limit telemetry in LINE Settings or temporarily disable during peak usage
- Frequent update checks: Disable automatic update checks for telemetry in LINE settings or schedule updates manually
- Excessive crash reporting after a recent crash: If crashes are frequent, collect logs and update LINE. Consider disabling crash reporting if privacy is a concern
- Outdated LINE version: Update LINE to the latest version via official site or app store
- Background data synchronization: Reduce data sync frequency in LINE Settings → Privacy → Telemetry
- Security software interference: Ensure antivirus/firewall isn't blocking LINE telemetry, which can cause retries and higher CPU usage
Quick Fixes:
1. Quick Fixes:
2. 1. Open Task Manager (Ctrl+Shift+Esc) and identify line-telemetry.exe
3. End the process for problematic telemetry activity
4. Update LINE to the latest version
5. Disable Telemetry in LINE Settings
6. Check Windows Startup and disable LINE if needed
