What is turtl.exe?
turtl.exe is the Windows executable for the Turtl desktop client, a privacy-focused note-taking application. It launches the app and coordinates the main UI, data encryption, and synchronization tasks across windows.
Turtl uses a multi-process Electron-based model where the main process manages the app lifecycle and separate renderer processes handle each window's content, enabling isolation and security.
Quick Fact: Turtl emphasizes privacy by encrypting notes locally and during sync, helping protect user data across devices.
Types of Turtl Processes
- Main Process: Core app lifecycle and global state management (1 instance)
- Renderer Process: Each Turtl window or pane renders its content in a separate process
- Sync/Background Process: Background tasks handling encryption and cloud sync
- Notification/Tray Task: System tray icons and in-app notifications
- Update/Installer Process: Auto-update checks and installation tasks
Is turtl.exe Safe?

Is turtl.exe a Virus or Malware?
The real turtl.exe is NOT a virus. However, malware may masquerade with similar names. Verify the file path and signature.
How to Tell if turtl.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\turtl\turtl.exe or C:\Users\\AppData\Local\turtl\turtl.exe. Any other path is suspicious.
- Digital Signature: Right-click turtl.exe → Properties → Digital Signatures. Should show "Turtl Project" as the signer.
- Resource Usage: Normal usage is 1-8% CPU per window, 60-180 MB total memory. Abnormal spikes when idle are suspicious.
- Behavior: Turtl should only run when you open the app. Unsolicited background activity or multiple silent processes may indicate malware.
Red Flags: If turtl.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when the app isn't open, has no valid digital signature, or uses constant resources, scan your system with antivirus software. Look for similarly-named files like "turtl.exe" in untrusted sources.
