Diagnostic logs

Purpose: Diagnostic logs help technicians troubleshoot connection failures, node switching issues, authentication, or device binding. They do not replace the data categories defined in our Privacy Policy.

What to include: Export a file from the app’s diagnostic export feature when available. It typically includes app version, platform, selected node, connection stage, API request status, structured error codes, native VPN status, probe results, recent client events, and redacted configuration summaries.

Do not include: Full session tokens, Authorization headers, plaintext passwords, private keys, WireGuard client private keys, communication payloads, or browsing content.

How to send: Attach the exported file to your email, or use a secure channel if support directs you to one. Do not paste full logs in public forums.

Retention: Diagnostic logs are kept only as long as needed for troubleshooting. See our Privacy Policy for details.
