it, which can include identifiers from your setup. If you'd rather send nothing
at all, turn telemetry off using any of the options above.
## Error reports
When telemetry is enabled, **ktx** sends PostHog Error Tracking `$exception`
events for CLI and daemon exceptions. Error reports help group crashes and
handled failures into PostHog issues.
Error reports can include:
- Stack frames, including function names, local file paths, line numbers, and
SDK-provided source context.
- Error class names and raw error messages.
- Cause chains when the runtime exposes them.
- `source`, `handled`, and `fatal` diagnostic fields.
- Runtime version, OS, architecture, and CI fields.
- The hashed `projectId` when **ktx** knows the project.
Error reports never intentionally include:
- Secrets, credentials, API keys, tokens, cookies, signed URLs, or auth headers.
- Database URLs, connection strings, DSNs, raw argv, or raw environment values.
- SQL text, schema names, table names, or column names as explicit payload
properties.
- Customer row data.
- User prompt text or raw MCP arguments.
The same opt-out controls listed above disable error reports.

Telemetry is sent to PostHog, a third-party product-analytics service used by
