Data collection
n8n collects some anonymous data from self-hosted n8n installations. Use the instructions below to opt out of data telemetry collection.
Collected data
Refer to Privacy | Data collection in self-hosted n8n for details on the data n8n collects.
How collection works
Your n8n instance sends most data to n8n as the events that generate it occur. Workflow execution counts and an instance pulse are sent periodically (every 6 hours). These data types mostly fall into n8n telemetry collection.
Opting out of data collection
n8n enables telemetry collection by default. To disable it, configure the following environment variables.
Opt out of telemetry events
To opt out of telemetry events, set the N8N_DIAGNOSTICS_ENABLED environment variable to false, for example:
export N8N_DIAGNOSTICS_ENABLED=false
Opt out of checking for new versions of n8n
To opt out of checking for new versions of n8n, set the N8N_VERSION_NOTIFICATIONS_ENABLED environment variable to false, for example:
export N8N_VERSION_NOTIFICATIONS_ENABLED=false
Disable all connection to n8n servers
If you want to fully prevent all communication with n8n's servers, refer to Isolate n8n.
