Use the instructions below to opt out of data telemetry collection. ## Collected data Refer to [Privacy | Data collection in self-hosted n8n](/privacy-security/privacy.md#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: ```bash 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: ```bash 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](/hosting/configuration/configuration-examples/isolation.md). ## Related resources Refer to [Deployment environment variables](/hosting/configuration/environment-variables/deployment.md) for more information on these environment variables. Refer to [Configuration](/hosting/configuration/configuration-methods.md) for more information on setting environment variables.
