Data egress from self-hosted instances

Last updated:

What data does PostHog collect from self-hosted instances?

In order to understand usage and build better products, PostHog instances routinely send usage reports to our servers. In addition, this data helps us troubleshoot when we provide support. These reports do not contain any raw person, event, or group data — ie no identifiable or unique information from your users, only anonymized, aggregated data.

What if I cannot allow data egress or need to run in an air gapped environment?

You can run the open-source version of PostHog in an air-gapped environment, though it does require internet access to use the installation script.

What data is sent in the usage report?

The following is an example status report that would be sent from your instance to PostHog's servers.
