Why does Lago need data?

We decided to open-source the billing API we would have dreamt to use. As a consequence of building a self hosted product, we are not able to easily collect any usage metrics or insights to help us build a better product. This analytic help us understand crucial behaviors and ship better quality to serve your needs.

We decided to track, by default, so basic behaviors and metrics that are important to understand the usage of Lago. We have built a minimum required tracking plan to minimize the security impact of collecting those events. All the metrics collected are listed in a further section. We make this as transparent as possible, and we don’t track financial information (amounts of invoices, for instance).

The metrics are collected through the server side Ruby source from Segment.com.

Lago will not collect any financial information about your customers or your invoices.

​
Opting out

As detailed previously, we ask you to keep as much as possible those tracked metrics, unless you have a specific reason to opt out. Keeping the metrics enabled is the easiest way for Lago to get feedback based on product usage.

In the case you need to remove it, we’ve created a very easy process to opt out. In the environment variables, by passing the field LAGO_DISABLE_SEGMENT to true, you prevent the entire tracking logic to run in your application.
