Matomo

Matomo is an open source web analytics program for analyzing activity on websites. It enables people and organizations to obtain web analytics while maintaining control over their data, with data protection and customer privacy treated as central concerns. Released under the GPL-3.0 license, it is intended for anyone who needs to understand website activity without relying on Google Analytics, particularly when control of analytics data and respect for customer privacy are priorities. Matomo provides an alternative to the paid product Google Analytics. However, it should not be assumed to match Google Analytics feature for feature. The available information describes Matomo as a privacy-centered alternative rather than an exact duplicate of Google Analytics, so users should expect differences between the two services.
