Umami is a web analytics platform. When comparing alternatives, first state which decisions your analytics must support; a dashboard with more charts may not answer them better.
Instrument a test site with pageviews and three meaningful events, such as sign-up start, completed sign-up, and a failed action. Compare event counts with server-side truth over several days. Check campaign parameters, referrers, bot traffic, time-zone boundaries, retention, export, and access control. Review whether custom event properties contain personal data you did not intend to collect.
Umami's event documentation describes named events and properties. Before switching, verify the data model and historical-data export. Privacy claims depend on your configuration and consent obligations, not merely on using a privacy-oriented tool.
