Anyone using Seline Analytics? How's privacy handling compared to GA4?

Been looking at alternatives to GA4 for a client project where privacy is a real concern. Seline Analytics keeps coming up—specifically the privacy-first angle. Has anyone here actually deployed it? I'm curious about the AI insights feature and whether the dashboards give you enough depth for conversion tracking without feeling stripped down. Also wondering how the setup compares to GA4 in terms of implementation time.
