Pirsch is a German, cookieless analytics tool with an open-source core. It identifies repeat sessions within a day using a salted hash that rotates and is not a device fingerprint, retaining no personal data. EU hosting and a processor posture make it a strong privacy choice for standard deployments without a consent banner.
