Samsung Galaxy Ring vs SHR K3 — Smart Ring Privacy Comparison

Updated 2026-05-04 · Auditor: Tomás Maria Vaz de Noronha · Methodology: 3-pass forensic

TL;DR. Samsung Galaxy Ring is integrated into Samsung Health and the Galaxy ecosystem — privacy guarantees rely on Samsung's policies and a Galaxy phone for full functionality. SHR K3 (€129, Tier C audited) is ecosystem-agnostic, with public PCAP traffic captures showing exactly which servers it talks to. For users who don't own a Galaxy phone, or who want third-party audit verification independent of vendor self-attestation, SHR K3 is the verifiable option.
