Samsung Galaxy Watch vs Redmi Watch 5 — Privacy Audit Comparison

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

TL;DR. Both watches integrate with their manufacturer ecosystems (Samsung Health vs Xiaomi MiFit). The Redmi Watch 5 has been independently audited by Ainode — Tier B (32/100), with verified data flows to Xiaomi's Frankfurt-region servers (adequate GDPR jurisdiction). Samsung Galaxy Watch 7 has no public independent PCAP audit. For buyers prioritising verified EU data residency, Redmi Watch 5 is the audit-backed option at a fraction of the price.
