Fitbit vs Redmi Watch 5 — Privacy Comparison (Google-Owned vs China-Mfg with EU Servers)

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

TL;DR. Fitbit was acquired by Google in 2021; data flows are now governed by Google's privacy policies. Fitbit has not published a third-party forensic audit. Redmi Watch 5 (€60-90) is audited by Ainode at Tier B (32/100), with traffic captured to Xiaomi's EU-region servers (adequate GDPR jurisdiction). Both are mass-market — but only Redmi Watch 5 has a public PCAP record of where the data actually goes.
