Health Data Security: A Buyer's Checklist
Before any device touches your health data, run this checklist. The security features that separate trustworthy products from risky ones.
Health hardware collects some of your most sensitive data. Before you trust any device, run this security checklist to separate genuine protection from marketing.
Where and how data is processed
Prefer on-device-first processing that minimises what leaves your home. Ask whether raw data is uploaded and, if so, how it is encrypted in transit and at rest.

Revocable

Ownership and control
You should be able to export and delete your data, and every share should be explicit and revocable. Data minimisation should be the default, not an option.
- On-device-first processing
- Encryption in transit and at rest
- Export and delete controls
- Explicit, revocable consent
“Privacy is not a constraint on the product — it is the product.”
Transparency
Clear, plain-language policies are themselves a security signal. Vagueness is a red flag.
