What we track, what we don't
GDPR-aligned editorial position. Health data is sensitive — we apply privacy-by-default across every feature on the site. Here is the inventory.
What we track
Affiliate click events
Why: Attribute conversions to source pages; pay editorial team
Anonymous click ID, source-path, position, country, region, salted session hash. No PII.
Web Vitals (LCP / CLS / INP)
Why: Detect performance regressions
Sampled at 50%. Metric name + value + path. No PII.
Search queries
Why: Find content gaps (zero-result queries flag missing pages)
Query string only, no user identifier. Aggregated count + zero-result rate.
404 hits
Why: Identify broken-link patterns to fix
Path only. No user identifier.
What we don't track
- Your weight, A1C, dose, or any health metric (those stay 100% on your device)
- Reading time / time-on-page per article
- Cross-site behavior or third-party advertising trackers
- Browser fingerprinting
- Device IMEI / advertising IDs
- Real names or email addresses tied to behavior (newsletter signups are opt-in and stored separately)
