Privacy & measurement
BioWadi is built for families. We want to learn what helps — without collecting what we do not need.
What we measure
Server page views; first-party product events (CTA clicks, article open, read depth, poll votes, newsletter signup, language/theme switch); basic campaign params (utm_*) when you arrive from a shared link.
What we do not collect
Children’s names, ages, schools, or free-form chat. Email is stored only if you subscribe — separate from browsing metrics.
How a visitor is identified
An anonymous id in localStorage plus a daily hash of IP (not the full address). There is no child user account.
Third-party tools (Google Analytics)
In production we intentionally run Google Analytics 4 (G-2JK1SQ0BN9) alongside our first-party event store — so we can see acquisition channels and return visits. IP is anonymized in GA. No child accounts; a parent should supervise use.
Who this is for
Curious kids with parents/adults. A grown-up should join the first visit.
