Cookies and analytics on kefilex.com.

What we track on this site.

• ·Pages you visit and how long you stay.
• ·Which links and buttons you click — including the waitlist and register-interest forms.
• ·Country (approximate, from IP — not stored alongside your visits once aggregated).
• ·UTM parameters on inbound links (so we know which channel sent you).
• ·Session recordings of mouse movement, scrolling, clicks and page transitions — with form-input contents masked at capture. We use these to spot where the page is friction-y (e.g. people hovering over a confusing label or rage-clicking a non-button). We never see what you type.
• ·Heatmaps of where people click and how far they scroll on each page. Built from the click events above — no extra data captured.
• ·Web vitals (load times, layout shift, responsiveness) so we can fix the page when it's slow for you.
• ·When you submit a form, the contents of that form (name, firm, email, etc.) are stored — that's the whole point of the form.

What we don't track.

• ·What you type into form fields. Inputs are masked at the moment of capture — they never reach PostHog. Only the submitted value is stored, and only once you press the submit button.
• ·Cross-site browsing through advertising networks.
• ·Anything we share with third-party advertisers — we don't use any.
• ·Anything until you tap Allow analytics on the banner. The default is off.

Tools we use.

• ·PostHog for analytics, session recordings (with masked inputs), and heatmaps. EU-hosted, GDPR-compliant. Drops a cookie to remember your consent and a session ID.
  Requests route through kefilex.com/ingest so that browser-level ad blockers don't drop them — the data still goes to PostHog EU under the same consent gate.
• ·Netlify for hosting and form submissions. Form submissions are stored on Netlify and forwarded to hello@kefilex.com.
• ·Fontshare and Google Fonts for typefaces. Fonts are loaded from their CDNs.
