Privacy Policy
The short version: no third-party analytics, no advertising cookies, no data selling. Details below.
What we log automatically
Like any web server, ours (nginx) writes a standard access line per request: IP address, timestamp, requested URL, browser user-agent and referrer. We use this for traffic counts, debugging and filtering bots.
We also run our own first-party event tracking to understand the funnel: page views, scroll depth, whether the pricing section was seen, whether a quote button was clicked, whether the quote calculator was submitted. These events stay in our own server logs.
What we don't do
- No Google Analytics, Meta Pixel or any third-party analytics or ad-tracking script;
- No advertising cookies, no cross-site tracking, no selling or sharing visitor data;
- No sign-up required, so we hold no name or phone data unless you contact us directly by email, WeChat or Telegram.
Local storage in your browser
- kf-dark — your light/dark theme choice;
- kf-ab-hero — which A/B variant you were assigned;
- kf-notice-1 — that you dismissed the privacy notice.
None of these contain personal data. Clearing browser data removes them.
How we use the data
To answer three questions: how many people visit, where they drop off, and which headline makes more people ask for a quote. We look at aggregates only — we don't build per-visitor profiles and we never use this data to contact you.
Retention
Server access logs rotate with system logs, typically under 30 days. Project emails you send us are kept for the duration of the engagement.
Your rights
Email hello@kaifaai.app if you want access logs or correspondence related to you deleted; we handle it within 7 business days. Where GDPR or similar regimes apply, you keep the rights of access, rectification, erasure and restriction of processing.
