Розробка self-hosted платформи комплексного аналізу взаємодії користувачів з веб-ресурсами з дотриманням вимог захисту персональних даних

Abstract

This work presents LiteMetrics, a self-hosted cookie-free web analytics platform that follows an aggregate-first principle: all data is stored as counters without association to individual visitors. No IP addresses, User-Agent strings, or cookies are persisted, eliminating the need for consent banners and ensuring GDPR/CCPA compliance. The system is built with Go (Gin), React (TypeScript, Vite), and PostgreSQL, containerized via Docker. It includes 12 modules: a JS tracker, real-time dashboard, visit statistics, click heatmaps, scroll maps, page-level recordings (rrweb), conversion funnels, a feedback widget, multi-site support, rolebased access control, a REST API, and PDF/CSV export
