Offen Fair Web Analytics is a privacy-focused, self-hosted web analytics platform that emphasizes user consent and data ownership. The system employs a multi-service architecture consisting of a Go-based backend server for API and data persistence, a Node.js vault service for client-side encryption and key management, a Node.js tracking script for event collection, and a Node.js auditorium interface for users to view their analytics data. All services are orchestrated via Docker Compose, with Nginx acting as a reverse proxy. The platform ensures privacy through end-to-end encryption of analytics data in the browser before transmission to the server, preventing even the server operator from accessing raw data without the user's key. It implements granular consent management, data retention policies (default 6 months), and allows users to review, export, or delete their data via the auditorium. The system supports multiple databases (SQLite, MySQL, PostgreSQL) and provides internationalization for over six languages.
