-Standalone Go service for ProxmoxVE and ProxmoxVE data, cache, and telemetry.
+# Telemetry Service
+
+A standalone Go microservice that collects anonymous telemetry data from [ProxmoxVE](https://github.com/community-scripts/ProxmoxVE) and [ProxmoxVED](https://github.com/community-scripts/ProxmoxVED) script installations.
+
+## Overview
+
+This service acts as a telemetry ingestion layer between the bash installation scripts and a PocketBase backend. When users run scripts from the ProxmoxVE/ProxmoxVED repositories, optional anonymous usage data is sent here for aggregation and analysis.
+
+**What gets collected:**
+- Script name and installation status (success/failed)
+- Container/VM type and resource allocation (CPU, RAM, disk)
+- OS type and version
+- Proxmox VE version
+- Anonymous session ID (randomly generated UUID)
+
+**What is NOT collected:**
+- IP addresses (not logged, not stored)
+- Hostnames or domain names
+- User credentials or personal information
+- Hardware identifiers (MAC addresses, serial numbers)
+- Network configuration or internal IPs
+- Any data that could identify a person or system
+
+**What this enables:**
+- Understanding which scripts are most popular
+- Identifying scripts with high failure rates
+- Tracking resource allocation trends
+- Improving script quality based on real-world data
+
+## Features
+
+- **Telemetry Ingestion** - Receives and validates telemetry data from bash scripts
+- **PocketBase Integration** - Stores data in PocketBase collections
+- **Rate Limiting** - Configurable per-IP rate limiting to prevent abuse
+- **Caching** - In-memory or Redis-backed caching support
+- **Email Alerts** - SMTP-based alerts when failure rates exceed thresholds
+- **Dashboard** - Built-in HTML dashboard for telemetry visualization
+- **Migration Tool** - Migrate data from external sources to PocketBase
+

+
+## Privacy & Compliance
+
+This service is designed with privacy in mind and is **GDPR/DSGVO compliant**:
+
+- ✅ **No personal data** - Only anonymous technical metrics are collected
+- ✅ **No IP logging** - Request logging is disabled by default, IPs are never stored
+- ✅ **Transparent** - All collected fields are documented and the code is open source
+- ✅ **No tracking** - Session IDs are randomly generated and cannot be linked to users
+- ✅ **No third parties** - Data is only stored in our self-hosted PocketBase instance
