🕵️‍♂️ Do Not Track Polyfill

A simple GitHub Action that conditionally disables telemetry by setting opt-out environment variables for several popular vendors. It ensures your workflow respects privacy-focused settings by preemptively opting out of analytics, usage reporting, and tracking features — if the relevant tools support them.

✨ Features

Adds common telemetry-related environment variables (e.g., ASTRO_TELEMETRY_DISABLED, etc.)
Helps opt out of analytics, error reporting, and tracking

🚀 Usage

Add the action to your workflow before any steps that might invoke telemetry aware tools
