Privacy Policy

Last updated: February 21, 2026

Cloud Env Marker ("the Extension") is a browser extension that color-codes cloud console headers by environment. This privacy policy explains what data is collected and how it is used.

Data Collection

Data Stored Locally

The following data is stored in your browser's local storage (chrome.storage.local) and never leaves your device:

• Environment rules — Cloud provider, pattern, color, and label configurations you create
• License state — Whether a Pro license is active (boolean flag)
• License key — Your Polar license key (if activated)
• Activation ID — Your Polar activation identifier (if activated)

Anonymous Analytics (Google Analytics 4)

The Extension sends anonymous usage events via the GA4 Measurement Protocol:

• extension_installed — sent once on first install
• extension_updated — sent on extension update
• cloud_detected — sent when a supported cloud console is visited (cloud provider name only; no URL, account ID, or project name is included)
• weekly_active — sent once per week to measure active usage

License Validation (Polar)

When a license key is entered, the Extension communicates with the Polar API (api.polar.sh) to:

• Validate the license key status
• Activate or deactivate the license

Only the license key and organization ID are sent. No browsing data or personal information is transmitted.

Data NOT Collected

The Extension does not collect:

• Browsing history or visited URLs
• Cloud account IDs, project names, or subscription details
• Personal information (name, email, etc.)
• Cookies or tracking identifiers from cloud consoles
• Screenshots or page content

Content Script Behavior

The Extension injects content scripts into the following domains solely to add a colored header bar:

• console.aws.amazon.com — AWS Console
• console.cloud.google.com — GCP Console
• portal.azure.com — Azure Portal

Content scripts read only the minimal DOM elements needed to identify the current account/project/subscription for rule matching. This information is processed locally and is never transmitted externally.

Data Retention

• Local storage data persists until you uninstall the Extension or clear browser data
• Analytics events are retained according to Google Analytics' standard retention policy
• License data is managed by Polar according to their privacy policy
