TL;DR – The Short Version

We collect ZERO data. GTM Params Injector works entirely in your browser. No tracking, no analytics, no servers, no data collection. Period.

Introduction

GTM Params Injector (“the Extension”) is developed and maintained by Nexef Labs (“we,” “our,” or “us”). We are committed to protecting your privacy and ensuring transparency about our data practices.

This Privacy Policy explains how GTM Params Injector handles information when you use our Chrome extension.

Information We Collect

The Simple Answer: None

GTM Params Injector collects absolutely no personal data, usage data, or any other information from users.

We do not:

• Track your browsing activity
• Collect analytics or usage statistics
• Store any information on external servers
• Use cookies for tracking purposes
• Transmit any data outside your browser
• Monitor which websites you visit
• Record what parameters you inject
• Collect personally identifiable information
• Gather usage metrics or telemetry

How the Extension Works

GTM Params Injector operates entirely within your browser:

1. Local Storage Only
   The extension uses Chrome’s local storage API (chrome.storage.local) to save your preferences (like last selected platform). This data never leaves your device.
2. No External Servers
   The extension does not communicate with any external servers, APIs, or third-party services. All functionality happens locally in your browser.
3. On-Demand Activation
   The extension only activates when you:
   • Click the extension icon
   • Are actively using Google Tag Manager
   It remains completely inactive on all other websites.

Permissions Explained

The extension requests the following permissions. Here’s exactly why:

1. scripting Permission

Why we need it: To inject parameters into Google Tag Manager’s interface
What it does: Allows the extension to fill in parameter fields in GTM
Your privacy: Only works when you actively click “Inject” – never automatic

2. storage Permission

Why we need it: To remember your last selected platform
What it does: Saves preferences locally in your browser
Your privacy: Data never leaves your device – stored only on your computer

3. Host Permission: https://tagmanager.google.com/*

Why we need it: The extension only works on Google Tag Manager
What it does: Allows the extension to access GTM pages
Your privacy: Extension is completely inactive on all other websites

Local Data Storage

The extension stores only the following data locally in your browser:

This data:

• ✅ Stays on your device
• ✅ Never transmitted anywhere
• ✅ Can be cleared anytime by uninstalling the extension
• ✅ Is not accessible to us or anyone else

Third-Party Services

We use NO third-party services.

The extension does not integrate with:

• Analytics platforms (Google Analytics, etc.)

Your Data Rights

Because we don’t collect any data, there’s nothing for you to:

• Request access to
