About the Creator

Hi, I'm Sunil Yadav

I'm a software developer based in Gurugram with a passion for building tools that solve real-world problems. I created CommentCraft because I saw a need for a smarter, more efficient way to engage on professional platforms like LinkedIn.

My goal was to build a tool that was not only powerful but also respected user privacy above all else. That's why CommentCraft is completely free and designed so that I, the developer, never have access to any of your data. It's a tool built for the community, and I hope it helps you build meaningful connections.

Feel free to connect with me on LinkedIn!

Privacy Policy

Last Updated: August 19, 2025

Your privacy is the most important feature of CommentCraft. This policy outlines our commitment to protecting your data—by not collecting it in the first place.

The "Bring Your Own Key" (BYOK) Model

CommentCraft operates using a "Bring Your Own Key" model. This means you use your own personal Google Gemini API key to power the extension. This is fundamental to our privacy promise.

What We Do NOT Collect

CommentCraft does not collect, store, track, or transmit any of your personal information. This includes:

  • Your Google Gemini API Key
  • The content of any LinkedIn post
  • The comments you generate or write
  • Your LinkedIn account information
  • Your browsing history or any analytics data

How Your Data is Handled

1. API Key Storage: Your Google Gemini API key is stored exclusively in your browser's secure, synchronized storage (`chrome.storage.sync`). Only you have access to it, and it never leaves your browser to be sent to us.

2. API Communication: When you use a feature, the extension makes a direct, secure (HTTPS) call from your browser to the Google Gemini API. Your data is never routed through any servers owned or operated by CommentCraft.

Our Commitment

We are committed to maintaining this privacy-first approach. The extension will remain free, and its core architecture will always be designed to ensure that you are the sole controller of your data.
