Insta Unfollow Checker ("the Extension") is a Chrome browser extension that helps you identify Instagram users who don't follow you back. This privacy policy explains what data we collect, how it is used, and how it is stored.

* All data listed above is processed entirely within your browser and is never transmitted to any external server. It is used only for local comparison and is not stored permanently unless you choose to save analysis results.
All data is stored locally on your device. We do not operate any backend servers and do not store any of your data externally.

We do not send data to any other third-party services, analytics platforms, or advertising networks.
We do not sell, trade, or share your data with any third parties. Your Instagram data and Google email remain on your local device.
