Data Share Guard (DSG) is a free Chrome browser extension that enhances users' understanding of online privacy by analyzing the data collection practices of websites. It provides a real-time privacy score, presented in a color-coded format, which indicates the level of data collection and sharing on each site. Users can click on the privacy score for detailed insights into specific risks associated with geolocation tracking, browsing history, and third-party data sharing.

This extension is designed for transparency rather than protection, meaning it does not block or prevent data collection but informs users about potential risks. While it offers educational insights and is easy to use, it does not guarantee detection of all data practices due to the evolving nature of tracking technologies. Therefore, users should remain cautious and consult privacy policies for comprehensive details.
