Client Hints and User Privacy: What You Need to Know

Client Hints is a browser feature that allows websites to gather information about a users device in order to serve customized content.

In this article, we will explore the impact of Client Hints on user privacy and offer insights into how it can be used responsibly.

What are Client Hints and How Do They Work?

These headers are sent by the browser to the server when a user requests a webpage, allowing the server to optimize content delivery based on the users device characteristics.
