My website and blog use Google Analytics to count visitors and understand their behaviour. For example, it gives me an idea of how people found my site and how often my products are downloaded. This involves creating cookies on your device, so that you get recognised as the same person across page views and visits, and aren’t counted as multiple people.
They’re not the kind of cookies that can be used to track your activity across the web. For example, they won’t affect what ads Google will show you.
Still, if you’d rather not have these cookies, you can delete them in your browser’s settings, and even stop it from accepting cookies from this site in the future. I won’t be offended.
