You can also tap on the 'Surprise' button and you will get a random product view from one of the most popular products in the USA recently. Great for present discovery.
The app does not track you in any way. None. We don't do that.
However, once you go outside the app into Safari, the sites you visit will possibly track you as they normally do.
