Whenever you go to the internet and, regardless of the browser used, you systematically leave traces that provide information on everything you have done there. Going back in the history of the browser for example, we can know all the websites you have visited, or even the research you have done during your last connection. These traces are found both on your device and outside of it (for example at your internet operator or with the administrators of the computer network used).
When you share an Android smartphone or tablet, you don't necessarily want other users to know what you're doing online. To prevent this from happening, you can use private browsing.
What is private browsing?
Private browsing or incognito browsing is a feature offered by most web browsers. It allows you to surf the Internet "without leaving a trace" on your device. When you open a normal web page, certain elements such as the history of the sites visited, the history of searches carried out, temporary files or cookies are automatically stored on your device, and accessible during the next openings. By switching to incognito browsing, all these elements are systematically erased once the browser is closed.
It should however be noted that browsing in private mode does not mean that you are surfing anonymously, your internet service provider being able to access your browsing data at any time. In addition, if you use your company's connection, the administrators of your company's computer network can also know everything you do on the internet if they wish. This also applies to webmasters of websites who automatically have access to your IP address, as soon as you connect to their platform.
On the other hand, even if you use browsing in incognito mode and you voluntarily download files from the internet, or save favorites, these will remain on your device after closing the browser, and other users will be able to do so. have access.
