For an even more secure and confidential experience, you can use the new secure Liberty browser, which is integrated into the Qwant application. It gives you the option of creating an encrypted safe inside your mobile phone that nobody else can open. Thanks to its SIM & PIN technology, it allows you to keep sensitive data that you want to be able to reuse easily on your person, for instance when making online purchases. All of your data is encrypted with a key that doesn’t leave your phone.
