I have turned off the location of all the software, but there are still advertisements that know my location. Is this kind of advertisement illegal?

Personal computer experience, it is not enough to turn off GPS, but also need to carry out authority management, restrict and turn off some applications to send notifications, access mobile phone address books and short messages, and prohibit access to and reading from storage disks. General applications can be turned off without receiving notification advertisements from applications. Some applications have been authorized to you when you use them, such as e-commerce platform applications. Your purpose (such as shopping, making money) has been truly told to it, your real name, address, address book, short message and circle of friends, so it can send you some advertisements accurately. Most of these advertisements are commercial advertisements, which are not illegal. If you don't like this advertisement, you can delete the application. In fact, you can ignore it and manually delete the advertisement yourself. Advertisements sent by mobile companies do not count. Some advertisements are messages you leave when you use public ***WiFi. In short, these advertisements are nothing more than recommending goods to you. Ignore them. All software has turned off location, and some advertisements know your location accurately. These are all commercial advertisements, which are not illegal.
