Upstairs knows the location downstairs, and everyone else knows which floor I m on

Sorry to hear that. If you find that someone upstairs knows your location, it may be because they have some way of being able to observe your activity, or they have obtained your location information through other means.

If you want to protect your privacy, consider taking the following steps:

1.Make sure your room or activity area has adequate privacy protections, such as using curtains or blinds to cover the windows, or using other means to cover your activity area.

2.When you need to deal with something sensitive, you can choose to do it in a public place or in the presence of other people, which can increase your security.

3.If you suspect that someone has illegally invaded your privacy, you can report the matter to your local police or other law enforcement agency, who can provide the necessary help and guidance.
