Yes, it is possible for someone to see if you are looking at their location, depending on the device and services they are using. It is important to be aware of the security settings on the device or service you are using, as well as the privacy settings of the other person. For example, if someone is using a service that allows you to see their location, they could be able to see that you are looking at their location. It is also important to be aware of what information you are sharing publicly, as this could be visible to others. For example, if you post your location on a public platform, it could be seen by others. If you are concerned about someone seeing your location, it is best to adjust your settings or not share your location publicly.
