We noticed that our cellular numbers seems to be available. One associate called a lead and when answered, the other person told her full name. After the conversation we found out they the person uses an apps called CallApp in her android. We searched her number (and ours) and found sites with the associates name and address for example 'locatefamily.com'.
Please explain how this is done? And is our personal info is up for grabs? How can stop this?
Thank you in advance
