  • Whatsapp contacts - if they're onnm contacts am I on theirs? I have the phone number of an old friend stored on my iPhone and they also show on my whatsapp contact list… Does this mean that they still have my phone number stored in their phone and also have whatsapp installed on their phone? The chat thing says they haven't been seen since 28th sept? If they didn't have my number on their phone would they still show as one of my contacts on whatsapp?

I cleared out everything that was his but I hate the part where each time my parent's add a new contact to their phone, everything syncs over to my contacts, so I'm scrolling down my list and see a new person I don't know but my parents do. Is there a way to change this?
