I was also initially put off WhatsApp because I heard the encryption makes it more difficult for police to access information should a crime be committed. I seem to remember this was backed up  by a member here being contacted by the police regards a punter she had as a client went missing, they had found he had contracted her, but could not break the encryption to obtain a location fix. Going off the recent coverage of the missing woman in the Blackpool area, sounds as if the police can now obtain whatever they need from WA if they need to.

I speak as someone who's armed robber was found only as a result of data from calls, texts, mobile signal.

My personal phone has WhatsApp which I use for family etc. but my work phone belongs in a museum so only calls and texts on there. I occasionally get asked about communicating on W.  but my polite reply stops that line of convo with no problems.

Merged

Im like, what difference does it make? 

Some say it's to send me a photo or chat.

Umm I'm not interested, but it's another question to add to ping pong which just becomes off putting.

I don't mind using WhatsApp with my regular guys but I've had some unknown people try video call me which I'm not comfortable with at all so I block automatically. All numbers are checked before I reply too [off topic removed]
Some have a long list of bad feedbacks
