WhatsApp "encryption" & privacy

[smogsy]

A lot of you may may know this already & I do too but its pretty obvious in this example so wanted to share

My wife is on a school trip, the only time she get H/3G signal is in their accommodation when the kids are in bed.

as I our anniversary is coming up I texted a message suggesting Edinburgh to see the pandas & shared 1 screenshot of booking.com (picture didn't go through)

we shared the word Edinburgh and trip once

she loaded Facebook up on her phone later that night. every add is about edinbough/trip/booking.com
I don't have Facebook on my phone but logged on out of interested 0 ads.

so whatsapp says convo are encrypted, but i guess if its decrypted on your phone Facebook thinks is ok to scan your messages from another app? (wonder if this would work on iphone due to isolation apps) wife is on android

Did she open the booking.com link? If so thats probably what the tracker/cookie ad stalker thing, picked up on.

nope she couldnt even download the screenshot of booking.com i didn't give her the link, nor did she go their

the only way possible is facebook reading whatsapp chats

Your home is the same wifi network. The advertisers probably tracked you and also target her as they know you're in the same household or on the same IP frequently.

sounds feasible, although pihole blocks most on our network specially google but possible

Any chance she spoke to a colleague about it and the phone's microphone picked it up and went from there?

I've had two very specific incidents of instagram reels recommending me vids about things i've been chatting about in the phones vicinity within an hour or two of the conversation, it's taking in everything you say.

very possibly might find out tonight
