These brands have my details without my consent and I feel it's a problem to privacy
Recently, I was looking for a product and I've been getting a lot of ads related to that. The offers were tempting so I opened the website from the link available on that ad itself on Instagram and go to checkout to see the final price. Surprisingly it knows my name, address, phone number and everything. I've never given my phone number to any of these sites neither visited them. I've been receiving multiple SMS's and WhatsApp messages after visiting those sites. I know instagram listens to you and all but how does it get your details and give it to those brands I've never signed up for?
So my question right now is that where do these websites get my details from that too accurately just from a click on Instagram. My Instagram doesn't have my phone number linked and also I didn't open those websites from my main acc so definitely there's no chance that instagram has added my details over there. I've been wondering about this for the past few days
