People are downloading a messaging app for you?

I wish I was you. Here no one wants to download a second messaging app just to chat with one person. Why would they? Everyone is on WhatsApp. No one cares about privacy and that the app is owned by Meta (Facebook).

Ahh so this is a US only thing. What you are saying is: the united states of america is fucked.

Good luck.

Ehh?? How would that app know about the data the store potentially collects?

Many stores have installed Bluetooth beacon tracking that will monitor all customers cell phones

What? No one is doing that. Why would they? What if you have bluetooth disabled all the time like me because you don’t have any Bluetooth accessories, or to save power, or because Bluetooth is insecure.

Self checkouts also have cameras that can identify biometrics

??? The camera is just to check on the customers if they are scanning everything properly and not stealing. A human is reviewing the footage. A human is going to confront you if they detect you not scanning something.

They have absolutely no reason to store the video footage or even sell that to anyone. Besides, no one would buy that. Not even the app from OP‘s post.

You should put down your tinfoil hat.

How would they be able to know that OP was the one making the purchases and not the cousin?

The cousin is the one uploading the picture.

everyone is on Signal

Where? I‘ve Signal installed and literally only 2 contacts use it.
