Usually when this sort of thing happens someone searched for something or a related term in the previous 30 days (typical retention period in “hot” storage for such features) and doesn’t remember doing the search.

Most people, myself included, do so many searches so casually that we don’t remember doing it much of the time.

Not coincidence. Not "bank purchase history" shared with google- in most cases banks and credit cards don't know item level detail. Lots of ways this data flow could happen, at least in the US. Happy to go through specific details I have seen if you want to share more about this, but two high level points 1. Remember that when you purchase something, the data about the purchase is BOTH yours AND the entity from whom…

> Remember that when you purchase something, the data about the purchase is BOTH yours AND the entity from whom you made the purchase.

This is wrong. Because in my case the information is highly personal, while in the shop owner's case it's just business information.

Opt out of VISA marketing https://marketingreportoptout.visa.com/OPTOUT/request.do Second, disable GPS, and cellphone tower ID reporting (root needed.) So Google can't correlate you with sales records. At the moment, there is no way to disable Google AGPS spying on the stock Android. Third, block Google apps from reading your IMEI/IMSI/serial number, so they can't get AGPS data from your cellphone provider if it sell…

Is there an intl equivalent?

March 2020, heydays of coronavirus paranoia. I came back home from somewhere, put my keys onto the dining table and went to the bathroom to clean up. My girlfriend, upon seeing the key-chain on the table started reproaching me for being careless about hygiene. When I returned from the bathroom I saw her washing the key-chain in the kitchen sink. This time I got angry and asked how come she hadn't thought that the usb…

Unfortunately, though this is an excellent story, this is just an example of a bias known as "frequency illusion". It happens with a lot of things, like seeing the clock at 11:11 more than you do at 11:09. Or seeing lots of your make/model car but being blind to the hundred of other variants on the road. How many times have you opened up your laptop and not seen a Facebook add for something you just did, or something…

This probably could explain most people's accounts of this, but I've been approached by companies who offered large lump sums to include their SDK which required microphone access in our mobile app, in order to fingerprint what our users were watching on TV while it was open, nominally to see what ads they were seeing. I wouldn't be at all surprised if they or others were going a good bit further than that and trying to run speech recognition on overheard conversations, unless it's illegal somehow.

AdTech is frankly a revolting industry.

How does Google link the real life person who bought Voltaren at a store to the online account or fingerprint that browses the Internet?

How does Google link the real life person who bought Voltaren at a store to the online account or fingerprint that browses the Internet? Often, through the payment. People use the same payment methods in the same stores over and over. This data is accumulated by the stores, and sold. if you signed up for a "points card" or some other gimmick to get 2¢ off something, the personal information you used when you signed u…

Hmmm....

Use cash!

Many words have multiple definitions, as you are surely aware. Legitimate is one of them.

yep, all the definitions of legitimate equivocate it to legal/lawful. except here, y'all want it to mean not-lawful. I'm legitimately not smart enough to continue this conversation.

Depends if morals matter.

If right and wrong are important then "legitimate" encompass them. So it s possible for something to be legal but not legitimate.

There are not a lot of legal but absolutely immoral (the other way, illegal but legitimate - plenty) the actions of the FANG IMO definitely fall into the category of legal but illegitimate.

Because to me good and evil are important considerations

In order to bootstrap adoption of CCs, the banks pushed for a law in the 60s that put all the fraud liability on the banks, not the card users (and, to a lesser extent, not on the merchants). Your CC purchases are quite protected and it's easy to dispute a charge (apparently a very big deal in the phone and online sex businesses). As debit cards became popular here (well after Europe) the banks push them hard on peop…

So here's the thing - I don't understand the liability thing. At least here in the UK I have disputed transactions on my debit card several times and every single time the charges were reversed during the phone call, I had the money back instantly. Is that only available for credit cards in the US?

That is correct.

I don't buy the speech recognition, nor have I seen it offered.

But the tv 'recognition' is a big part of selling ads on connected tvs, vizio, roku etc.
