Using apps for check ups

Your results will be in stored in the cloud. And yes your info is sold to all and sundry.
And, they use a lot of power. Even when your device is switched off they are still gathering info.
I have as few as possible.
They ( the tech giant’s) persuaded the public that is a nice easy way to access the sites you need. They left out the part where they are making obscene amount of money from selling on your details.
My son in law works for a multi national company. If you made an appointment to see him he would have your favourite coffee and biscuits ready for you, how, because his company have that information from your store card. All perfectly legal.
And nobody has challenged it.
The one tech company that is of concern gathering our health info is Palantir a huge tech company that own and run our NHS computer systems.

Thanks petra That’s much as I thought.

Thanks, Petra, this has come as an eye opener re the inf from stored cards. I only have stored cards with a few sites I use frequently like online grocery shopping, and I suppose it would be useful if someone offering me coffee knew that I only drink decaff😂 but in general I'm horrified by this.

With the info above I havnt even touched the surface.
Did you think that the supermarkets offered these store cards for your benefit 😂
You don’t even have to buy something now for them to target you. CCTV picks up on what you’re looking at. That is timed.
That means that if you stopped and looked at an item for say 4/5 seconds big brother knows you’re interested.
I sometimes wish I hadn’t gone down this rabbit hole because once you know it, you know it 😱

That’s worrying about the NHS information- especially when you think about the glitches they announce.

Sainsbury’s store card is either a sales technique or a badly managed system.
On a good week, the discounts on my 10 personalised favourites contains 2 things I actually buy. Reading your last paragraph, maybe it’s because we just walked past them (DH walks very slowly.)
