Don't panic, but your iPhone can see all your nudes - and it's been storing them away in their own special sordid album for over two years now.
Since the launch of iOS 10 in June 2016, your iPhone has been identifying all of the pictures you take in your underwear and filing them away in a tidy album entitled "brassiere".
Go on, try it. Go on your Photos app, type in "Bra" on the search bar at the top and see what pops up. You might get a bit of a shock.
The image recognition technology was slyly added to the new operating software in the Photos app - powerful "deep learning" tech that allows your phone to identify and sort the photos on your phone using Artificial Intelligence.
But it seems that the AI hasn't quite got the "brassiere" theme nailed just yet - many users have found that perfectly innocent photos of themselves in vest tops, or ones revealing just the tiniest bit of cleavage, have been added to the album.
The first realisation that Apple had been categorizing pictures that were perhaps better left uncategorized and left never to see the light of day again came on Twitter in October 2017.
Since then there have been huge numbers of other users who did not know about the feature taking to social media to warn their friends.
Apple stressed at the time they released iOS 10 that the software was totally local to each device - your "brassiere" pictures are just between you and Siri (but he's a total freak).
Just to clarify - there's no strange sweaty man sat at Apple scrolling through every picture you've ever taken and assigning them to different categories.
But it has opened up a wider debate on exactly how much technology has come on to be able to recognize your pictures in such detail - and to what extent that tech could allow companies to tap into every little aspect your lives.
Replying to another shocked "brassiere" user last week, one person said on Facebook said: "The other week my husband and I were watching a program on tv that was about paddle boarding as a way to get fit I had my phone with me went in the kitchen opened Facebook and the first thing on my feed was an advert for groupon and the top of that advert was an offer for a paddle boarding session.......they hear you."
Another replied: "This is what happened to me!! Was talking to my mum on the phone about hose pipes, an hour later it came up on Facebook with groupons hoses."
While people online are generally creeped out by Apple's antics, their policy of categorizing images local to each device is concerningly different to how Google do things.
If you have enabled the recognition software on Google Photos, it will categorize your photos exactly the same as Apple does - except it stores your photos on its Google servers in the cloud, instead of just on your device.
And, interestingly, there are over 5,000 categories you can search - from "Broccoli" to "Button Machines" - and while there are "Bra" and "Brassiere" categories, there's no male equivalent such as boxers, briefs or pants.
Come on, if you're going to recognise, identify and categorise people's nudes and completely creep them out in the process - at least do it fairly.
