A user on Twitter has informed the world that if you search the word “brassiere” in the photos app on the iPhone, the photos featuring bras are automatically grouped into a category.

ATTENTION ALL GIRLS ALL GIRLS!!! Go to your photos and type in the ‘Brassiere’ why are apple saving these and made it a folder!!?!!?😱😱😱😱 — ell (@ellieeewbu) October 30, 2017

According to The Telegraph, Apple isn’t actually saving the photos in a specific folder, they are only being stored locally on the device.

The feature was actually introduced with the launch of i0S 10 last year, however it seems many iPhone users were unaware it even existed.

By putting images in groupings, it makes searching for specific photos easier for Apple, using facial recognition and machine learning technology to work out the objects in your images.

However, if you search boxers or briefs no category comes up.

It's true. If u type in "brassiere" in the search of your iphotos, it has a category for every boob or cleavage pic you've ever taken. Why. pic.twitter.com/KWWmJoRneJ — christine teigen (@chrissyteigen) October 31, 2017
