Sex toy fans who purchased a vibrator were horrified to discover their intimate sessions were secretly recorded on an app that comes with the toy.

Lovense, the Hong Kong company behind the vibrator, reported a “minor software bug” after users discovered its remote-controlled vibrator app recorded sound files and stored them on phones each time the toy was on.

With this bug, the cache file was stored on the user’s device until the next session, which overwrites the previous cache file.

A customer revealed the issue on Reddit, insisting they never wanted their “entire sessions” recorded in the first place.

The user, called tydoctor, wrote: “The Lovense remote control vibrator app… seems to be recording while the vibrator is on.”

They added: “I was going through my phone media to prepare it for a factory reset and came across a .3gp file named ‘tempSoundPlay.3gp’ in the folder for the app.

“The file was a full audio recording 6 minutes long of the last time I had used the app to control my [partner’s] remote control vibrator.”

In a bid to calm the horrified user, Lovense replied on Reddit saying: “Your concern is completely understandable.”

It added, “… rest assured, no information or data is sent to our servers. This cache file currently remains on you phone instead of deleting itself once your session is finished.”

A company representative told The Verge that the bug has been fixed and the cache file will be eventually deleted.

The sex toy manufacturer’s blunder comes weeks after security researchers reported their butt plug was not safe.

Penetration testers claimed they were able to hack into the Lovense Hush.
