iPhone apps from some major companies are reportedly recording how you use them without asking your permission.
Air Canada, Expedia, Hotels.com, Singapore Airlines, Abercrombie & Fitch and sister brand Hollister are among the companies mentioned Wednesday in a TechCrunch report.
They apparently embed "session replay" software -- which lets developers record the screen to see how people use the app -- from a company called Glassbox, so your every interaction is essentially recorded via screenshots.
The software is supposed to mask sensitive data in these screenshots, but the report noted that the App Analyst found that Air Canada's app wasn't always doing so properly.
Some companies sent the captured data to Glassbox, while others sent it to servers in their own domain, according to TechCrunch. None of the companies mention recording your screen in their privacy policies, the site noted.
Abercrombie told TechCrunch that Glassbox's software allows it "to identify and address any issues customers might encounter in their digital experience."
Singapore Airlines said in an emailed statement to CNET that the data "is used for diagnostic and troubleshooting purposes."
Expedia noted that its brands aren't using Glassbox on any of its "native applications for iOS or Android."
"On select Expedia Group brands native applications for Android, Glassbox exists from a prior proof of concept in the codebase but it has been disabled for some time and has not been actively capturing information," a spokesperson told CNET in an emailed statement.
Neither Apple, Air Canada, Expedia, Hotels.com, Abercrombie & Fitch or Hollister immediately responded to requests for comment.
