Meta Platforms Inc. announced on Thursday that it has started testing an option for secure storage on Facebook Messenger that should allow users to back up their end-to-end encrypted chats.

"As with end-to-end encrypted chats, secure storage means that we won't have access to your messages, unless you choose to report them to us," the company said in a statement. "We're also starting a test of automatic end-to-end encrypted chat threads on Messenger and expanding other features," it added.

The move comes several months after Meta updated its privacy policy, which included the company's promises to be more transparent and not to collect, use or share data in new ways.
