A Twitter glitch left some Android users' protected tweets exposed since 2014.
The security flaw disabled the "Protect your Tweets" option for some people who changed their settings, such as updating the email address associated with the protected account, between Nov. 3, 2014 and Jan. 14, 2019, the company wrote in its Help Center Thursday.
Those using the iOS version of the app or Twitter for web weren't impacted.
Twitter fixed the issue on Jan. 14, but isn't sure how many accounts were affected, so it's recommended that you double check your settings if you're an Android user and want your tweets protected. The company is contacting people it knows were affected and reactivated the protected tweets setting for them.
