If you’ve used Twitter on your Android phone anytime since 2014, you might want to double-check your settings. Twitter disclosed on its Help Center page today that some Android users had their private tweets revealed for years due to a security flaw. The issue caused the Twitter for Android app to disable the “Protect your Tweets” setting for some Android users who made changes to their account settings, such as changing the email address associated with their account, between November 3rd, 2014 and January 14th, 2019.

Though the company says the issue was fixed earlier this week and that iOS or web users weren’t affected, it doesn’t yet know how many Android accounts were affected. Twitter says it’s reached out to affected users and turned the setting back on for them, but it still recommends that users review their privacy settings to make sure it reflects their desired preferences.
