If you want to remove your account on Flipboard, a mobile app that combines social media and news articles, you can easily do that in the Settings of your account.
I’ll show you below how I managed to close my profile permanently using a desktop computer:
1 Go to https://flipboard.com/signin
and log in by entering your email address (or username) and password on their site.
2 Select the picture in the upper right corner. Then you can choose Settings.
3 Scroll down to the bottom, where you will notice a Delete account link
4 You’ll be requested to re-enter your password
Your account will be removed and you’ll be redirected to the Flipboard homepage. Mission accomplished!
