If you want to give a mind-blowing presentation, Prezi is the tool you need nowadays. And if you want to close your account, you can do that in the Settings page of your online profile.
I’ll show you below with pictures how I managed to remove my profile on a desktop computer:
1 Go to prezi.com/login and sign in
2 Click on your name and select Settings & account
3 Scroll down to the bottom and you’ll see a link: Delete your account
Be aware of the fact that Your prezis can not be recovered if you delete your account.
4 Enter your password to confirm your identity
This is the final step in the removal procedure.
✅ Result
You’ll be redirect to the homepage and your account will be closed immediately.
