As of my last knowledge update in January 2022, the steps to delete a Yubo account might have changed. To delete your Yubo account permanently, you can follow these general steps:

Open the Yubo app on your device.

Log in to your Yubo account with your username and password.

Once you are logged in, go to your profile by tapping on your profile picture in the top left corner.

In your profile, look for settings or account settings. This is typically represented by a gear icon.

In the settings menu, you should find an option like "Account" or "Account Settings."

Look for an option to delete or deactivate your account. This might be labeled as "Delete Account," "Deactivate Account," or something similar.

Follow the on-screen instructions to confirm the deletion of your account.
