Tired of Google+ already? Here are the steps to delete your account:
- Sign in to Google+ in a desktop browser.
- Click your full name (or email address) in the Google+ bar at the top of the screen.
- Click Account settings.
- Click the Account overview tab.
- Click Delete profile and remove associated social features.
- Confirm your choice.
This is a permeant change, and cannot be undone. If you re-join Google+ in the future, your previously-entered information will not be present.
This does not change any of your other Google services tied to the account. Everything will be as it was before you joined Google+.
