If you're currently on a paid plan, on the Your Plan page you can click Manage Plan then Cancel Plan.
Please keep in mind that if you're a seasonal business or you're not seeing enough guests to justify using NextMe's waitlist software, canceling your plan will automatically downgrade your account to NextME's free Lite Plan which you can use until things pick up again (if you are currently on a free trial, your account will also automatically downgrade to the free plan at the end of the 14 day trial period).
Here are our Help Center Articles if you are seeking resources about how to use NextMe.
Rest assured: canceling your plan does not delete your account - you can always log back in with your existing credentials and reactivate by re-subscribing to plan!
However, from logging into your account you are indeed able to:
Delete your own data from the General Settings page
Delete your account altogether from your Business Details page
