Cancelling a subscription is very easy and can be done at anytime.
Please also note you may also Pause your Subscription which unlike Cancelling still provides access to uploaded and shared models whilst pausing your billing.
To Cancel:
Simply login to app.realar.com (ensuring your email/login is correct for the subscription you would like to cancel)
Select Account (from the top Navigation)
Under My Account, click Cancel Subscription
You should then receive an email confirming your subscription :)
You may also in addition follow Delete My Account which ensures data privacy and removes from platform email messaging.
