Simply uninstalling the client does NOT cancel your account or terminate your subscription. To cancel your account, click the Account button in the SpiderOak application, then choose the red Cancel Account button. This will close your account and purge all data from SpiderOak's servers. You can also cancel your account online by logging into SpiderOak.com and choosing the Account tab.
If for any reason you need to reopen a closed account, please contact SpiderOak Support immediately.
