What you keep
You keep ownership of the words, photos, business information, and other content you supplied. Collister Computing returns that material within seven calendar days when requested, at no charge.
You keep your domain. If Collister Computing registered it for you, the transfer starts when you cancel and finishes within five business days. It is free and is not held over an unpaid balance.
The finished site files become yours after six monthly payments. If you cancel earlier and want them, you may pay the balance up to six payments. That choice is not a debt. If you do not want the files, you owe nothing beyond the month already charged.
The full rules are in the Terms of Service and Website Care Plan Agreement.
