House sitter memberships expire after twelve months if you choose to not renew your account. We do not keep your credit card details and would never presume to automatically renew your annual membership.
Instead, we sent you an email reminder one month before your account expires, with an invitation to renew your membership. If you go ahead, you will then have to re-enter your credit/debit card details again.
If you wish to cancel your account immediately, select the 'Cancel account' link from the bottom of your 'My account' page, which is available on your Dashboard. You can also email help@mindmyhouse.com to arrange the removal of your membership account from the site.
