Am I missing something obvious, or is there nothing in the CiviCRM Spark sign-up process that says what the billing period is? It says 'CiviCRM Spark Hosting - $ 9.50' and that it'll renew automatically, but not how often. Does anyone know? I'm guessing monthly, but would need to know before trying it. Or even better, is there a free trial somewhere that I can't see?
It's per month. Thanks for raising this issue, we will clarify the site.
You can also contact us on the CiviCRM chat: https://chat.civicrm.org/civicrm/channels/spark or by email: email@example.com.
As per the T&C, you can also ask for a refund after 30 days, if you were not satisfied with the service.
Looks an interesting service and will suit many and certainly a good way of getting started. I can't see a contact email for the service or a list of the extensions included. I think I've probably already grown beyond this service as I am using a few extensions, but had it been there when I started, it would probably have been quicker that getting it going on another hosting provider.
But to answer you question - it does look to be monthly - see the T&Cs linked from the signup page (direct link https://civicrm.org/spark-terms-and-conditions).
