Qualifying for church/house of worship pricing is contingent upon usage strictly being church-related. For example, this could include organizing worship teams, greeters, meals for families organized by the church, food for small groups, outreach events, ministry crews, prayer chains, etc.
A church subscription does not include activities that are held within the church but not directly related to the church. For example, scout troops that meet at the church, even if chartered by the church, do not qualify. Nor do sports teams that meet at the church and who are sponsored by the church. Groups such as these fall under the non-profit tier and are encouraged to use the non-profit Platinum plan.
