All prayer teams are invitation only, and content on Prayvine is always encrypted through HTTPS. In addition, search engines (such as Google) cannot access any prayer team or prayer request information. We do not provide a search function to look up whether someone has a prayer team on Prayvine.
We cannot prevent prayer partners from forwarding prayer request emails, so you should only invite people you trust to join your prayer community. In addition, we highly encourage good password practices (e.g. using different passwords for different website) and physical device security (e.g. locking your laptop to the table when working at an internet cafe).
