Security was not an afterthought when building Hourglass. All communication to and from the Hourglass application is encrypted, as is all data at rest. The systems are hosted in a redundant environment dedicated to Hourglass and are regularly backed up.
End-to-End (E2E) encryption is an advanced feature. While all information in Hourglass is always encrypted in transit and at rest, E2E encryption adds another layer of security by ensuring that personal information, such as names, birth dates, addresses, phone numbers, etc. is encrypted with a key that only authorized congregation members are able to obtain. Hourglass servers and administrators have no ability to decipher this information.
