We recently used Kobo Toolbox (<a href="http:&#x2F;&#x2F;www.kobotoolbox.org" rel="nofollow">http:&#x2F;&#x2F;www.kobotoolbox.org</a>) for a health related survey in a developing country... The Ministry of Health required the data stored locally to be encrypted on the device and during sync (not just over https), which caused some problems for deployment. That will be an absolute requirement from any gov that looks to adopt the tech. Not sure if it was a PouchDB or Kobo shortcoming.
