Does 2Do encrypt synced data?
2Do uses a secure SSL connection when syncing to the cloud service of your choice (Dropbox, iCloud, CalDAV and Toodledo). It is then up to the selected cloud service to store the data however they wish to store it. The stored data is thus as secure as the rest of the data in your account. 2Do does not explicitly encrypt the stored data on top of encryption offered by the storage device or service.
