Technically YES - but only for a brief moment, and we do not store it unencrypted. Read more about this under "Is TUArmor zero knowledge?
". Your data is sent to us through an encrypted channel (SSL), and it is then prepared for storage by encrypting it using your optional secret on the server. After encryption the data is then saved in the database. If you used an optional secret, the data in our database is inaccessible without that secret. The same can be said for a key-me-please post, as those are basically secrets created from browser accessible data (IP address, user-agent string, etc) The same is true on the way back out. When the data is viewed, and the optional secret is supplied, we decrypt the data at the server and display it to the user over SSL. Again - we don't store this information unencrypted, but this does not meet the definition (in our opinion) for true zero-knowledge system.
