yes, by default the notes get encrypted and then encoded into base64 on the client side before they are sent to the server.
what happens to a note after it has been read?+
a note is deleted from memory upon fetching its contents, this means that even if your decryption keys are bad it will still be deleted.
where are notes stored?+
notes are stored in memory on the server, meaning the notes are never saved to a file system. however as memory size is limited, your note may get deleted to allow new notes in. oldest note gets deleted first.
what data is processed?+
the only other parameter apart from the note contents (encrypted by default) is time of when note was created, this is to allow deletion of notes in memory allowing oldest note to be deleted first.
are you using any trackers or loggers?+
