 ## Features
 
 - server cannot decrypt contents due to client side encryption
-- view and time constraints
+- view or time constraints
 - in memory, no persistence
 - obligatory dark mode support
 
 ## How does it work?
 
-each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory and never persisted to disk.
+each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The
+<code>id</code>
+is used to save & retrieve the note. the note is then encrypted with aes in gcm mode on the
+client side with the <code>key</code> and then sent to the server. data is stored in memory and
+never persisted to disk. the server never sees the encryption key and cannot decrypt the contents
+of the notes even if it tried to.
