+## 🔒 Encryption: how it works
+
+Encryption works by issuing symmetric keys (basically a generated password) and
+encrypting it with the local SSH public key generated by the open-source
+[charm][charmlib] library. That encrypted key is then sent up to our server.
+We can’t read it since we don’t have your private key. When you want to decrypt
+something or view your stash, that key is downloaded from our server and
+decrypted locally using the SSH private key. When you link accounts, the
+symmetric key is encrypted for each new public key. This happens on your
+machine and not our server, so we never see any unencrypted data.
