     <h3>How we use TLS and HSTS based tracking</h3>
     <p>The demonstration of the TLS and HSTS based tracking for educational
     purposes is the sole purpose of this website. The website uses TLS and HSTS
-    based tracking to encode a user defined string. The user defined string is
-    not decoded on the server. The user defined string is only decoded in the
+    based tracking to encode a user-defined string. The user-defined string is
+    not decoded on the server. The user-defined string is only decoded in the
     browser. The decoded string is not transmitted.
     The string can only be removed by clearing the browser data. The
     string is arbitrary and must not contain personal information.</p>
