 FIXME: Purging should probably delete *all* resources associated with the 
exchange.
 But does it also remove the associated transactions?
 
+ToS Management
+--------------
+
+The wallet only stores the last accepted ToS ETag and the ETag last offered by
+the exchange.  The ToS contents are not stored by the wallet database (and thus
+not included in backups).  However, the wallet implementation may cache the
+``/terms`` response on the level of the HTTP client.
+
+In future iterations, the UI might specify the prefered language and content 
type
+for ``/terms``, so that the wallet can already download the full response (not 
just ``HEAD``).
