Nit: Don't use using directives unless they save a significant number of lines.

Done.

Nit: Indent 4, not even (2 places)

Funky.  I copied these directly from search_terms_data.cc.  I'll fix those, too.

+  // Android doesn't use the rlz library.  Instead, it manages the rlz string
+  // on its own.
+  return SearchTermsDataAndroid::GetRlzParameterValue();

I suggest returning the value directly here and below.

You could do this by making the strings globals, so anyone could just set them
directly, and you can read them directly here.  I'd probably do this.  It's
extremely simple.

If you like, you can stick them in a namespace or (otherwise empty) struct or
something, for name scoping.  But I don't think the getter and setter buy
anything but one more indirection.

Kept them inside an otherwise empty struct to keep it tidier, but removed the
setters and getters as requested.
