The point of this app is that you share a link with your peers, whether they're based in your office or in an office in a different country. This is a bit different from completely anonymised data from statistically similar market segments (and possibly more useful, since people at the same company are likely to have similar perks and benefits etc.)
Perhaps it would be useful to be able to view the results in any currency you desired. But already we're entering scope-creep territory :-)
