Proposal to add a splash screen with text and an agreement checkbox that shows up on a fresh install and is impassible until the user agrees. Candidate text below (from http://brcaexchange.org/about/dataSubmissionPolicy):

Perhaps we'll include only the "Disclaimer and Data Use Policy" section in the text, since that applies to end-users. If we decide to revise the policy (e.g. to allow user-submitted data), we can re-display the splash screen in a future release.
