Google forms have these features that together seem to meet our requriements:

• Verification: We can require users to fill the form from as logged-in users, and to agree to share their email with us.
• Consent: We can require to agree to the license.
• We can show the link to download the data after the form has been submitted.

Demo

Currently the app links to the download zenodo-page directly. This is simple but lacks two features that were listed as requirements:

1. The consent is implicit, not explicit.

This might not be a problem since the license is conspicuous in multiple places:

a. In the landing page "Disclaimer and license" b. Right next to the link to the download page. c. In the download page itself.

2. We have no record of he people who downloaded the data.

This might not be a problem if we don't care who they are or even a benefit if we don't work to deal with the hassle of storing personal data.

A simple solution

A simple solution is for the app to link not indirectly to the download page, first taking the user to a google form to collect the data we want. And only after the submission would provide a link to the download page.
