feat(zoya): Review the research findings against the node acceptance criteria

Outcome: done
Changed: none
Verified by: not verified - review-only node; repo cross-checks done (devplacepy/templates/docs/contact.html:5, devplacepy/templates/admin_settings.html:192, devplacepy/database/schema.py:1746, devplacepy/static/app-store-badge.svg)
