Contact availability
FeeDeck is still a young site. A dedicated public inbox for seller-feedback and
policy questions is being set up and will be published here once it is ready.
In the meantime, the site keeps its methodology, editorial standards, and page
review notes public so ownership and publisher intent are visible even while the
dedicated inbox is being finalized.
What to include
If you are reporting a calculator issue, include the page URL, the numbers used,
and what result you expected. That makes it much easier to reproduce the scenario
and review the logic quickly.
