Privacy
robruncheat.org is a static catalog. It does not ask you to create an account, and it does not include a payment form. Buy buttons send you to checkout. That site collects whatever its own checkout requires, under its own privacy policy.
A message sent through support is used to answer you. It is not added to a public list and it is not sold.
The host that serves the site may keep ordinary connection logs, such as a browser address and the page requested. Those logs are for security and operations. This catalog does not add an analytics tracker of its own.
The pages do not set a tracking cookie. A host or a font provider that the browser contacts may keep its own technical data. Checkout cookies, if any, are set after you leave for checkout.
Privacy questions go through the support page.
