How the free allowance and privacy work
Only a successful new calculation uses one of your five. Loading, editing and invalid dimensions use none. Retrying the same interrupted request in the same trial session recovers a stored result without another use. If the session is no longer available, a retry may start a new calculation.
Numeric dimensions are sent to our server. An essential cookie keeps five uses per product in this browser profile for 180 days. Anonymous counts, request hashes and geometric results are retained for up to 180 days to recover interrupted requests. No files or free text are sent to the server; front text and colour stay in the page. Daily address hashes limit abuse and are removed at the next cleanup after the UTC day ends. Clearing cookies, private browsing or another browser starts a separate profile. An interrupted request may be saved temporarily in this tab. Privacy details.
