Privacy

What you type is sent to this server to be calculated, and that is all that happens to it: it is not stored, not written to any database, and never passed to anyone else. An uploaded certificate is read in memory to find the figure it carries, then discarded in the same request — it is never written to disk and never leaves this server. Nothing is kept once the answer comes back. There is no analytics and no tracking. The server keeps ordinary technical logs, including IP addresses, which are personal data under the GDPR; they exist to keep the service running and secure. You may complain to the CNPD.
