Is it safe to pay my subscription online?

Yes, it is safe to pay your subscription online. The approach used by Notarius ensures that credit card data is transmitted directly from your browser to a certified and highly secure payment platform, without ever going through our servers; we never have access to your credit card number.

We require that all payments under $ 1,000 to be made online by credit card, on a PCI/DSS level 1 certified payment platform (the highest level there is). This protects our customers, who enjoy the highest level of security, protects our employees, who do not have to handle highly sensitive credit card information, and is consistent with our certifications.
