FieldClock takes security very seriously. All communication with our servers is encrypted with industry-standard cyphers. Even with that in mind, we don't even touch the most sensitive data. Your credit card information is sent directly from your browser to our payment processor. The card information never touches our servers and can't be seen by our network technicians or developers.
All payments are processed by Braintree (a PayPal company). More information about Braintree's security.
