You sure can! We do support data encryption between your browser and our servers. This is often referred to as SSL encryption. We actually support a more secure version of SSL called TLS. Modern browsers support this.
To access the website using TLS, just use HTTPS:// (instead of HTTP://) in the address bar of your browser.
Our mobile apps make use of TLS by default, so all of the data in-transit is encrypted when you're on the go.
Transport Layer Security (TLS) is a protocol that ensures privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message. TLS is the successor to the Secure Sockets Layer (SSL).
Hope this helps,
