3.1.2 Information about Users

Castle may have access to Personal Information about Users (“User Data”) in the course of providing its Services to a Client.

We consider User Data to be confidential and do not use such data for any purpose other than to provide the Services to our Clients.

Our Clients use code such as JavaScript code or software development kits (“SDKs”), collectively “Agents” within their mobile, web and other services that enables the Castle Service to collect information from and, where available, link Users across Clients. Our Clients have control over the Agents and may remove or disable it at any time.

Castle has access to User Data only as requested by the Client and only for the purposes of performing Services on the Client’s behalf.

9. How we protect your information

We take steps (such as administrative, technical, and physical procedures) to ensure that your information is treated securely and in accordance with this Policy. Some of the steps we take are limiting access to information through username and password credentials and multi-factor authentication and using industry-standard Secure Socket Layer (SSL) encryption technology to safeguard the account registration process and sign-up information. Other security safeguards include but are not limited to data encryption, firewalls, and physical access controls to building and files.
