Given a part of privacy policy text, classify it into one of these categories: 
 (1) First Party Collection/Use (how and why a service provider collects user information), 
 (2) Third Party Sharing/Collection (how user information may be shared with or collected by third parties), 
 (3) User Choice/Control (choices and control options available to users), 
 (4) User Access, Edit, & Deletion (if and how users may access, edit, or delete their information), 
 (5) Data Retention (how long user information is stored), 
 (6) Data Security (how user information is protected), 
 (7) Policy Change (if and how users will be informed about changes to the privacy policy).

Security measures are not mentioned or unclear.
Data Security
The text states that "we work hard to protect user-information off and on line" and that "we take steps to make all information received from users secure". These statements indicate that security measures are taken by the service provider. The text does not specify exactly what these measures are, so the answer is Data Security..
