Security aspects of free Community Version

We are planning to introduce this tool in our organization. We want to try the free community version first and then move to a paid version of it. We have few question related to security of our data and application:
1.Since UIPath community version is a cloud based application. Will using this version of UIPath store our application’s data on Cloud?
2. If yes, then how that data is going to be used?
3. Are there other ways in which our application’s data or organization’s data going to be stored or used by UIpath?
4. If yes, how UIpath can assure small organizations like us about the safety and security of their data?
