We collect the following information regarding your tfs.visualstudio.com hosted repository:
This information is collected solely so that the application can access the work item information stored in the tfs.visualstudio.com hosted repository. As a convenience, WorkItem Glass can store this credential information locally on your client device. This information is not stored anywhere else. Once saved, the credential information can be managed through the application Settings charm. If you uninstall the application, the stored information is removed as well.
WorkItem Glass solely uses the credential information to access your tfs.visualstudio.com hosted repository. This credential information is passed to the WorkItem Glass API service, which then contacts tfs.visualstudio.com on your behalf. WorkItem Glass uses a secure transport (https) for any connection.
We do not share your information with anyone. Period.
