App is 100% SharePoint-hosted - all data is stored securely on the customer's SharePoint environment.
App's data is never leaving your SharePoint env, we don't have access to your data and we never see it.

You can download the fully functional trial version from the SharePoint Store, which is explained step by step in the above illustration.
If you have problems with app installation, please read the question "I cannot install SharePoint app on my SharePoint Site" from our Technical FAQ.

The Time-Off Manager Pro workflow consists of four states: Pending Approval, Approved, Rejected and Cancelled. When a user submits a request, the system reduces the user's leave balance accordingly. The request is given Pending Approval or Approved status (depending on time-off policy).  The user can cancel a request before the leave starts – the leave amount is returned to the available balance and the request disappears from the list. Cancellations of ongoing and past requests require administrator action.  The system sends an email notification of any requests to the manager for approval, and email notification of approvals or rejections to the employees.

As Administrator:
1. Configure Settings (section Administration->Settings)
2. Configure Public Holidays (section Administration->Public Holidays)
3. Configure Company Departments (section Administration->Company Departments)
4. Assign user roles: Manager and Administrator (section Administration->User Roles ). There is no need to assign regular User role, because this role is given by default -every user with access to the Sharepoint parent site (where the app is installed) also has access to this app as regular user.
5. Create user profiles (section Administration->User Profiles)
6. Create or edit time-off types (section Administration->Time-Off Types )
7. Assign time-off balance to the users (section Administration->Time-Off Balances )

As Regular User:
1. Click "Create new" tile on the main page and submit request.

If you need help with configuration, please watch video guide

The app offers three predefined user roles: Regular user, Manager, and Administrator.
Each user role has the following permissions.
Actions available to regular employees: 
• Submit new leave requests
• Cancel a leave request (only before the leave starts)
• Check own time-off balance
• See current (future and ongoing) leave requests of other employees
• Submit requests on behalf of someone else*.

Actions available to managers:
All actions of regular employees plus:
• Approve or reject leave requests waiting for approval*
• Submit requests on behalf of someone else* 
• View all the requests and time-off balance of subordinates

Actions available to administrators:
• Cancel any leave requests
• Customize system settings 
• Assign time-off balances to employees
• Define public holidays, special events, email templates
• Assign user roles
• Access to time-off report

* - depends on system settings

There is no need to assign regular User role, because this role is given by default - every user with access to the SharePoint parent site (where the app is installed) also has access to this app as regular user.

App update process is described here and also on our Technical FAQ, question "How to update SharePoint app?"

User list is pulled from SharePoint User Information List (built-in SharePoint feature, here is more info)
SharePoint user is added to the User Information List after first login to the SharePoint Site.
After first login, user will be visible in the user's drop-down list.

We cannot extend trial period remotely, because app is SharePoint-hosted and our company doesn't have access to the customer's SharePoint env., however you can uninstall an app and install it again to "reset" 14-day period. (this operation removes all app data and configuration).
