Capacity Tracker has two different implementations depending on your Jira platform:
Jira server and Data Center
Capacity Tracker for Jira Cloud uses the Atlassian Connect framework and works by exposing a multitude of REST APIs. The app is hosted in our own infrastructure and your Jira instance interacts with it by calling those APIs.
To provide the best possible service, some data will be stored in our own storage layer (AWS DynamoDB), which includes:
Jira instance details (base URL, date of installation / modification, etc). This allows us to use the Atlassian Connect framework.
Team settings (working days, holidays)
For every user in your board: user account ID, role, daily capacity
API Refresh tokens
Moreover, some global settings will be stored directly on your instance:
User days off
If you use a firewall, you may need to white-list our production endpoints:
Capacity Tracker for Jira Server and Data Center is a self-contained application that will be downloaded and installed on your own Jira instance. Your data will stay on your instance and will never be sent anywhere else.
