Data Protection and Security Toolkit
Sandbox environment allows you to use these apps with a set of Projects, Issues and Worklogs used by Actonic for demo purposes. You may create your own projects, issues, worklogs during the lifecycle of the Demo instance.
Demo sandbox data is shared publicly. Do not create any entries which may contain your organisation or personal data!
Please be informed that Demo instance resets every 3 hours starting from 00:00 UTC+0.
Please do not change the credentials when you are logged into the instance since it will prevent other people from logging in during the lifecycle of the instance.
