Can the code be used by more than one person at the same time?
No. The code can only be used to create one Chromville World account. One code may be used for more than one device at the same time only in special cases. People involved will be informed about this.
Can I install one code in more than one device?
The code gives you the opportunity to create an account for the Chromville World package. This account can be logged into all the devices that you need. In spite of this, the code (or account) doesn’t allow you to start the Chromville Science app in two devices at the same time.
