CALE service has a cost of 3€ monthly (up to 3 Screens)

This represents about 0.10 € per day. It used to be free up to 3 screens but it cannot be like that forever. Because is not free for us to maintain server costs and the time we dedicate to create CALE API and services.
If you need to use more than 3 displays we kindly ask you to support our project as Github Sponsor with at least 10 u$ per month if you use the screen administrator in your office to display the meetings for your business.
We will update your account with a higher number of Screens to display dynamic content and you will get also support priority so we can handle any problems that may arise using our service.
