In the Administration Area, under Distribution Usage (Direct Link), you can analyze the status of the bandwidth used in your account.
If you access the Distribution Usage (Direct Link) option, you will see the list of projects and the amount of data consumed by each one.
From the project list itself you will be able to access each project by clicking on the item in the table. Once you have navigated to your project, you can go to Distribution > Direct Link/Embeber on my website and disable the links when you need to. This way your projects will no longer be public and will no longer consume data from your account.
