How does the automated App upgrade process works?

The majority of the Apps start with the required minimum 1 vCPU/RAM.

At all times you have complete control over the resources usage of your App by looking at the Stats Tabs in your account.

The
moment that your App starts to use above the assigned vCPU/RAM limit,
it will be upgraded automatically to the next level (so that it doesn't
stop working). That day we will automatically inform you via email about
this event. We will ask for your consent to upgrade the App to the next
package.

A. If you agree, the system will automatically perform the change.

B.
If you disagree, we will move the resource limits back to the original
package. In that case note that if you lower your usage, the App will
continue to perform as usual. But if you continue to increase the usage,
the App will automatically slow down & restart from time to time
due to the insufficient resources.

Note: We will never perform an upgrade and charge you for it without your explicit consent.
