Why Does Amazing Fields Need so Many Trello Permissions?
When you authorize Amazing Fields, you see a long list of permissions. This can look alarming, but the reality is that Trello does not support fine-grained authorization. Amazing Fields can only request read and write access in general, which includes access to things it does not actually use.

What Amazing Fields actually uses
Despite the broad permission list, Amazing Fields only uses authorization for three things:
- Reading and writing data to cards on the board you currently have open
- Reading and writing data to the currently open board
- Reading your account name to identify you as a user
Important: Amazing Fields does not access any of your data remotely. All permission use happens in your browser, for actions you are actively taking. Amazing Fields does not store any of your card data on external servers. All data remains on the Trello servers, under your control.
