How to set restrictions on editing cards and deleting attachments from cards?

[Оксана Кузнецова]

There are restrictions and deleting desks. But what about it attachments? I want my colleges to have a possibility to watch it but not to change or delete it.

@Оксана Кузнецова When someone is a member of a board, they have the ability to edit/delete all cards on the board. There are no granular permissions for board members.

If it's a board in a Business Class team, you could potentially designate some users as Observers.

Observers are board members that are able to view a board and the cards within the board, download card attachments, comment and vote on cards if that is enabled for the board, and export the board.

Observers are not able to move or edit cards, upload card attachments and observers can't change board settings.
