Replace "subscription" with "membership"

I don't sell "subscriptions" but "memberships".

Anyone who knows how to replace the name site wide?

Thx in advance

Could you elaborate on that? Is it a subscription block or widget or what is it?

squarespace uses "subscription" everywhere ex. on "my account" page where users can manage payment options etc. here they write "subscription" and I cannot find a #blockid or anything to allow me to edit the name using CSS...
