Say it the way you'd tell someone in the office: "never put my suppliers' names on anything a customer sees. Make that a permanent rule." Mucka saves it and keeps to it from the next call or chat on, for everyone on your team.
Only the business owner can set or drop a rule. You can hold up to twenty, of up to 200 characters each.
Seeing and dropping them
Ask "what rules have you got?" and Mucka reads them out. "Forget the supplier one" drops it.
What a rule can and can't do
A rule tells Mucka how you want the work done. It changes nothing about who can see what, and if you ask for something different in the moment, Mucka does what you've asked and mentions the rule.
It governs what Mucka writes and books when you ask it to. It doesn't change anything you've already sent, or what the app does by itself, such as automatic reminders.
Rules that are about you, not the business
"Keep it to one line" or "call me Sam" is how Mucka talks to you, and it's saved for you alone. How the business words its messages to customers has its own setting: Settings, then Customers, then Automatic messages.
