How/What is the best way to capture proprietary business logic and concealed from prying eyes in Monday.com?
Hi @vyhua - What kind of business logic? Automations? Sales activity? More details will help us point you in the right direction.
As a side note, you’ll get the most control over what people can see and access if you have an Enterprise account.
Hey @vyhua! Agree with what @PolishedGeek said 
Another way to go to keep information private is Private Boards (available on the Pro plan and up).
Feel free to elaborate more on the kinds of information you’re looking to store and I’d be happy to offer suggestions!
Hi @TRB-monday.com and @PolishedGeek,
Business logic such as pricing or predictive algorithms. I would like to put it in a black box and make that black box available to teams (metaphorically)?
Hi @vyhua - Perhaps using General Caster would be suitable in this case? You can put all of the calculations in the app and just have the results pushed back into your boards.
