Private-first is not the same as secretive

A private-first conversation is not a hidden one. It is a conversation where each person gets to think before they perform.
Prevow holds your answer until your partner has finished theirs. Nothing is graded. Nothing is ranked. The app does not tell you whether you passed.
Why that matters before marriage
The subjects in the programme are not trick questions. They are the ones people postpone because the wedding feels more urgent than the conversation. Private-first makes the conversation possible without turning it into a debate about who said what first.
