960 Daily Chess rules clarification

I'd like to know if one can use computer analysis to find ideas before a match had started (locked/started).

https://support.chess.com/customer/en/portal/articles/1444879-fair-play-on-chess-com-what-you-need-to-know

does the term "game-in-progress" include the moment when you see the start position and the match hasn't been started?

No. When the game has started it has started.

But feel free to analyse all 960 starting positions before or after :)

yep computer analysis is allowed for opening ideas, answer from chess.com:
