In the future, how do you plan to determine the value increase of just the project separate from the rest of the company?

Value increases will be determined by the next sale of tokens, or during trigger events.

And do I have a guarantee that the collected funds will only be used for the wallet project and not for the rest of the company?

Not entirely, but that's mainly because eventually all of the rest of our company will be rolled into this wallet. Most of the expense will be used to pay Wallet developer salaries, but some of our resources (like office and general brand marketing) are shared, so it would be difficult to keep completely separate. Sorry I can't give a more satisfactory answer.
