[Q] Lost some contact, where are they?

I use a programme called VAULT where i can save lots of private number ect.
i recently installed a new rom, so before i did that i went into vault and it asked me do i want to save all numbers to phone and remove them from vault. i said yes and then went ahead and cleared data ect.
now on the new rom, i cant find these contacts.
where will the be?
their not on my phone list?
