No, iPassword did not save passwords in the cloud. Most other password apps do, including the built-in Keychain app. I think someone posted that they were able to extract the passwords from a computer backup of their phone using iMazing.

Use the forum Search (at the top of this page) to look for other posts about iPassword; there were several useful suggestions posted. When you use Search you can click on Filters and limit the search to recent posts.
