There is no version of Codebook for Linux and it doesn’t appear to be changing.
In order to support Linux users, can you add a WebDAV sync feature?
Perhaps make it an in-app-purchase for the mobile app? I’d be willing to pay another $5 for that.
WebDAV could be useful for some non-Linux users as well…
When I originally bought Codepage (it was STRIP back then), it was the only password manager for iOS that was open source (if only partial).
Now, it’s just one of many open source password manager apps (some of them free) and it no longer fills my needs. It’s very disappointing that you are unwilling to do a Linux port and add a network sync option that does not use a 3rd party cloud provider (I and others asked for both years ago on the old forums already).
Such are the issues we face when we choose software that is not open source (only a small part of Codepage is open source).
