Keepass has a synchronization mechanism, maybe you can get it to work between your phone and your PC?

If the files to be synchronized are accessible via a protocol that KeePass supports by default (e.g. files on a local hard disk or a network share, FTP, HTTP, HTTPS, WebDAV, ..., see the page 'Loading/Saving From/To URL' for details), then no plugins/extensions are required.

If one of the files to be synchronized should be accessed via SCP, SFTP or FTPS, you need the IOProtocolExt plugin, which adds support for these protocols to KeePass.

If one of the files to be synchronized is stored in a cloud storage: for most cloud storages, there is an integration with the local file system available (i.e. you can access your stored files using Windows Explorer). For example, Dropbox, Microsoft OneDrive and Google Drive provide such an integration. If such an integration is available, it is recommended that you access your database file this way; this often works better than accessing it via a protocol like FTP or WebDAV. If no such integration is available and your cloud storage also is not accessible via a standard protocol, a specialized KeePass plugin for this cloud storage might be available.
