At the moment we don’t offer feedly for Windows phones. But here are a couple of things that might interest you:
- You can access feedly from NextGen, a Windows Phone and Windows 8 app. See more here: http://www.feedly.com/apps.html
- feedly is available pure web (plugin and extension-free) and can be used on Windows as a result. Try here: http://cloud.feedly.com/
Adding Google Drive as an option to back-up your feeds (the same way we currently support via Dropbox) is something we are looking into.

Seems if you're going to do one, it would be best to make sure all of the big 4 are supported - Google Drive, OneDrive, iCloud - in addition to the current DropBox support.
