WhatPulse keeps asking permission to access Keychain

I am using WhatPulse on my mac with OS X 10.11 beta and WhatPulse keeps asking permission to access the password for my WiFi. I have found out that it usually asks I get connected a network, but not always. Even though I click “Allow always”, the permission still gets asked over and over. Is this a bug or normal behaviour? Why does WhatPulse need my WiFi password anyway?
