Can I safely delete HockeySDK application passwords from Keychain?

I'm trying to clear out years of accumulated crud from my Keychain, and I noticed that both Skype and Evernote have "HockeySDK" passwords saved. Evernote has 2 of them.

I checked the web, and it appears that HockeySDK is an application for reporting application errors. But I couldn't find any information about why it might need a password in my keychain.
