eBuddy Messenger for Android sending some strange arguments via HTTP

If you sniff your eBuddy Messenger connection, you might see something like this:

{
"adspace":{
"browser":"app",
"height":{
"min":1,
"optional":"true",
"max":1205
},
"width":{
"min":1,
"optional":"true",
"max":800
},
"close":"false",
"align":"center"
},
"response":{
"template":"mraid",
"type":"json",
"version":1
},
"versions":{
"platf orm":"android",
"sdk":"3.0.17"
},
"device":{
"screen":{
"orientation":"portrait",
"height":1205.0,
"width":800.0
},
"connection":"wifi",
"model":"Nexus 7",
"useragent":"Mozilla/5.0 (Linux; U; Android 4.3; de-de; Nexus 7 Build/JWR66Y) AppleWebKit/53 4.30 (KHTML, like Gecko) Version/4.0 Safari/534.30",
"location":{
}
},
"ad":{
"type":"live",
"format":"inline"
},
"user":{
"gender":"male",
"ids":{
"openid":"7de1d4ee699f6b3f"
},
"age":"21"
},
"channel":{
"id":"12345",
"type":"app"
},
"zone":{
"id":"7344452 053",
"secret":"F72ED7F54456407C"
}
}

Anyone any idea if they might use OpenID internally or what this data represents?
