Not associated with Ghost Call but my expectation is that they'd use the logs for debugging major bugs during the beta period. Kind of hard to identify and reproduce transient issues without those logs.
Every computer has logs. If you interact with a server, you can't avoid it. Until we have decentralized apps, trust on this is unavoidable.
ZRTP and the sign-up process means it will be hard to connect the little metadata they have, so they've narrowed down the amount they're trusted with by a large margin
Which is exactly my point. There shouldn't be anything for a 'server' to 'log'. If there is, then it's not anonymous, not 'secure' either depending on the definition you use, and it should not be advertised as such.
No. Wrong. I'm not affiliated but clearly they are keeping the logs around for 24h during the beta-testing of the service in order to troubleshoot any bugs founds. That would be a lot harder to do without logs.
But they're not claiming to offer anonymity during the beta period I imagine, once the service is out of beta then they claim their service to be secure and anonymous.
You're either splitting hairs or being uncharitable.
It doesn't matter. Even if they're not keeping logs, there is no way for you to confirm that they're not keeping logs. To them, you are not anonymous, simple as that.
