Like I said in my other post, I don't use postman. Your HN post reads like they are doing this without your permission and secretly: akin to say, finding out that facebook records your microphone to sell you ads or whatever. This is what I am reacting to, that they are doing it without your permission.

So what actually is going on then, is that postman has a feature that you don't have to use, that you know about, that you know requires it stores request / response data, and it is doing just that.
