A few comments:
1. For several apps, you list https://github.com/site/privacy as the privacy policy.
I might be missing something, but I cannot find why the privacy policy of the programs whose code is hosted on github would have to adhere to the same policy.
2. Even if that is the case, I cannot find any reference to k-@ being hosted on github.
3. The empty website for K-@ has a note "we are in the process of setting up a new website" and it is dated Friday, 26 February 2016 16:28 (it's been over half a year):
http://www.1gravity.com/
I don't know what has been happening with it (so, I don't want to judge them, especially, since I see a rather strange "We are volunteers" on that website, even though 1gravity was listed as an LLC on its previous site [as seen on Archive.org: https://web.archive.org/web/20160109053252/http://1gravity.com/ ]).
But it is not a very good sign.
And, obviously, there is no privacy policy to be found on non-existing website.
