I noticed that qBittorrent has in "Tools" a "Manage cookies..." section. In it, one finds the cookies stored.

My questions are:

  1. What are these cookies for?
  2. Who stored them there (that is, how and why were they created)?
  3. Can I delete them or will I lose some sort of bittorrent traffic/functionality?
  4. Do these cookies pose any kind of privacy threat?


EDIT: I forgot to mention, I already read the FAQ, but, contrary to what it says, I never set any cookies (and even though I delete them, they keep reappering), nor have I ever used or enabled in the settings the RSS feed. I do think the cookies come from the trackers (one comes from FOSSHub, due to qBittorrent, I presume), but there are others like .google.com that I cannot imagine where they come from.

Is it possible to ban/disable the cookies functionality all together?

EDIT2: Is it possible that I'm suffering from a browser vulnerability that installs cookies when I click on certain links, as if they were magnet links?

    I believe that they are for authenticated trackers. its been a long time since I used one, but you used to have to occasionally browse to a site and login before you could connect to their tracker. – Frank Thomas Nov 28 '17 at 3:38

    Thanks for the comment! I think you maybe right, since most cookies are from trackers' domains. But where does the .google.com cookie come from? I have no torrent with such tracker, I think – flen Dec 2 '17 at 21:02
  • +1 Do you already have an answer for this question? – VMMF Feb 18 '19 at 5:14
  • @VMMF unfortunately, no. I manually delete them everytime – flen Mar 16 '19 at 18:42
