  75         PeerTube uses the BitTorrent protocol to share bandwidth between users by default to help lower the load on the server,
  76         but ultimately leaves you the choice to switch back to regular streaming exclusively from the server of the video. What
  77         follows applies only if you want to keep using the P2P mode of PeerTube.
  78       </p>
  79
  80       <p i18n>
  81         The main threat to your privacy induced by BitTorrent lies in your IP address being stored in the instance's BitTorrent
  82         tracker as long as you download or watch the video.
  83       </p>
  84
  85       <h3 i18n class="p2p-privacy-title">What are the consequences?</h3>
  86
  87       <p i18n>
  88         In theory, someone with enough technical skills could create a script that tracks which IP is downloading which video.
  89         In practice, this is much more difficult because:
  90       </p>
  91
  92       <ul>
  93         <li i18n>
  94           An HTTP request has to be sent on each tracker for each video to spy.
  95           If we want to spy all PeerTube's videos, we have to send as many requests as there are videos (so potentially a lot)
  96         </li>
  97
  98         <li i18n>
  99           For each request sent, the tracker returns random peers at a limited number.
 100           For instance, if there are 1000 peers in the swarm and the tracker sends only 20 peers for each request, there must be at least 50
 101           requests sent to know every peer in the swarm
 102         </li>
 103
 104         <li i18n>
 105           Those requests have to be sent regularly to know who starts/stops watching a video. It is easy to detect that kind of behaviour
 106         </li>
 107
 108         <li i18n>
 109           If an IP address is stored in the tracker, it doesn't mean that the person behind the IP (if this person exists) has watched the
 110           video
 111         </li>
 112
 113         <li i18n>
 114           The IP address is a vague information: usually, it regularly changes and can represent many persons or entities
 115         </li>
 116
 117         <li i18n>
 118           Web peers are not publicly accessible: because we use the websocket transport, the protocol is different from classic BitTorrent tracker.
 119           When you are in a web browser, you send a signal containing your IP address to the tracker that will randomly choose other peers
 120           to forward the information to.
 121           See <a href="https://github.com/yciabaud/webtorrent/blob/beps/bep_webrtc.rst">this document</a> for more information
 122         </li>
 123       </ul>
 124
 125       <p i18n>
 126         The worst-case scenario of an average person spying on their friends is quite unlikely.
 127         There are much more effective ways to get that kind of information.
 128       </p>
 129
 130       <h3 i18n class="p2p-privacy-title">How does PeerTube compare with YouTube?</h3>
 131
 132       <p i18n>
 133         The threats to privacy with YouTube are different from PeerTube's.
 134         In YouTube's case, the platform gathers a huge amount of your personal information (not only your IP) to analyze them and track you.
 135         Moreover, YouTube is owned by Google/Alphabet, a company that tracks you across many websites (via AdSense or Google Analytics).
 136       </p>
 137
 138       <h3 i18n class="p2p-privacy-title">What can I do to limit the exposure of my IP address?</h3>
 139
 140       <p i18n>
 141         Your IP address is public so every time you consult a website, there is a number of actors (in addition to the final website) seeing
 142         your IP in their connection logs: ISP/routers/trackers/CDN and more.
 143         PeerTube is transparent about it: we warn you that if you want to keep your IP private, you must use a VPN or Tor Browser.
 144         Thinking that removing P2P from PeerTube will give you back anonymity doesn't make sense.
 145       </p>
 146
 147       <h3 i18n class="p2p-privacy-title">What will be done to mitigate this problem?</h3>
 148
 149       <p i18n>
 150         PeerTube wants to deliver the best countermeasures possible, to give you more choice
 151         and render attacks less likely. Here is what we put in place so far:
 152       </p>
 153
 154       <ul>
 155         <li i18n>We set a limit to the number of peers sent by the tracker</li>
 156         <li i18n>We set a limit on the request frequency received by the tracker</li>
 157         <li i18n>Allow instance admins to disable P2P from the administration interface</li>
 158       </ul>
 159
 160       <p i18n>
 161         Ultimately, remember you can always disable P2P by toggling it in the video player, or just by disabling
 162         WebRTC in your browser.
