+ PeerTube uses the BitTorrent protocol to share bandwidth between users by default to help lower the load on the server,
+ but ultimately leaves you the choice to switch back to regular streaming exclusively from the server of the video. What
+ follows applies only if you want to keep using the P2P mode of PeerTube.
+ </p>
+
+ <p i18n>
+ The main threat to your privacy induced by BitTorrent lies in your IP address being stored in the instance's BitTorrent
+ tracker as long as you download or watch the video.
+ </p>
+
+ <h3 i18n class="p2p-privacy-title">What are the consequences?</h3>
+
+ <p i18n>
+ In theory, someone with enough technical skills could create a script that tracks which IP is downloading which video.
+ In practice, this is much more difficult because:
+ </p>
+
+ <ul>
+ <li i18n>
+ An HTTP request has to be sent on each tracker for each video to spy.
+ If we want to spy all PeerTube's videos, we have to send as many requests as there are videos (so potentially a lot)
+ </li>
+
+ <li i18n>
+ For each request sent, the tracker returns random peers at a limited number.
+ 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
+ requests sent to know every peer in the swarm
+ </li>
+
+ <li i18n>
+ Those requests have to be sent regularly to know who starts/stops watching a video. It is easy to detect that kind of behaviour
+ </li>
+
+ <li i18n>
+ 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
+ video
+ </li>
+
+ <li i18n>
+ The IP address is a vague information: usually, it regularly changes and can represent many persons or entities
+ </li>
+
+ <li i18n>
+ Web peers are not publicly accessible: because we use the websocket transport, the protocol is different from classic BitTorrent tracker.
+ When you are in a web browser, you send a signal containing your IP address to the tracker that will randomly choose other peers
+ to forward the information to.
+ See <a class="link-orange" href="https://github.com/yciabaud/webtorrent/blob/beps/bep_webrtc.rst">this document</a> for more information
+ </li>
+ </ul>
+
+ <p i18n>
+ The worst-case scenario of an average person spying on their friends is quite unlikely.
+ There are much more effective ways to get that kind of information.
+ </p>
+
+ <h3 i18n class="p2p-privacy-title">How does PeerTube compare with YouTube?</h3>
+
+ <p i18n>
+ The threats to privacy with YouTube are different from PeerTube's.
+ In YouTube's case, the platform gathers a huge amount of your personal information (not only your IP) to analyze them and track you.
+ Moreover, YouTube is owned by Google/Alphabet, a company that tracks you across many websites (via AdSense or Google Analytics).
+ </p>
+
+ <h3 i18n class="p2p-privacy-title">What can I do to limit the exposure of my IP address?</h3>
+
+ <p i18n>
+ 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
+ your IP in their connection logs: ISP/routers/trackers/CDN and more.
+ 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.
+ Thinking that removing P2P from PeerTube will give you back anonymity doesn't make sense.
+ </p>
+
+ <h3 i18n class="p2p-privacy-title">What will be done to mitigate this problem?</h3>
+
+ <p i18n>
+ PeerTube wants to deliver the best countermeasures possible, to give you more choice
+ and render attacks less likely. Here is what we put in place so far:
+ </p>
+
+ <ul>
+ <li i18n>We set a limit to the number of peers sent by the tracker</li>
+ <li i18n>We set a limit on the request frequency received by the tracker</li>
+ <li i18n>Allow instance admins to disable P2P from the administration interface</li>
+ </ul>
+
+ <p i18n>
+ Ultimately, remember you can always disable P2P by toggling it in the video player, or just by disabling
+ WebRTC in your browser.
