<divclass="col-md-4 text-center"><strong>Decentralized and Open</strong><br/><p>Participants in Cwtch can host their own safe spaces, or lend their infrastructure to others
seeking a safe space. There is no “Cwtch service” or “Cwtch network”. The Cwtch protocol is <ahref="https://git.openprivacy.ca/cwtch.im/cwtch">open</a>, and anyone is free to <ahref="https://git.openprivacy.ca/sarah/cwtchbot">build bots, services</a> and <ahref="https://git.openprivacy.ca/cwtch.im/cwtch-ui">user interfaces</a>
and integrate and interact with Cwtch.</p></div>
<divclass="col-md-4 text-center"><strong>Privacy Preserving</strong><br/><p>All communication in Cwtch is end-to-end encrypted and takes place over Tor v3 onion services.</p></div>
<divclass="col-md-4 text-center"><strong>Metadata Resistant</strong><br/><p>Cwtch has been <ahref="https://docs.openprivacy.ca/cwtch-security-handbook/risk.html">designed</a> such that no information is exchanged or available to anyone without their explicit consent, including on-the-wire messages and protocol metadata.</p></div>
<pclass="card-text">They need access to metadata about your activities such as who you talk to, when and how much in order to offer features like group messaging and offline delivery.</p>
<pclass="card-text">Like other systems, Cwtch uses end to end encryption.
but the journey its messages take is different. Cwtch is a decentralized peer to peer platform built on Tor onion services.
With no need for a centralized server to route messages through, and onion routing provided by Tor, Cwtch establishes direct connections between peers while minimizing and sometimes even eliminating the metadata that 3rd parties can see.</p>
Cwtch uses cryptographic identifiers that anyone can anonymously generate for themselves as many times as they want. This means they can't be tied to your real world identity by anyone but you.</p>
<pclass="card-text">Cwtch is designed to put consent first. This means we never want the app to do something you don't expect or want. Cwtch gives more control over what information is shared, how and who can communicate with who. We'll never included unsolicited content such as advertising or trends.</p>
<p> We believe that our tools should help people resist surveillance. Communications metadata is known to be exploited by many adversaries to undermine the security of systems; to track people;
and to conduct large scale social networking analysis that feeds into mass surveillance systems. And because of that, we explicitly
<p>Metadata-resistant group messaging is still an <ahref="https://docs.openprivacy.ca/cwtch-security-handbook/open-questions.html">open problem</a>. While the version we provide in Cwtch Beta is designed to be secure and metadata
private it is rather inefficient and can be misused. As such we advise caution when using it, and only provide it as an opt-in feature.</p>
<p>Without the password, and the encrypted file, it is practically impossible for anyone to derive the key to decrypt the profile. As such that profile should be considered
<p>The reference implementation for a Cwtch server <ahref="https://git.openprivacy.ca/cwtch.im/server">is open source</a>. Anyone
can run a Cwtch server, and anyone with a copy of the <ahref="https://docs.openprivacy.ca/cwtch-security-handbook/key_bundles.html">server key bundle</a> of public keys can host groups on that server

every time the app is loaded which would make it slow to start, and would make peer connection unusable on Android, as everytime the app went away you would go offline.</p>
