<h3>How is Cwtch different to Signal / Whatsapp / iMessage?</h3>
<p>Cwtch is decentralized and focused on metadata-privacy in addition to communications privacy. Unlike other communication platforms,
none of your messages are routed through a centralized server that has access to metadata such as your social network of friends, or
who sent and received a particular message.
</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
designed Cwtch for metadata privacy. </p>

<p>Cwtch Groups allow multiple parties to participate in a single conversation using an untrusted server (that can be provided by 3rd party or
self hosted). Server operators cannot learn how many people are in a group, or what is being discussed. If multiple groups are hosted on a
single server then the server is unable to learn which messages belong to which group without the collusion of a group member. Unlike in peer-to-peer
conversations, group conversations can be conducted asynchronously, so everyone in a group doesn't need to be online at the same time.</p>
<h3>Why are cwtch groups experimental?</h3>
<p>Metadata-resistant group messaging is still an <a href="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>
<h3>What happens if I forget the password to an encrypted profile?</h3>
<p>Unlike a traditional centralized service that can offer password overrides, Cwtch stores all your data locally on your device.</p>
<p>Without the password it is practically impossible for anyone to derive the key to decrypt the profile. As such that profile should be considered
lost.</p>

<p>When a Tor process is running it will download some amount of data in order to retrieve consensus from the Tor network.
Any active onion services will also require a small amount of data to maintain their circuits and introduction points independent of any app use.</p>
<p>In the future we plan to allow cwtch clients to opt-in to using an external Tor connection such as Orbot to manage Tor processes
separately from Cwtch.</p>
<h3>How can I shutdown Cwtch?</h3>
<p>The front-pane of the app has a "Shutdown Cwtch" button (with an 'X') icon. Pressing this button will trigger a dialog, and on confirmation
Cwtch will be shutdown and all profiles will be unloaded.</p>
<h3>How can I get involved in supporting Cwtch?</h3>
