When users have persistent identities, even if this is just a random number, like a Session ID, there is a risk that the provider or an attacker can observe how the users are connected and how many messages they send.
</p>
<p>
They could then correlate this information with the existing public social networks, and determine some real identities.
</p>
<p>
Even with the most private apps that use Tor v3 services, if you talk to two different contacts via the same profile they can prove that they are connected to the same person.
</p>
<p>
SimpleX protects against these attacks by not having any user IDs in its design. And, if you use Incognito mode, you will have a different display name for each contact, avoiding any shared data between them.

<p>
Many users asked: <em>if SimpleX has no user identifiers, how can it know where to deliver messages?</em>
</p>
<p>
To deliver mesages, instead of user IDs used by all other platforms, SimpleX uses temporary anonymous pairwise identifiers of message queues, separate for each of your connections &mdash; there are no long term identifiers.
</p>
<p>
You define which server(s) to use to receive the messages, your contacts &mdash; the servers you use to send the messages to them. Every conversation is likely to use two different servers.
</p>
<p>
This design prevents leaking any users&apos; metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor.
</p>
<p>
Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer end-to-end encryption.

Many large companies use information about who you are connected with to estimate your income, sell you the products you don't really need, and to determine the prices.
</p>
<p>
Online retailers know that people with lower incomes are more likely to make urgent purchases, so they may charge higher prices or remove discounts.
</p>
<p>
Some financial and insurance companies use social graphs to determine interest rates and premiums. It often makes people with lower incomes pay more &mdash; it is known as <a href='https://fairbydesign.com/povertypremium/' target='_blank'>'poverty premium'</a>.
</p>
<p>
SimpleX platform protects the privacy of your connections better than any alternative, fully preventing your social graph becoming available to any companies or organizations. Even when people use servers provided by SimpleX Chat, we do not know the number of users or their connections.

Not so long ago we observed the major elections being manipulated by <a href='https://en.wikipedia.org/wiki/FacebookCambridge_Analytica_data_scandal' target='_blank'>a reputable consulting company</a> that used our social graphs to distort our view of the real world and manipulate our votes.
</p>
<p>
To be objective and to make independent decisions you need to be in control of your information space. It is only possible if you use private communication platform that does not have access to your social graph.
</p>
<p>
SimpleX is the first platform that doesn't have any user identifiers by design, in this way protecting your connections graph better than any known alternative.

Everyone should care about privacy and security of their communications &mdash; harmless conversations can put you in danger, even if you have nothing to hide.
</p>
<p>
One of the most shocking stories is the experience of <a href='https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi' target='_blank'>Mohamedou Ould Salahi</a> described in his memoir and shown in The Mauritanian movie. He was put into Guantanamo camp, without trial, and was tortured there for 15 years after a phone call to his relative in Afghanistan, under suspicion of being involved in 9/11 attacks, even though he lived in Germany for the previous 10 years.
</p>
<p>
Ordinary people get arrested for what they share online, even via their 'anonymous' accounts, <a href='https://www.dailymail.co.uk/news/article-11282263/Moment-police-swoop-house-devout-catholic-mother-malicious-online-posts.html' target='_blank'>even in democratic countries</a>.
</p>
<p>
It is not enough to use an end-to-end encrypted messenger, we all should use the messengers that protect the privacy of our personal networks &mdash; who we are connected with.

Unlike other messaging platforms, SimpleX has <strong>no identifiers assigned to the users</strong>. It does not rely on phone numbers, domain-based addresses (like email or XMPP), usernames, public keys or even random numbers to identify its users &mdash; we don&apos;t know how many people use our SimpleX servers.
</p>
<p>
To deliver messages SimpleX uses <a href='https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier'>pairwise anonymous addresses</a> of unidirectional message queues, separate for received and sent messages, usually via different servers. Using SimpleX is like having <strong>a different &ldquo;burner&rdquo; email or phone for each contact</strong>, and no hassle to manage them.
</p>
<p>
This design protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. To hide your IP address from the servers, you can <strong>connect to SimpleX servers via Tor</strong>.

SimpleX Chat stores all user data only on client devices using a <strong>portable encrypted database format</strong> that can be exported and transferred to any supported device.
</p>
<p>
The end-to-end encrypted messages are held temporarily on SimpleX relay servers until received, then they are permanently deleted.
</p>
<p>
Unlike federated networks servers (email, XMPP or Matrix), SimpleX servers don&apos;t store user accounts, they only relay messages, protecting the privacy of both parties.
</p>
<p>
There are no identifiers or ciphertext in common between sent and received server traffic &mdash; if anybody is observing it, they cannot easily determine who communicates with whom, even if TLS is compromised.

You can <strong>use SimpleX with your own servers</strong> and still communicate with people who use the pre-configured servers provided by us.

SimpleX platform uses an <a href='https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md' target='_blank'>open protocol</a> and provides <a href='https://github.com/simplex-chat/simplex-chat/tree/stable/packages/simplex-chat-client/typescript' target='_blank'>SDK to create chat bots</a>, allowing implementation of services that users can interact with via SimpleX Chat apps &mdash; we&apos;re really looking forward to see what SimpleX services you can build.

<a href='https://en.wikipedia.org/wiki/Peer-to-peer'>P2P</a> messaging protocols and apps have various problems that make them less reliable than SimpleX, more complex to analyse, and vulnerable to several types of attack.
</p>
<ol style="list-style: auto; padding-left: 1em;">
<li>
P2P networks rely on some variant of <a href='https://en.wikipedia.org/wiki/Distributed_hash_table'>DHT</a> to route messages. DHT designs have to balance delivery guarantee and latency. SimpleX has both better delivery guarantee and lower latency than P2P, because the message can be redundantly passed via several servers in parallel, using the servers chosen by the recipient. In P2P networks the message is passed through <em>O(log N)</em> nodes sequentially, using nodes chosen by the algorithm.
</li>
<li>
SimpleX design, unlike most P2P networks, has no global user identifiers of any kind, even temporary, and only uses temporary pairwise identifiers, providing better anonymity and metadata protection.
</li>
<li>
P2P does not solve <a href='https://en.wikipedia.org/wiki/Man-in-the-middle_attack'>MITM attack</a> problem, and most existing implementations do not use out-of-band messages for the initial key exchange. SimpleX uses out-of-band messages or, in some cases, pre-existing secure and trusted connections for the initial key exchange.
</li>
<li>
P2P implementations can be blocked by some Internet providers (like <a href='https://en.wikipedia.org/wiki/BitTorrent'>BitTorrent</a>). SimpleX is transport agnostic - it can work over standard web protocols, e.g. WebSockets.
</li>
<li>
All known P2P networks may be vulnerable to <a href='https://en.wikipedia.org/wiki/Sybil_attack'>Sybil attack</a>, because each node is discoverable, and the network operates as a whole. Known measures to mitigate it require either a centralized component or expensive <a href='https://en.wikipedia.org/wiki/Proof_of_work'>proof of work</a>. SimpleX network has no server discoverability, it is fragmented and operates as multiple isolated sub-networks, making network-wide attacks impossible.
</li>
<li>
P2P networks may be vulnerable to <a href='https://www.usenix.org/conference/woot15/workshop-program/presentation/p2p-file-sharing-hell-exploiting-bittorrent'>DRDoS attack</a>, when the clients can rebroadcast and amplify traffic, resulting in network-wide denial of service. SimpleX clients only relay traffic from known connection and cannot be used by an attacker to amplify the traffic in the whole network.
