-1. Vám dá moc zachovat si soukromí
-2. Vás nechá komunikovat s kýmkoli v síti Matrix a dokonce dále integrací s aplikacemi jako Slack
-3. Vás ochrání před inzercí, těžbou dat a uzavřenými zahradami
-4. Vás zabezpečí šifrováním end-to-end s křížovým podepisováním pro ověření ostatních
+1. Vám dá kontrolu nad ochranou vašeho soukromí
+2. Umožní vám komunikovat s kýmkoli v síti Matrix a dokonce i mimo ni pomocí integrací s aplikacemi, jako je Slack
+3. Ochrání vás před inzercí, dataminingem a uzavřenými zahradami
+4. Zabezpečí vás end-to-end šifrováním s křížovým podpisem pro ověření ostatních
 
-Element is completely different from other messaging and collaboration apps because it is decentralised and open source.
+Element je zcela odlišný od ostatních aplikací pro zasílání zpráv a spolupráci, protože je decentralizovaný a otevřený.
 
-Element lets you self-host - or choose a host - so that you have privacy, ownership and control of your data and conversations. It gives you access to an open network; so you’re not just stuck speaking to other Element users only. And it is very secure.
+Element vám umožňuje použít vlastní domovský server - nebo si vybrat hostitele - abyste měli soukromí, vlastnictví a kontrolu nad svými daty a konverzacemi. Poskytuje vám přístup k otevřené síti; takže nejste zaseknuti jen při konverzaci s ostatními uživateli Elementu. A je velmi bezpečný.
 
-Element is able to do all this because it operates on Matrix - the standard for open, decentralised communication.
+Element je toho všeho schopen, protože pracuje na Matrixu - standardu otevřené, decentralizované komunikace.
 
-Element puts you in control by letting you choose who hosts your conversations. From the Element app, you can choose to host in different ways:
+Element vám dává kontrolu nad tím, že si můžete vybrat, kdo bude hostovat vaše konverzace. Z aplikace Element si můžete vybrat hostování různými způsoby:
 
-1. Get a free account on the matrix.org public server hosted by the Matrix developers, or choose from thousands of public servers hosted by volunteers
-2. Self-host your account by running a server on your own hardware
-3. Sign up for an account on a custom server by simply subscribing to the Element Matrix Services hosting platform
+1. Získejte zdarma účet na veřejném serveru matrix.org hostovaném vývojáři Matrixu, nebo si vyberte z tisíců veřejných serverů hostovaných dobrovolníky
+2. Hostujte svůj účet spuštěním serveru na svém vlastním hardwaru
+3. Zaregistrujte si účet na vlastním serveru jednoduchým přihlášením k hostitelské platformě Element Matrix Services
 
-<b>Why choose Element?</b>
+<b>Proč zvolit Element?</b>
 
-<b>OWN YOUR DATA</b>: You decide where to keep your data and messages. You own it and control it, not some MEGACORP that mines your data or gives access to third parties.
+<b>VLASTNĚTE SVÁ DATA</b>: Vy rozhodnete, kde svá data a zprávy ponecháte. Vlastníte je a jsou pod vaší kontrolou, ne nějaký MEGACORP, který těží vaše data nebo poskytuje přístup třetím stranám.
 
-<b>OPEN MESSAGING AND COLLABORATION</b>: You can chat with anyone else in the Matrix network, whether they’re using Element or another Matrix app, and even if they are using a different messaging system of the likes of Slack, IRC or XMPP.
+<b>ZPRÁVY A SPOLUPRÁCE</b>: Můžete chatovat s kýmkoli v síti Matrix, ať už používá Element nebo jinou aplikaci, a to i v případě, že používají jiný systém zasílání zpráv, jako je Slack, IRC nebo XMPP.
 
-<b>SUPER-SECURE</b>: Real end-to-end encryption (only those in the conversation can decrypt messages), and cross-signing to verify the devices of conversation participants.
+<b>MAXIMÁLNĚ BEZPEČNÉ</b>: Skutečné šifrování typu end-to-end (pouze ti v konverzaci mohou dešifrovat zprávy) a křížové podepisování k ověření zařízení účastníků konverzace.
 
-<b>COMPLETE COMMUNICATION</b>: Messaging, voice and video calls, file sharing, screen sharing and a whole bunch of integrations, bots and widgets. Build rooms, communities, stay in touch and get things done.
+<b>KOMPLETNÍ KOMUNIKACE</b>: Zprávy, hlasové hovory a videohovory, sdílení souborů, sdílení obrazovky a celá řada integrací, robotů a widgetů. Budujte místnosti, komunity, zůstaňte v kontaktu a spolupracujte.
 
-<b>EVERYWHERE YOU ARE</b>: Stay in touch wherever you are with fully synchronised message history across all your devices and on the web at https://app.element.io.
+<b>KDEKOLIV JSTE</b>: Zůstaňte v kontaktu, ať jste kdekoli, s plně synchronizovanou historií zpráv na všech vašich zařízeních a na webu na adrese https://app.element.io.
