-Element je inovatívny kolaboračný komunikátor a messenger ktorý:
+Element je zabezpečený messenger a zároveň aplikácia na tímovú spoluprácu, ktorá je ideálna na skupinové konverzácie pri práci na diaľku. Táto komunikačná aplikácia využíva end-to-end šifrovanie na poskytovanie výkonných videokonferencií, zdieľania súborov a hlasových hovorov.
 
-1. Ponecháva kontrolu nad vaším súkromím
-2. Umožňuje komunikovať s kýmkoľvek v sieti Matrix a vďaka integráciám aj s rôznymi inými aplikáciami ako napríklad Slack
-3. Chráni vás pred reklamami, zhromažďovaním údajov a uzavretými platformami
-4. Posilňuje vašu bezpečnosť vďaka E2E šifrovaniu a krížovému podpisovaniu určenému na overovanie ostatných
+<b>Funkcie aplikácie Element zahŕňajú:</b>
+- Pokročilé nástroje na online komunikáciu
+- Plne šifrované správy umožňujúce bezpečnejšiu firemnú komunikáciu aj pre pracovníkov na diaľku
+- Decentralizované konverzácie založené na open source frameworku Matrix
+- Bezpečné zdieľanie súborov so šifrovanými údajmi pri správe projektov
+- Videochaty s funkciou Voice over IP a zdieľaním obrazovky
+- Jednoduchá integrácia s obľúbenými nástrojmi na online spoluprácu, nástrojmi na riadenie projektov, službami VoIP a inými aplikáciami na tímovú komunikáciu
 
-Element sa od ostatných komunikačných a kolaboračných aplikácií odlišuje tým, že je decentralizovaný a open-source.
+Element sa úplne líši od ostatných aplikácií na zasielanie správ a spoluprácu. Funguje na Matrixe, otvorenej sieti na bezpečné posielanie správ a decentralizovanú komunikáciu. Umožňuje vlastný hosting, aby používatelia získali maximálne vlastníctvo a kontrolu nad svojimi údajmi a správami.
 
-S Elementom sa môžete pripojiť k vlastnému serveru alebo si môžete vybrať server s dôveryhodným poskytovateľom, čím si zachováte súkromie, vlastníctvo a kontrolu nad vašimi konverzáciami a údajmi. Získate tak prístup do otvorenej siete a teda nie ste limitovaní na komunikáciu len s ostatnými Element používateľmi. A samozrejme je vaša komunikácia dobre zabezpečná.
+<b>Súkromie a šifrovanie správ</b>
+Element vás chráni pred nežiaducimi reklamami, ťažbou údajov a tzv. walled gardens. Zabezpečuje tiež všetky vaše údaje, video a hlasovú komunikáciu jeden na jedného prostredníctvom end-to-end šifrovania a overovania zariadení krížovým podpisovaním
+Element vám poskytuje kontrolu nad vaším súkromím a zároveň vám umožňuje bezpečne komunikovať s kýmkoľvek v sieti Matrix alebo s inými nástrojmi na podnikovú spoluprácu vďaka integrácii s aplikáciami, ako je napríklad Slack.
 
-Element všetko toto dokáže vďaka tomu, že pracuje podľa protokolu Matrix - štandardu na otvorenú, decentralizovanú komunikáciu.
+<b>Element môže byť na vašom vlastnom serveri</b>.
+Aby ste mali väčšiu kontrolu nad svojimi citlivými údajmi a konverzáciami, Element môže byť na vašom vlastnom serveri alebo si môžete vybrať ľubovoľný hosting založený na systéme Matrix - štandarde pre decentralizovanú komunikáciu s otvoreným zdrojovým kódom. Element vám poskytuje súkromie, súlad s bezpečnostnými predpismi a flexibilitu integrácie.
 
-Element vám dáva kontrolu tým, že si samy vyberiete, ako budete spravovať (ang. host) vaše konverzácie. Priamo v aplikácii Element si môžete vybrať z rôznych spôsobov hostovania:
+<b>Vlastnite svoje údaje</b>
+Vy rozhodujete o tom, kde budú vaše údaje a správy uložené. Bez rizika ťažby údajov alebo prístupu tretích strán.
 
-1. Získajte účet zdarma na verejnom servery matrix.org od vývojárov protokolu Matrix alebo si vyberte z tísíce iných serverov hostovaných dobrovoľníkmi
-2. Hostujte si účet spustením vlastného servera použitím vlastného hardvéru
-3. Prihláste sa k účtu na vlastnom servery objednaním služieb na platforme Element Matrix Services
+Element vám dáva kontrolu rôznymi spôsobmi:
