Entwicklung, Wartung und Betrieb Signal kostet jedes Jahr zig Millionen Dollar. Wof\u00fcr wird dieses Geld ben\u00f6tigt?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Signal ist nicht auf Gewinn ausgerichtet<\/h2>\n\n\n\n<p>Zun\u00e4chst einmal ist es wichtig zu wissen, dass Signal eine gemeinn\u00fctzige Organisation ist. Das bedeutet Signal ist nicht auf Gewinn ausgerichtet, sondern wird ausschlie\u00dflich f\u00fcr die Benutzer erstellt. Es gibt keine Investoren oder Vorstandsmitglieder, die Gewinne fordern, sodass Signal sich voll und ganz auf den Datenschutz zu konzentrieren. Umsatzmodelle anderer Apps wie personalisierte Werbung und das Sammeln, Verwenden und Verkaufen von Nutzerdaten gehen immer auf Kosten der Privatsph\u00e4re der Nutzer. <a href=\"https:\/\/aboutsignal.com\/de\/blog\/wie-verdient-signal-geld-das-umsatzmodell-von-signal\/\">Im Gegensatz dazu ist die Haupteinnahmequelle von Signal die Spenden von Benutzern<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Signal kostet Dutzende Millionen Dollar pro Jahr<\/h2>\n\n\n\n<p>Die Entwicklung, Wartung und der Betrieb von Signal kostet j\u00e4hrlich mehrere zehn Millionen Dollar. Ab 2025 erwartet Signal, dass dieser Betrag j\u00e4hrlich auf bis zu 50 Millionen Dollar steigen wird. <a href=\"https:\/\/signal.org\/blog\/signal-is-expensive\/\">In einem ausf\u00fchrlichen Blogbeitrag<\/a>, erkl\u00e4rt Signal wohin dieses Geld flie\u00dft.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Infrastrukturkosten 14 Millionen Dollar pro Jahr<\/h2>\n\n\n\n<p>Damit Sie Signal nutzen k\u00f6nnen, ist nat\u00fcrlich Infrastruktur erforderlich. Dazu geh\u00f6ren die tempor\u00e4re Speicherung von Ende-zu-Ende-verschl\u00fcsselten Daten f\u00fcr die Nachrichten\u00fcbermittlung, ein globales Servernetzwerk, Registrierungskosten f\u00fcr Verifizierungscodes, Bandbreite und einige zus\u00e4tzliche Dienste.<\/p>\n\n\n\n<p>Die Kosten setzen sich wie folgt zusammen (Stand November 2023):<\/p>\n\n\n\n<p><strong>Speicherdienst: <\/strong>1,3 Millionen Dollar pro Jahr.<br><strong>Server:<\/strong> 2,9 Millionen Dollar pro Jahr.<br><strong>Anmeldekosten:<\/strong> 6,0 Millionen Dollar pro Jahr.<br><strong>Gesamtbandbreite: <\/strong>2,8 Millionen Dollar pro Jahr.<br><strong>Zus\u00e4tzliche Dienstleistungen:<\/strong> 700.000 Dollar pro Jahr.<\/p>\n\n\n\n<p>Zu den zus\u00e4tzlichen Dienstleistungen geh\u00f6ren Dinge wie die \u00dcberwachung der Betriebszeit, Ausfallwarnungen, Notfallkapazit\u00e4t und Wartungsvertr\u00e4ge.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Die Personalkosten betragen 19 Millionen Dollar pro Jahr<\/h2>\n\n\n\n<p>Ohne Personal w\u00e4re Signal nat\u00fcrlich nicht m\u00f6glich. Signal hat separate Teams f\u00fcr jede Plattform (Android, iOS und Desktop), die kontinuierlich daran arbeiten, dass Signal weiterentwickelt wird und stabil l\u00e4uft. Dazu geh\u00f6ren Systemaktualisierungen, die Entwicklung neuer Funktionen und die Sicherstellung, dass die App auf einer Vielzahl von Ger\u00e4ten funktioniert.<\/p>\n\n\n\n<p>Au\u00dferdem arbeitet ein Team von Entwicklern am <a href=\"https:\/\/github.com\/signalapp\/signal-server\">Signal Servercode<\/a> Servercodeund Bibliotheken wie <a href=\"https:\/\/github.com\/signalapp\/RingRTC\">RingRTC<\/a> und <a href=\"https:\/\/github.com\/signalapp\/libsignal\">libsignal<\/a>. Viele der Signal-Entwickler sind hochqualifizierte Spezialisten mit un\u00fcbertroffener Erfahrung und Fachkompetenz in den Bereichen Verschl\u00fcsselung, Sicherheit und Hochverf\u00fcgbarkeits-Apps. <\/p>\n\n\n\n<p>Dar\u00fcber hinaus legen Produkt- und Designteams die Funktionen und das Erscheinungsbild der App fest. Ein Lokalisierungsteam sorgt daf\u00fcr, dass die App in \u00fcber sechzig Sprachen verf\u00fcgbar ist.<\/p>\n\n\n\n<p>Schlie\u00dflich gibt es ein Vollzeit-Support-Team, das mit den Benutzern interagiert. Da Signal \u00fcber keine Analysefunktionen in der App verf\u00fcgt und keine Benutzerdaten sammelt, verl\u00e4sst es sich stark auf dieses Feedback.<\/p>\n\n\n\n<p>Derzeit besch\u00e4ftigt das Unternehmen etwa 50 Vollzeitbesch\u00e4ftigte, was im Vergleich zu anderen Apps sehr wenig ist. Beispielsweise besch\u00e4ftigt Line in Japan 3,100 Mitarbeiter und KakaoTalk 4,000. Gr\u00f6\u00dfere Unternehmen wie Apple, Meta (WhatsApp) und Google haben deutlich mehr Mitarbeiter.<\/p>\n\n\n\n<p>Ungef\u00e4hr die H\u00e4lfte von Signals Budget flie\u00dft in die Rekrutierung und Bindung von Mitarbeitern. Einschlie\u00dflich Geh\u00e4ltern, Sozialleistungen, Personaldienstleistungen, Personalbeschaffung und Steuern bel\u00e4uft sich dies auf rund 19 Millionen Dollar pro Jahr.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Forschungs- und Entwicklungskosten<\/h2>\n\n\n\n<p>Forschungs- und Entwicklungskosten sind die letzte Kategorie. Dazu geh\u00f6rt die teure, aber wichtige Forschung zur Verbesserung der Datenschutztechnologie, wie beispielsweise das j\u00fcngste Post-Quantum-Upgrade f\u00fcr das Signal Protokoll.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Unterst\u00fctzen Sie Signal indem Sie spenden<\/h2>\n\n\n\n<p>Alles in allem, entstehen Signal erhebliche Kosten um die App zu entwickeln und zu warten und einige dieser Kosten steigen mit jedem neuen Benutzer. Allerdings wurde Signal entwickelt, um Ihre Privatsph\u00e4re zu sch\u00fctzen. Signal folgt daher keinem Gesch\u00e4ftsmodell, das Ihr Verhalten verfolgt oder Ihre privaten Gespr\u00e4che kommerzialisiert, um diese Kosten zu decken.<\/p>\n\n\n\n<p>Stattdessen zielt Signal darauf ab zu beweisen, dass Apps wirklich ausschlie\u00dflich f\u00fcr Benutzer erstellt werden k\u00f6nnen \u2013 und nicht f\u00fcr Investoren, Datenhunger oder Profit.<\/p>\n\n\n\n<p>M\u00f6chten Sie einen Beitrag leisten?

This means Signal is not focused on making a profit but is created solely for you, the users. There are no investors or board members demanding profits, allowing Signal to fully focus on privacy. Revenue models from other apps such as personalized ads and collecting, using, and selling user data always come at the expense of user privacy. <a href=\"https:\/\/aboutsignal.com\/blog\/how-does-signal-make-money-the-revenue-model-of-signal\/\">Signal\u2019s main source of income is donations from users<\/a>.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">Signal costs tens of millions of dollars per year<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>Developing, maintaining, and operating Signal costs tens of millions of dollars per year. From 2025, Signal expects this amount to rise to as much as 50 million dollars annually. In <a href=\"https:\/\/signal.org\/blog\/signal-is-expensive\/\">a detailed blog post<\/a>, Signal explains for the first time where all this money goes.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">Infrastructure costs 14 million dollars per year<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>To allow you to use Signal, infrastructure is obviously required. This includes temporarily storing end-to-end encrypted data for message delivery, a global network of servers, registration costs for verification codes, bandwidth, and some additional services.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>The costs are as follows (situation as of November 2023):<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p><strong>Storage: <\/strong>1.3 million dollars per year.<br><strong>Servers:<\/strong> 2.9 million dollars per year.<br><strong>Registration costs:<\/strong> 6.0 million dollars per year.<br><strong>Total bandwidth: <\/strong>2.8 million dollars per year.<br><strong>Additional services:<\/strong> 700,000 dollars per year.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Additional services include things like monitoring uptime, outage alerts, emergency capacity, and maintenance contracts.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">Personnel costs are 19 million dollars per year<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>Signal obviously cannot exist without staff.

A localization team ensures the app is available in more than sixty languages.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Finally, there is a full-time support team that interacts with users. Since Signal has no analytics in the app and collects no other user data, it relies heavily on this feedback.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Currently, there are about 50 full-time employees, which is very small compared to other apps. For example, Line in Japan has 3,100 employees, and KakaoTalk has 4,000.
