Signal is one of the most popular messaging apps right now. While not the most feature-rich app like its rivals WhatsApp and Telegram, Signal is big on all things privacy. The app’s tagline for protecting user data has been leaked to a number of in-app features that offer users top-notch privacy that not many apps can offer.
While Signal’s end-to-end encryption for chats and calls is great, here are some more privacy-oriented features Signal has that you need to know about.
Proxy support in forbidden regions
Signal is one of the few messaging apps that supports proxy addresses. This allows Signal to be used through a proxy server in countries where the application is prohibited. Currently, this feature is for Android only. Signal also automatically sets up a proxy server when you tap on a link or scan a QR code. Even when using a proxy, your signal traffic remains opaque to the proxy operator.
Signal allows you to block screenshots in the application. This option, when enabled, does not allow your own phone to take screenshots of your chats. This ensures that your chats are safe from any other applications running at the same time, some of which could be malicious. Your Signal app also shows a black preview in the recent apps section when enabled. However, please note that this feature does not prevent your contacts from taking screenshots of your chat.
Signal’s incognito keyboard is not a separate keyboard itself, but rather a modified version of your existing keyboard app. When this option is enabled, your keyboard offers you complete privacy while in the application, without taking any data from what you type. However, this also means that your keyboard learning capabilities, real-time dictionary, and auto-correct functions may not work properly. That said, it’s still a great feature if data privacy on Signal is your main concern.
Signal’s call forwarding feature allows your calls to be relayed through the Signal server. Compared to normal token calls, this prevents your caller from obtaining your IP address. However, since the feature works by relaying your call through an additional server element, the quality of your call may suffer and you may not find the same clarity in your voice. So if call quality is your top priority, you can always
Signal also has SMS integration and can be your primary SMS application if you allow it. This would allow you to effectively use an application for chats and SMS conversations. However, you will lose the features that your standard messaging app offers, such as RCS support in Google Messages.
