Signal offers modern messaging features with a focus on privacy. If you're concerned about messaging apps run by major corporations using your data for marketing or advertising purposes, Signal may be the app you're looking for. Signal makes use of advanced encryption signals on both ends of your exchanges, so you won't have to worry about your data going anywhere, and your messages are never stored on Signal's remote servers, so there's no need to fret about compromises to the security on their back end. Signal is also open source, so you can inspect the technology behind it yourself. This honest and straightforward approach to how their messenger works allows them to peer review their protocol and adapt more effectively to any potential insecurities.

While Signal puts a focus on privacy, that doesn't mean they've cut corners where functionality is concerned. You'll find most of the modern features you can expect in a current messaging app on Signal. Both one on one and group messaging is supported in Signal, and Signal doesn't have access to any of the information displayed in your groups. Your Signal account is tied in to your cell phone number and contact list, so you don't need to worry about maintaining the privacy of your account.
