Signal

Signal is a cross-platform encrypted messaging service developed by the Signal Foundation and Signal Messenger LLC, designed for individuals and groups who prioritize privacy and security. It enables users to send one-to-one and group messages over the Internet, including files, voice notes, images, and videos, making it ideal for confidential communication and sharing sensitive information while minimizing the risk of surveillance. Signal stands out for its strong encryption, open-source nature, and commitment to user privacy, with no ads or trackers. However, it may not offer as many features as some other messaging apps and has a smaller user base, which could limit connectivity with certain contacts.
