I Tried Signal, The Edward Snowden-Approved Messaging App, And I Actually Do Feel Safer

Signal operates without leaving your metadata behind-like your location, or information about the recipient of your messages. Your conversations are further protected as Signal uses an algorithm they’re calling the “double ratchet” to ensure that if someone does hack into an encrypted message, they won’t be able to crack all your past messages, as each of your messages uses a totally different encryption key, even when you send several messages in a row to the same user.
