+		Notesnook is a free (as in speech) and open-source note-taking app focused on user privacy and ease of use.
+		To ensure zero knowledge principles, Notesnook encrypts everything on your device using XChaCha20-Poly1305 and Argon2.
+		Notesnook is our proof that privacy does not (always) have to come at the cost of convenience.
+		We aim to provide users peace of mind and 100% confidence that their notes are safe and secure.
+		The decision to go fully open source is one of the most crucial steps towards that.
