The app is encrypted end-to-end by default, but it can record metadata like the date, timestamp, and phone numbers associated with a message, according to a recently revised privacy policy. Unfortunately, you can't voice or video call from the web. There is a native desktop app, but it's essentially a portal to the web app. You can send and receive WhatsApp text messages from your mobile phone or the web. One of my favorite features is the ability to "star" messages with important reference information and access all of those starred messages in one, convenient place. Multimedia (like photos, videos, audio messages and files up to 100MB) are compressed automatically by the app, so they send quickly even when connection is poor. It has a simple, easy-to-understand interface, without the overwhelming bells and whistles of the Viber and Line apps. WhatsApp offers free text messaging, group messaging, voice, and video calls over cellular data or Wi-Fi. Plus, the Facebook-owned app has over one billion users on its platform, so it's likely that some of your friends already using it. It has a giant user base, is super fast, works on many different devices (even Blackberry!), has an easy-to-understand interface, and provides end-to-end encryption. WhatsApp (free, iOS, Android, Windows phone and web) is the Ultimate Messaging App.
