WhatsApp versus Signal: Privacy policies, data collection and more
The app has been endorsed by personalities like Tesla and SpaceX CEO Elon Musk, American whistleblower Edward Snowden, Twitter CEO Jack Dorsey and Oscar-winning filmmaker and journalist Laura Poitras.
Here’s a comparison between the two most popular messaging apps:
1. WhatsApp is currently the largest messaging service in the world with more than 2 billion monthly active users, while Signal has around 20 million monthly active users.
2. WhatsApp recently introduced the new in-app payments feature. Group chats work with up to 256 members. One can broadcast messages to multiple contacts, support voice and video calls, both for individuals and groups. Whereas, Signal offers secure messaging, voice, and video calls with end-to-end encryption. One can create groups, but can’t broadcast messages to multiple contacts at once. Signal also has added support for group calling.
4. Unlike WhatsApp, Signal has the option to write a 'note to self' rather than forming a single person group to send notes to oneself.
5. Signal also collects much fewer user data compared to WhatsApp. While WhatsApp collects a huge pile of data including device ID, user ID, phone number, email address, contacts, advertising data and payment information, Signal only collects users' phone numbers.
