Session is a private messaging app that uses a network of decentralized servers around the world to protect user data and privacy. It has several features that ensure anonymity and security, such as the ability to create an account without providing a phone number or email, a decentralized server network that prevents data breaches and central points of failure, no logging of messaging metadata, protection of IP addresses, and end-to-end encrypted group chats for up to 100 people. Session also allows users to securely share voice snippets, photos, and files. It is free to use and is open source, meaning that the code can be examined by anyone. Session is developed and maintained by the OPTF, a not-for-profit organization based in Australia that focuses on privacy technology. It is free of ads and trackers.
