Session - Private Messenger for iPhone

Quick summary

Session is a decentralized messaging app designed to protect user identity and keep conversations private. Instead of relying on a single central server, the service runs over a distributed network of user-operated nodes, reducing the risk of centralized data leaks or sales.

How anonymity is maintained

• Messages are routed using privacy-focused protocols so that senders and recipients remain unknown to outside observers.
• There is no central repository that can collect or monetize user data, because the network is operated across many independent servers.
• Users don’t need to provide a phone number or email to create an account, allowing truly anonymous signups.
• The app avoids storing or logging messaging metadata, limiting what can be traced or analyzed.

Main features

• Open-source codebase and free to use.
• End-to-end encrypted group chats supporting up to 100 participants.
• Secure sharing of attachments and files.
• Options to create fully anonymous accounts without linking personal contact details.
• Minimal metadata retention to preserve user privacy.

Who should consider it

• Privacy-first users who want strong anonymity without supplying phone numbers or emails.
• Groups or communities needing encrypted group conversations with secure file transfers.
• Anyone who prefers open-source tools so they can inspect or verify the software’s privacy claims.
