About this app

Session is a private messenger offering privacy, anonymity, and security. With end-to-end encryption, no phone numbers for sign-up, and decentralisation, Session is a messenger that truly keeps your messages private and secure.

Session uses a powerful decentralised network of servers to route your messages, making it impossible for anyone to leak or sell your data. And with Session’s private routing protocols, your messages are completely anonymous. No one ever knows who you’re talking to, what you’re saying, or even your IP address.

Privacy is the default when you use Session. Every message is encrypted, every time. We take your privacy seriously — Session gives you a safe, private place to chat with your friends, family, or anyone in the world.

• Fully anonymous account creation: No phone number or email is needed to create an Account ID
• Decentralised server network: No data breaches, no central point of failure
• No metadata logging: Session doesn't store, track, or log your messaging metadata
• IP address protection: Your IP address is protected using a specialised onion routing protocol
• Closed groups: Private, end-to-end encrypted group chats for up to 100 people
• Secure attachments: Share voice snippets, photos, and files with Session's secure encryption and privacy protections
• Free and open-source: Don’t take our word for it — check Session's code yourself

Session is free as in free speech, free as in free beer, and free of ads and trackers. Session is built and maintained by the Session Foundation, a Swiss-based foundation dedicated to advancing digital rights and innovation. Take back your online privacy today — download Session.

no notifications ever come through. on either side doesn't work on my android or my iphone.When you close the app, please fix. Edit to your reply. I do not use the app any longer .I used the fast mode and also set everything according to what i do know for my device to receive message notifications, also the app on ios had the same issue. Also the person I was chatting with also (android) never received notifications on their device until they opened the app.

Session was great until I got added to a group chat that was just posting child porn. I coule find no way to report that. I could get each individual person's ID and submit each to a tip line, but there's no way to link the full group, and no way to report them or the entire group on the app itself. I can block them and that's it. The app itself is fine. But the devs shouldn't allow something like that to go on on their app.

We're deeply sorry you encountered this disturbing content. Due to Session's decentralized design, groups cannot be centrally moderated or reported within the app. We appreciate you taking the time to report these users to the authorities. We are currently investigating additional measures to reduce the misuse of Session.

Everything was great until maybe almost two weeks ago. All of of sudden, it,session,stopped working. I'd have to close and go back,but it wouldn't restart right away. Kept shutting down. Once it got going it would go ok until I two or more chats going,then it would do it some more....stop running. Got frustrating. I'd clear my data,basically just start all over. Work very briefly then would stop running again. Just a few hours ago,I uninstalled the app, the installed it again,didn't help
