This is the universal build of Session - Private Messenger 1.21.3. It contains native libraries for every CPU architecture (arm64-v8a, armeabi-v7a, x86, x86_64), so it installs on any Android device. The trade-off is size — it's larger than per-architecture variants. Pick this one if you're unsure which CPU your phone has, or if you plan to share the APK with multiple devices.

App Description

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 OPTF, Australia’s first privacy tech not-for-profit organisation. Take back your online privacy today — download Session.

Frequently Asked Questions about Session - Private Messenger APK

This is the universal variant — a single APK that contains native libraries for every CPU architecture. It installs on any Android device but is larger than per-architecture variants.

Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.

Android 26 (API level 34) or newer. Older devices will refuse the install.

Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.

All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
