EXTRA SAFE: Encrypted Chat for Android

EXTRA SAFE — Private messaging, reimagined

EXTRA SAFE is a free Android app built to make private conversations straightforward and dependable. It uses strong encryption so that only the people you choose can read your messages, access shared files, or take part in voice calls.

Key capabilities

• GDPR-aligned design and strong focus on user anonymity and data protection
• Seamless use across several devices with a single EXTRA SAFE number
• Peer-to-peer voice calls and video conferences that avoid routing media through a central server
• Video meetings that support up to five people in a single call
• End-to-end encryption for chats, attachments, and audio communications
• Secure transfer of files (multiple formats supported) with a maximum size of 25 MB
• Message self-destruction with a configurable timer for ephemeral conversations
• Automatic clearing of chat logs according to user-defined retention rules

Private messages and ephemeral options

All conversations are protected end-to-end, meaning message contents are unreadable to anyone except the intended recipients. If you prefer temporary exchanges, set a countdown for messages to delete themselves automatically. You can also choose how long chat histories are kept and let the app purge them according to your preferences.

Secure file exchange

Send images, documents, and other file types securely. Transfers are encrypted from end to end and the app accepts individual files up to 25 MB, maintaining the same confidentiality as text messages.

Calls and group video

Make encrypted voice calls and join small video meetings without relying on a central media server — media can flow directly between devices for added privacy. Group video sessions support up to five participants, making it suitable for small team discussions or private catch-ups.

Cross-device use and identity

Use EXTRA SAFE across multiple devices tied to one EXTRA SAFE number for a consistent identity and synchronized access. This lets you move between devices without sacrificing privacy or losing message continuity.

Compliance and privacy guarantees

EXTRA SAFE is developed with GDPR principles in mind and emphasizes minimal data retention and user anonymity. The combination of end-to-end encryption, user-controlled deletion, and on-device handling of media helps reduce exposure of personal information while keeping communications private.
