Why Vidar?
Many popular messaging apps require internet access, rely on centralized servers, and collect metadata. Vidar takes a different approach: it works entirely over SMS. As long as you have cellular signal, you can communicate without needing Wi-Fi or mobile data.
Vidar aims to give users stronger control over their privacy by reducing dependency on external infrastructure. This makes it useful in situations where internet access is limited — or when you simply want a minimal, private communication channel.
Privacy Note
Vidar is built to improve privacy, but no tool can guarantee “perfect anonymity.” Always keep your device secure, use strong lock-screen protection, and update apps regularly.
Key Features (At a Glance)
- Encrypted messaging over SMS (no internet required)
- No centralized servers to route your conversations
- Open-source codebase for transparency and community review

Security Reminder
Only install APKs from trusted sources. If Android warns about “unknown sources,” review the source carefully and avoid random mirrors.
