Silvra – Messenger

SILVRA

About this app

Silvra is a messenger from Europe. No ad network, no data brokers, no profiling —
an app for writing, calling and sharing.

ENCRYPTION THAT STILL HOLDS TOMORROW

Text messages in one-to-one and group chats are end-to-end encrypted. Silvra uses MLS
(Messaging Layer Security, RFC 9420) — the standard the Internet Engineering Task Force
built for the next generation of secure messengers.

What sets Silvra apart: it combines classical cryptography with a post-quantum method
(ML-KEM, the new NIST standard). Encrypted messages captured today cannot be read later,
even once powerful quantum computers exist. Whatever you write in confidence today stays
protected against an attacker with tomorrow's hardware.

Your keys never leave your devices. Silvra cannot read your messages — not even on
official request, because there is simply nothing readable to hand over.

WHAT YOU GET

• One-to-one and group chats with photos, voice messages, files and locations
• Voice and video calls
• Disappearing messages after an hour, a day or a week
• A feed for photos and videos, visible only to people you actually chat with
• Groups with polls, events and roles
• An optional points account — there if you want it, invisible if you don't

EUROPEAN, NOT JUST ON PAPER

Silvra is built and operated in Europe. Your data stays here, not in some other
jurisdiction. No ad tracking, no sharing with third parties, no analysis of your content —
there is nothing to analyse.

You sign in with your email address. No phone number, no password: you get a six-digit
code and you are in.

Silvra is available in English and German.
