Aster Communications is a privacy-first company building an end-to-end encrypted communications suite for people who take their privacy seriously.

Our flagship product, Aster Mail, is an encrypted email client with post-quantum cryptography that works with any email provider. All encryption happens client-side, meaning we cannot read your emails by design. Zero-access architecture, fully open source under AGPL v3, and our servers are located in Germany.

We're building toward a full encrypted suite including Aster Drive, Aster Chat, and Aster Authenticator.
