Description

Aster Mail is a complimentary, open-source email service that offers end-to-end encryption for users seeking genuine privacy without cumbersome technical requirements. The encryption process occurs directly on your device, ensuring that our servers never have access to your messages or any associated metadata. Utilizing the widely accepted OpenPGP standard with RSA-4096 keys, Aster ensures that you are not bound to a single provider; your keys can be used seamlessly with GPG, Thunderbird, or any compatible PGP client, and they are easily discoverable via WKD and public key servers. For communications between Aster users, the service employs a Signal-inspired X3DH and Double Ratchet protocol, providing enhanced forward secrecy. Each subscription tier comes with encrypted email capabilities, support for custom domains, free aliases, protection against trackers, and unrestricted access across both web and desktop platforms. The complete codebase is available under the AGPL v3 license on GitHub, allowing for thorough audits, and it features a public warrant canary along with a clear vulnerability disclosure policy. The free tier provides 10 GB of encrypted storage, along with 5 aliases and 1 custom domain. Paid subscriptions begin at just $2.99 per month, and all servers are conveniently located in Germany, ensuring compliance with stringent data protection regulations. Users can feel secure knowing their communications are protected by top-notch encryption standards.

Description

Our email hosting service offers top-tier encryption for your communications, employing zero-access encryption methods such as AES-GCM-256 combined with RSA-OAEP-4096 for key sharing, ensuring that only you can access your email contents while we cannot retrieve them at any point. Every aspect of your email experience is safeguarded, including subjects, headers, message bodies, attachments, drafts, and even push notifications. Based in Austria, we are dedicated to exceptional data security and harness Swiss infrastructure, which allows us to operate under some of the strongest privacy laws globally, especially in contrast to many US tech firms. When you sign up, you receive an initial 25 GB of storage, with an additional 2 GB added to your account every year, ensuring that with regular use, you will always have ample space for your emails and attachments. As a result, you can communicate confidently, knowing your privacy is our utmost priority.
