End-to-end encrypted email with post-quantum cryptography.




We built Aster because encrypted email shouldn't require a technical degree or a compromise on features. Your inbox should be private by default , not as an add-on.
All encryption happens on your device before anything touches our servers. We cannot read your emails, and neither can anyone else. On top of standard PGP, Aster uses post-quantum cryptography by default, meaning your emails are protected even against future quantum attacks, and it works when emailing Gmail users too, not just other Aster users.
