## About

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.

Features

We don't read your emails. We don't sell your data. That's the whole point.
