Why Moondust

Privacy is the default, not a setting.

Every account ships with the same protections — whether you're a journalist, a developer, or just tired of being the product.

End-to-end encryption

Mail between Moondust users is sealed in transit and at rest. Even we can't read it.

Zero tracking

No pixels, no profile-building, no ads in your inbox. Open a message and nobody knows.

Email aliases

Unlimited masked addresses, generated on demand. Sign up for anything without ever sharing your real inbox.

Open source

Our entire stack is public and auditable. Verify our privacy promises — don't just take our word for it.
