We designed our phone, video, and text services (Silent Phone and Silent Text) to be completely end-to-end secure with all cryptography done on the clients and our exposure to your data to be nil. The reasons are obvious — the less of your information we have, the better it is for you and for us.
Silent Mail has thus always been something of a quandary for us. Email that uses standard Internet protocols cannot have the same security guarantees that real-time communications has. There are far too many leaks of information and metadata intrinsically in the email protocols themselves. Email as we know it with SMTP, POP3, and IMAP cannot be secure.
And yet, many people wanted it. Silent Mail has similar security guarantees to other secure email systems, and with full disclosure, we thought it would be valuable.
However, we have reconsidered this position. We’ve been thinking about this for some time, whether it was a good idea at all. Today, another secure email provider, Lavabit, shut down their system lest they “be complicit in crimes against the American people.” We see the writing the wall, and we have decided that it is best for us to shut down Silent Mail now. We have not received subpoenas, warrants, security letters, or anything else by any government, and this is why we are acting now.
We’ve been debating this for weeks, and had changes planned starting next Monday. We’d considered phasing the service out, continuing service for existing customers, and a variety of other things up until today. It is always better to be safe than sorry, and with your safety we decided that the worst decision is always no decision.
Silent Phone and Silent Text, along with their cousin Silent Eyes are end-to-end secure. We don’t have the encrypted data and we don’t collect metadata about your conversations. They’re continuing as they have been. We are still working on innovative ways to do truly secure communications. Silent Mail was a good idea at the time, and that time is past.
We apologize for any inconvenience, and hope you understand that if we dithered, it could be more inconvenient.
