Your inbox is not our product.
SipherMail is made by Sipher Ltd. We build around people, not advertising.
What we hold to
Privacy first
End-to-end encryption is built in, and we never sell your data. We can’t read messages you send with it.
Built around real needs
Every feature is designed around what people need, not advertising metrics.
Free to leave
Use other mail apps with SipherMail, and take your mail with you any time.
