EndPaper Mail is a private, security-first email app from Alien Tech Services LLC.
Sign in to your EndPaper Mail address, or connect Gmail, Yahoo, iCloud, Fastmail, Zoho, GMX or any IMAP mailbox. Mail from other providers goes straight from that provider to your phone over verified TLS. It never passes through EndPaper servers.
Built for security
• End-to-end encryption between EndPaper users with post-quantum keys. Only devices that hold your keys can open the message.
• A public key log checks every recipient's key, so a server can't swap keys without your phone noticing.
• Send a password-protected message to anyone, on any provider. They read it and reply securely.
• Sign-in uses the OPAQUE protocol, so your password never reaches our servers. Authenticator codes add a second step.
• Saved passwords and keys are sealed in your phone's hardware keystore and are never backed up to the cloud.
• Lock the app with your fingerprint, face or PIN.
• Block screenshots and screen recording of your mail. The recent-apps preview is always hidden.
Private by default
• Remote images stay blocked until you allow them, so senders can't track when you open a message.
• The app warns you before it opens a link whose text and address don't match, or that points to a look-alike name or a raw IP address.
• Attachments on EndPaper Mail pass a virus scan before download.
• Remove location and camera details from photos before you send them.
• Notifications hide the sender and subject unless you turn previews on.
• No ads, no analytics and no tracking code.
