Private.Ki Mail is an email service that encrypts messages between Private.Ki users. Message bodies, subjects, and attachments are encrypted on the sender’s device and decrypted on the recipient’s device, with encryption and signature checks shown for each message. Mail to outside providers uses end-to-end encryption when the recipient has a PGP key; otherwise it is delivered normally and marked accordingly. The Free plan costs nothing and includes one @private.ki address, encrypted email and messenger, signatures, recipient autocomplete, search, and attachments up to 25 MB per file. Undo send supports 5, 10, 20, or 30 seconds, and standard mailbox folders are included. Web, iOS, and Android access are listed. Security features include TOTP two-factor authentication, QR pairing, and device-bound sessions. The maker says it cannot recover a lost passphrase or protected key and has no independent audit yet.
