Most email apps now quietly send your mail to a cloud AI — for summaries, smart replies, "priority" ranking. WhoMail doesn't. Your email never leaves your device for an AI service. Ever. WhoMail is a fast, genuinely private email app for iPhone, iPad and Mac that brings Outlook, iCloud, Fastmail, Yahoo and any IMAP account into one unified inbox. WHAT MAKES IT DIFFERENT • No cloud AI. Ever. Your messages aren't uploaded, summarised, scanned, or used to train anything. Anything that feels smart happens on your device. • Know your people. WhoMail builds a private picture of who you actually email — your reply times, how often you talk, your busiest hours, and a profile for each contact assembled from their own email signatures. No other inbox shows you this. • Push that stays blind. New Outlook mail arrives the second it's sent, even with the app closed — but our relay only ever learns "this mailbox got something." The sender and subject are fetched on your phone, by your phone. • One unified inbox across every account, or jump to any single mailbox in a tap. • Native and fast — opens, syncs and searches instantly, with a calendar built in. PRIVACY ISN'T A FEATURE HERE — IT'S THE DESIGN • No AI servers. No mail content on our servers. No tracking, no ads, no profile of you sold to anyone. • You sign in straight with your provider; your tokens stay in the device keychain. • Turn our push service off tomorrow and you lose nothing but a little speed. Supports Outlook / Microsoft 365, iCloud, Fastmail, Yahoo and standard IMAP. Built by Calligo IT. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
