LocalInbox for iPhone and iPad: private email, on-device AI

What it does

• Set up from your Mac. Already use LocalInbox on your Mac? Scan a QR code and your accounts come over, passwords and all, on your Wi-Fi, encrypted, never through the internet.
• Every account, one inbox. All your accounts together, sorted into Primary, Updates and Promotions, with To Reply for mail that's waiting on you. Search every account at once, and the server for older mail.
• Summaries, replies and answers. One-line summaries and key points, three suggested replies written as you, Draft with AI and Rewrite, and answers that link to the emails they came from, from Apple Intelligence on the device.
• Today and the Morning brief. The deadlines, trips and bookings found in your mail, on one page, and a Morning brief at the time you choose. Invitations go to Calendar, dates to Reminders, in a tap.
• Snooze, Remind me, Undo Send. Snooze a conversation until later, get a nudge when nobody replies, and see what you're waiting on. Undo Send, Send & Archive, and checks for a forgotten attachment.
• Rules and Unsubscribe. Rules that sort mail as it arrives, the same as the Mac's, categories in your own words, every newsletter in Subscriptions, and Unsubscribe in a tap.
• Face ID, and nothing collected. Lock the app with Face ID. Trackers come out of your mail, passwords stay in the Keychain, and the App Store privacy label is Data Not Collected.
• Made for iPhone and iPad. Notifications for new mail with Copy Code for sign-in codes, Send from the share sheet, Spotlight, Shortcuts and Focus filters. Two columns on iPad.

An iPhone or iPad with iOS 18 or later. Summaries, suggested replies, Draft with AI, Rewrite and Ask your mailbox need Apple Intelligence (iOS 26 on a supported iPhone or iPad).

Set it up from your Mac

Set Up iPhone… in the Mac app's Settings › Accounts copies your accounts across, passwords and all, so nothing needs typing. The iPhone scans the code it shows, and you allow it once with Touch ID.

Tick every account and they arrive together, in one inbox.

Already on your Mac? Don't sign in again

• On the Mac: Settings › Accounts › Set Up iPhone… shows a QR code.
• On the iPhone or iPad: Add Account › From your Mac, and scan it.
• Check that both show the same four digits, and allow it on the Mac with Touch ID or your password. Your accounts come over your Wi-Fi with their passwords, encrypted, never through the internet.
• Your licence key can come the same way: Settings › Licence › Show on iPhone… on the Mac, and Scan from your Mac on the iPhone or iPad.

Private by design

• There's no LocalInbox server. Your mail goes between your iPhone and your mail provider, nowhere else.
• Apple's model runs on the device, so no AI cloud reads your mail.
• Passwords stay in the Keychain. No analytics, no crash uploads and no tracking: the App Store privacy label is Data Not Collected.
• Trackers are taken out of your mail, and Settings › Privacy shows the week's count.
• Lock the app with Face ID.

One licence for the Mac, iPhone and iPad

Bought LocalInbox for Mac? Your licence key unlocks it here too. A key bought on this site unlocks the iPhone and iPad too, and each device uses one of the key's 3 places.

Bought in the app instead? It goes through the App Store at the same price. Your iPhones and iPads on that Apple Account are unlocked and use none of the 3, and Settings › Unlock LocalInbox › Get Your Mac Licence Key gives you a key for your Mac.

How it differs from the Mac app

• The AI is Apple's model only. A phone runs no model server, so Ollama and LM Studio are for the Mac.
• New mail comes with background refresh, which iOS runs when it chooses, so a notification can come late. While the app is open, new mail arrives at once, as on the Mac.
• Proton Mail isn't offered: Proton Mail Bridge runs on a computer.
• Each device syncs with your mail server on its own: mail, read and flagged state, folders and drafts stay in step through the server. Accounts come from your Mac once, with a QR code, or are added on the iPhone with their passwords, and settings don't sync between devices yet.
• Send Later is on the Mac only.

iPad and iPhone Duo

LocalInbox lays out by the width it has, never by the device. On iPad, and on the iPhone Duo's inner screen on its side, the list and the conversation sit side by side. Each window keeps its own place, so folding, unfolding and Split View don't lose it.

Your mail on iPhone

Gmail, iCloud Mail, Yahoo, AOL, Fastmail, Zoho, GMX and any IMAP account. Each page says what the provider offers on iPhone and how LocalInbox works with it.
