What's New

Every release, in plain English.

Locker 0.5.7

July 2026Latest

A cleaner reply, and the basics.

Replies don't shout at you

  • Replying no longer dumps the whole original email into the box as raw quoted text. You get a clean space to write, with the original tucked behind a “••• quoted text” toggle (still sent).

About + Help

  • An About window with the version number, and a Help menu (support + keyboard shortcuts). ⌘N starts a new message.

Fixed

  • Send big files straight from compose via an encrypted Locker Drop link. And the Send buttons no longer get cut off in a small window.

Locker 0.5.6

July 2026

Compose, leveled up.

Undo Send

  • Hit send, then get a few seconds to catch it — a quick Undo before the message actually leaves.

Send Later

  • Schedule a message for in an hour, this evening, or tomorrow morning. It waits in Drafts and goes out on its own.

Choose who you send as

  • A From picker — if you run multiple domains on one account, pick which address a message goes out as.

Fixed + polished

  • Forwarding now keeps the original's attachments (it used to drop them). Start typing a recipient and Locker suggests people you've emailed.

Locker 0.5.5

July 2026

Fixes a launch crash.

Fixed

  • Fixed a crash on launch in 0.5.3–0.5.4 (the app couldn't find its updater component). If Locker wouldn't open, this version fixes it.

Locker 0.5.4

July 2026

A quick one.

Maintenance

  • A small under-the-hood update — and the first one that installs itself with a single click if you're on 0.5.3. Your mailboxes, license, and settings are untouched.

Locker 0.5.3

July 2026

Updates that just… update.

One-click updates

  • This is the last time you'll download a disk image and drag Locker to Applications. From here on, a new version downloads in the background and installs with a single “Install and Relaunch” — no dragging, no disk images. Your mailboxes, license, and settings stay exactly as they are.

Locker 0.5.2

July 2026

Sending a big file? Skip the bounce.

Big-attachment helper

  • Attach a file too big for most inboxes and Locker offers a one-click way to send it as an encrypted, self-destructing Locker Drop link instead — no size limit, decrypted right in the recipient's browser. It only shows up when it's actually useful.

Locker 0.5.1

July 2026

Multiple domains on one account, and a cleaner connect.

Send from any of your addresses

  • Run several domains off one mailbox (like Fastmail)? Add your other addresses under an account, and Locker replies from whichever one the message was sent to — so a note to hello@yourbrand.com is answered from hello@yourbrand.com, not your main login. It even suggests the addresses it already sees in your mail.

Fixed

  • Connecting a mailbox that hiccups on the first try no longer leaves a phantom duplicate account (and any existing duplicates are cleaned up automatically). A mailbox that's already connected won't be added twice.

Locker 0.5.0

July 2026

Try it free for 14 days — no card.

Free 14-day trial

  • New here? Open Locker, enter your email, and the whole app is yours for 14 days — no credit card. You'll see the days left right in the app, and can upgrade to keep it forever whenever you're ready.

Clearer pricing

  • The current offer — including any active discount — now shows inside Locker exactly as it does on the site, so you always see the real price before you buy.

Smoother setup

  • Picking a provider (Gmail, iCloud, Fastmail, Yahoo) now clearly highlights your choice and fills in the right hints.

Locker 0.4.0

July 2026

A real daily driver — steadier sync, notifications that respect you, and your own rules.

Rock-solid sync

  • Fixed the bug that could leave a Gmail account stuck after a hiccup — Locker now retries and recovers accounts automatically instead of going quiet.

Attachments

  • View, download, and send attachments on your Gmail accounts.

Work accounts (beta)

  • Connect a work / Outlook / Microsoft 365 account that blocks IMAP by adding it through Apple Mail, locally on your Mac — no OAuth app, no admin approval. A very large corporate inbox can be slow to fill in (Apple Mail downloads the whole mailbox); best today for Gmail and smaller work mailboxes.

Reply the way you actually do

  • Reply, Reply all, and Forward. Cc and Bcc. Replies thread properly in the other person's inbox.
  • One-click copy of any address in an email — even ones buried in a forwarded chain.

Smart notifications

  • Native banners only for what matters: an urgent message, a security alert, or your morning Brief. Set VIPs that always reach you, mute the noisy ones, pick quiet hours.

Rules + reminders

  • Build your own rules — “when my biggest client emails about invoices → notify me.” Tag any email. Snooze with remind-me and get a banner back at 3pm or tomorrow.

Polish

  • Per-account inbox view. “Search by meaning” now drives the command bar (and never archives by mistake). Faster and more native — now using Apple's own system fonts.

Locker 0.3.0

June 2026

Search that understands what you mean.

New

  • Search your inbox by meaning, not just keywords. Type “baby stuff” and Locker surfaces the Carter's order, the stroller sale, the daycare email — even when none contain the word “baby.” It runs entirely on your Mac.
  • Locker picks its own network ports on launch, so it never collides with other apps.

Locker 0.2.0

June 2026

New

  • Automatic updates — Locker tells you when a new version is out and updates with a click; your mailboxes, license, and settings stay exactly as they are.
  • A real command bar at the top of every screen — type plain English and Locker does it.
  • Sent box — every reply you've approved, with a link back to the original.

Improved & fixed

  • Paste (⌘V) works everywhere. Removing a mailbox is a clear button. The on-device AI stays warm instead of reloading per email. The top search bar is wired up. Marketing mail no longer shows under “needs you.”

Locker 0.1.0

June 2026

First build

  • Locker for Mac — a private AI inbox that runs on your own Mac. Sorted, answered, and protected by the Mac's on-device AI; nothing leaves your device. Signed & notarized by Apple.
