Ajour GitHub

Let the login
code in. Keep the spam out.

Ajour turns a SimpleLogin alias on for a few minutes and off again, from your Mac's menu bar. That's all it does, and it is unreasonably proud of it.

Download Ajour for Mac

Free and open source · macOS 26 or later

The Ajour menu open below its menu bar icon. One alias has a timer with 4 minutes left, and the actions for another timed alias are open: Copy Address, Disable Now, Keep Enabled, and Extend.
That menu is the whole app.

The old way, a tragedy in six acts

  1. Act IA website wants to email you a login code.
  2. Act IIIts alias is disabled, because this website has never sent you anything but spam.
  3. Act IIIYou open the SimpleLogin dashboard and scroll past 200 other aliases to find it.
  4. Act IVYou enable it, go back, request the code again, and wait.
  5. Act VThe code arrives. You log in. You feel accomplished.
  6. Act VIYou forget to disable the alias. Three weeks later, the newsletter finds you.

The end. Nobody claps.

The Ajour way

  1. The Pinned section of the Ajour menu with the disabled alias online-shops selected.

    Click the alias in the menu bar.

  2. The alias's submenu with Copy Address and Enable for 5 Minutes, 1 Hour, or 24 Hours. Enable for 5 Minutes is selected.

    Enable it for 5 minutes and log in.

  3. A notification: Mail received. Alias turns off at 14:58. online-shops@alexmorgan.example from login@shop.example. It has a Disable Now button.

    Disable it when the mail arrives.

    A notification offers to disable the alias. Ignore it, and Ajour disables it when the time is up.

And this time, there is no Act VI.

Small app, surprisingly many opinions

The All Aliases window with a search field, four pinned aliases, and other aliases, each showing whether it is enabled, disabled, or how much time it has left.

Timers for aliases.

Turn any pinned alias on for 5 minutes, 1 hour, or 24 hours. The menu counts down and tells you when the alias turns off. You can extend the timer, keep the alias on for good, or turn it off early.

Mail alerts with an off switch.

While a timer runs, Ajour checks the alias every 15 seconds. When mail arrives, the notification has a Disable Now button.

No alias left behind.

If your Mac was asleep or Ajour wasn't running when a timer ended, Ajour disables the alias as soon as your Mac wakes or the app starts again. If you quit Ajour, it disables timed aliases first.

Every alias, searchable.

The All Aliases window searches your whole account. Pin the ones you need to the menu.

The New Alias window with the prefix concert-tickets, a suffix of one of your domains, and a preview of the full address.

New aliases in one click.

Create a random alias and get it on your clipboard, optionally with an expiry date. Or pick your own prefix and one of your custom domains.

The Settings window with the account, a Launch at login switch, and the About section.

Out of your way.

Ajour lives in the menu bar, has no Dock icon, and can start at login. Every alias state has its own symbol and word, and VoiceOver reads them too.

Reviews from the other side

All reviewers are made up. Any resemblance to your inbox is intentional.

"I used to reach 40,000 inboxes before breakfast. Now I reach an alias that was enabled for five minutes, two weeks ago."

Definitely a courier.

The serious part

We'll stop joking for a moment.

An API key, never your password.
Ajour keeps it in your Keychain and nowhere else.
One destination.
Ajour only talks to app.simplelogin.io.
No analytics.
Ajour has no tracking and no third-party dependencies.
Sandboxed.
The App Sandbox allows outgoing network connections and nothing else.
Signed and notarized.
Releases are signed with a Developer ID and notarized by Apple.
Open source.
The code is on GitHub under the MIT license.
Honest limit.
SimpleLogin can't disable an alias on a schedule, so the timers run on your Mac. If your Mac sleeps through the end of a timer, the alias stays enabled until it wakes and Ajour is running.

Questions

Is Ajour made by SimpleLogin or Proton?

No. Ajour is an independent app built on SimpleLogin's public API. It is not affiliated with SimpleLogin or Proton AG.

What does it cost?

Nothing. Ajour is free and open source under the MIT license.

What do I need?

A Mac with macOS 26 or later and a SimpleLogin account. Ajour signs in with an API key that you create in SimpleLogin; the setup walks you through it.

Ajour disables it as soon as your Mac wakes and the app is running.

Not yet. It's planned.

Can I install it with Homebrew?

Not yet. For now, download the zip, unzip it, and move Ajour to your Applications folder.
