We’ve got history.

This means that Queue only stores timestamps and recipient information for your iMessages, Phone calls, FaceTime chats, and Mail threads, never the content itself. In fact, Queue’s servers never have access to your message or email content, or the summaries that can optionally be generated, at all. Everything is analyzed locally on your Mac by on-device Apple Foundation Models to determine which messages belong together in a conversation, whether you seem “caught up”, and to optionally generate a summary to show in the Queue app. Those summaries are stored in your private iCloud so they’re available across all your devices, and only you and your devices can read them. Content stays on your devices, summaries stay in your iCloud, and only timestamps and participants ever reach Queue’s servers.

No. Absolutely not. Ever.

If you choose to enable syncing, the Queue app for macOS will request permission to read data from a few specific folders on your Mac: one that contains your iMessage conversations, one that contains your Phone and FaceTime history, and one that contains your Apple Mail threads. Queue doesn’t have access to any other folders on your computer, and will never write anything to any of these locations. And you can absolutely grant access to any combination of them. Or none.

For Mail, iMessage, FaceTime, and Phone syncing you’ll need a few things: a Mac running macOS 26 Tahoe or later, the Queue app for macOS, iCloud set up so that your messages and calls are syncing to that Mac, and / or Apple Mail set up with one or more email accounts syncing to that Mac. Calendar, Contacts, Google, and LinkedIn syncing work from the Queue app on any of your devices. All syncing requires an active Queue subscription

Yes! You can turn Mail sync, iMessage sync, Phone call sync, FaceTime sync, calendar sync, and conversation summary generation on and off independently. And you can turn communication syncing on or off for specific people in your queue. So if you want to sync messages but not phone calls, or generate summaries for some people and not others, or any other combination of settings for any combination of people, you can absolutely do that.

Queue stops syncing it immediately. For the Mac sources you can also revoke Queue’s folder access entirely in macOS System Settings, and Calendar and Contacts access work the same way in your device’s settings. Google and LinkedIn can be disconnected in the app at any time. And if you ever delete your Queue account, everything stored on Queue’s servers is deleted as well.

When a calendar event has exactly one other attendee and that person is in your queue, Queue automatically records it as a catch up. Apple Calendar events sync right on your iPhone or Mac, and Google Calendar events sync in the cloud once you’ve connected your Google account and enabled Google Calendar access. Queue can also suggest adding new people you meet with to your queue.

Queue will automatically attempt to find public LinkedIn profiles for the people in your queue and sync their career information. It’ll also monitor their profile regularly for updates and optionally let you know when their role, company, or location changes.

For Mail, iMessage, FaceTime, and Phone syncing: yes. Queue can only sync when your Mac is both turned on and awake from sleep. If it does fall asleep or get turned off during a sync, it’ll simply pick up where it left off when it’s back in business. Apple Calendar and Contacts are also synced from the Queue app on your iPhone, which listens for changes even when your Mac is offline. Google Calendar and LinkedIn syncing happen in the cloud, so they keep working even when all your devices are off.

SMS messages will be synced if iMessage forwarding is active for your phone number. WhatsApp messages won’t sync (yet!) unfortunately. And as Queue is designed for Apple platforms for the moment, Android is unfortunately not supported at this time either. Oh, and if you’re wondering about Gmail: any account you’ve added to the Mail app syncs, Gmail included.
