What Aion does before it quits anything

Aion is conservative by design. It checks what the app is doing before it quits anything.

Unsaved work comes first

If an app still needs your confirmation to save or close, Aion leaves the final decision to you.

No forced close in normal auto-cleanup

Day-to-day cleanup uses normal macOS quit behavior with protection checks, not an aggressive kill routine.

Active tasks stay protected

Downloads, playback, and mic or camera activity can pause cleanup until the app is truly idle.

Context-aware auto-quit for macOS

Why Aion feels safer than timer-based auto-quit tools

Most auto-quit utilities only look at idle time. Aion also looks at what the app is still doing before it decides to clean it up.

A browser is still downloading a large file
Typical timer-based tools

May still be treated like normal background idle time after the timeout expires.

Aion

Network activity can keep the app protected instead of being quit too early.

You are on a call or recording something
Typical timer-based tools

Only sees that the app has been in the background for a while.

Aion

Mic and camera activity are part of the protection logic.

Work mode and personal mode should behave differently
Typical timer-based tools

Usually requires the same idle rule for everything.

Aion

Modes, Focus sync, and per-app rules let you tune behavior by context.

A tiny utility app is only needed for 20 seconds
Typical timer-based tools

Still behaves like a normal app with a normal timeout.

Aion

Instant Task mode lets short-lived utility apps disappear right after use.

Core capabilities

Idle cleanup you can trust

Aion does not rely on a blunt timer alone. It closes apps when they are truly idle, with per-app timeouts when you need them.

Context-aware modes

Use different rules for work, meetings, and personal time instead of forcing every app into the same timeout.

Auto Hardware Guard

Real-time detection for mic and camera usage. Aion automatically protects your apps during meetings, recordings, or live sessions.

Live app visibility

See which apps are open, what they are using, and why they were protected or cleaned up from the menu bar.

Focus mode sync

Tie rules to macOS Focus Modes so your cleanup behavior changes automatically with your day.

Installer cleanup

Automatically eject leftover installer DMGs after an app is moved into Applications, and clean old Aion mounts in the background.

For local automation

Protect apps while your AI is actively working

Aion can protect an app while a local AI or agent workflow is actively using it, instead of treating that app like ordinary background idle time.

Same-user local integration

The current integration is local-only: a same-user socket between Aion and your local automation runtime.

One close-check before quit

After lease expiry and grace, Aion can ask the live holder once whether it should allow close or extend protection.

Public guide, clear boundary

The public guide documents the stable message flow you can rely on, without freezing every internal implementation detail forever.

If you are building a local browser agent, editor agent, or other automation runtime that should keep an app open while it works, start with the public AI integration page.

Frequently Asked Questions

Will Aion close apps that have unsaved work?

Traditional timers blindly count down and often kill apps during meetings or active downloads. Aion features 'Task Insight' that monitors mic, camera, media playback, and network activity. Crucially, Aion uses standard macOS quit flows first, allowing apps to show unsaved-work prompts instead of force-quitting them.

What does the Free version include?

Free is not a short trial. It includes basic auto-quit, whitelist/blacklist, and live resource insights. Pro unlocks unlimited Focus Modes, unlimited app rules, app variant detection, and iCloud sync.

How do refunds work?

Pro purchases are covered by a 14-day refund policy. Email support with your order email and request a refund within 14 days of purchase.

How many Macs can I use?

The single license is for 1 Mac. The 3-Mac Pack covers up to 3 Macs you own, such as your personal and work devices.

Does my app usage data leave my Mac?

No. App monitoring and rule decisions run locally on your Mac. If you make a purchase, only the information needed to complete the order is handled during checkout, not your app activity data.

Is Aion a subscription?

No. Pro is a one-time purchase with lifetime updates under the current policy.
