Room to cool down.

ColdBrew ends its session when your Mac reports elevated thermal pressure.

/03

Comfortably private.

No ads or analytics. Sessions work locally; optional iPhone alerts use your private iCloud database.

BEFORE YOUR FIRST BREW

A few good
questions.

Can I download ColdBrew yet?

ColdBrew Awake is being prepared for the Mac App Store with a native iPhone companion. Both apps must finish real-device testing before release. This website previews the experience; it does not install an app or change sleep settings.

Will it work with my MacBook lid closed?

Keep the lid open. Closed-lid sessions are not supported in the current app. Manual sleep and macOS safety actions can also override a keep-awake session.

What happens when a session ends?

ColdBrew releases its own sleep-prevention request. Your normal macOS settings apply again, although another app may still keep the Mac awake.

Does it know when a download or render finishes?

The current app uses timed or indefinite sessions. It does not detect task completion. Choose a duration that works for your task, or stop the session yourself.

Can I choose sounds and quiet hours?

Yes. The Mac app has four optional cues, separate cue switches, volume, and daily quiet hours. Quiet hours silence automatic sounds without stopping your session. Sounds and quiet hours start off for new users. Preview buttons deliberately play even during quiet hours; volume zero and system mute still apply. Try the matching browser controls.

Will my iPhone receive low-battery alerts?

A real Mac-to-iPhone test notification has been confirmed. Release-build testing is continuing before version 1.0 becomes available for both devices. They use the same iCloud Apple Account and optional notification permission. This website only simulates alerts; no notification is sent to your phone.

Does ColdBrew turn dark at night?

Choose Follow Mac in Settings, then Auto in macOS Appearance. ColdBrew follows that system change. You can also keep Light or Dark selected. Appearance and quiet hours are independent.

What about privacy?

Sessions, Mac preferences, and activity stay on your Mac. Optional phone alerts store a random Mac identifier, a generic label, alert timestamps, and notification settings in your private iCloud database. No ads or analytics are included. Read the privacy policy for details.

A little less interruption.

A calm corner of your menu bar.
