Linger
Stay awake while you're here
Only for Mac

Mac
Your computer shouldn't sleep while you're reading, watching, or on a call, and shouldn't stay awake after you've left. Keep it awake only while you're actually there.
Linger keeps your computer awake only while you're actually in front of it, and lets it sleep the moment you step away.
Your computer's sleep timer is simple-minded: it just counts the seconds since your last keypress. So it dims and sleeps while you're reading a long document, watching a video, or thinking on a call. The usual workaround, a "keep awake" app, is the opposite problem: you forget it's on, and your computer never sleeps, draining the battery for hours after you've gone.
Linger fixes both. It uses your built-in camera to check whether you're there:
• You're present → your computer stays awake, even when you're not touching it.
• You walk away → your computer sleeps normally, saving power.
And it's not just "is anyone there." Linger recognizes you specifically (a coworker walking past won't keep your computer awake).
PRIVATE BY DESIGN
• Everything happens on your computer. No image ever leaves the device.
• Camera frames are analyzed in memory and immediately discarded, never saved.
• Only a numeric "faceprint" (not a photo) is stored, and only on your device.
• No account, no network, no analytics, no tracking. Linger doesn't even request network access.
GENTLE ON YOUR BATTERY
The camera doesn't run constantly. While you're typing or clicking, it stays off entirely. Linger only takes a quick look during idle moments, exactly when your computer is deciding whether to sleep. Each check lasts a fraction of a second.
SIMPLE
• Lives in your menu bar, no windows, no clutter.
• Enroll your face once.
• Pause anytime, or force "stay awake" when you need it.
• Open at login and forget it's there.
A note on the camera light: you'll see the green indicator blink briefly each time Linger checks for you. That's operative system protecting you from hidden apps, no app can hide it, and Linger keeps those checks rare and short.
Linger is for anyone whose computer sleeps at the worst moments: reading, watching, presenting, monitoring a long build, or just thinking it through.
