Is Keepresso safe? Open source, notarized, minimal permissions

Keepresso is a small, focused app, and it is easy to check what it does. It is free and GPL-3.0-licensed, so the full source is public, and it is signed and notarized by Apple, so it opens without warnings.

What permissions it asks for

Keepresso asks for very little, and only when you use a feature that needs it:

• Administrator password, once, only when you turn on closed-display mode, because that flips a macOS system setting.
• Location, only if you use a Wi-Fi trigger, because reading the current network name needs it on modern macOS. Nothing else uses your location.
• Notifications, only for the still-brewing reminder.

What it does not touch

• No camera or microphone permission. The meeting trigger reads only the system signal that a camera or mic is in use, the same thing that lights the dots in your menu bar. It never opens a stream.
• No Accessibility permission.
• No trackers, no analytics, no account.

Why it is not on the Mac App Store

The App Store sandbox blocks the macOS power APIs Keepresso relies on to keep your Mac awake. So it ships outside the store, with Apple's hardened runtime on and full notarization, the standard, trusted way to distribute a Mac app that needs those capabilities.
