BlurShield: Blur and lock your mac the moment your lid starts closing

BlurShield blurs your screen the instant your lid starts closing, a paired device goes out of range, or you hit a keyboard shortcut — Touch ID brings it right back. Choose what protects you: a lid-angle sensor, a Bluetooth device that walks out of range with you, or a shortcut you trigger yourself. BlurShield also includes Espresso, a caffeinate replacement built in: keep your Mac awake through long builds, renders, or downloads, without digging through Energy Saver settings every time.

Hey Product Hunt! 👋 I built BlurShield because I kept getting caught off guard — closing my laptop lid halfway to grab something and remembering later my screen was still fully visible, or having someone walk up behind me at a coffee shop with my inbox wide open. BlurShield sits in your menu bar and blurs your screen the instant something privacy-sensitive happens — the lid starts closing, a paired Bluetooth device walks out of range, or you hit your own keyboard shortcut. Touch ID (or your password) brings it right back. Pick from six overlay styles, from a soft frosted blur to a full blackout, and tune how much you want hidden. It also bundles Espresso, a lightweight caffeinate replacement — keep your Mac awake through a long build or render without digging through Energy Saver settings. $1.99 (₹149) one time Would love feedback, especially on which trigger feels most useful to you day-to-day. Happy to answer anything in the comments!

@akash_khatkale Great one. Needed to protect my screen while my claude is running.
