Scrim: Cover sensitive info on your Mac while you screen share

Hey Product Hunt 👋 I'm Abdelhak, the maker of Scrim.

I built Scrim because sharing your screen on a Mac shouldn't mean closing every window that has something

sensitive in it.

Scrim puts floating masks over any part of your screen, so API keys, dashboards, customer data, or

notifications stay hidden while you share, present, or stream.

What it does:

- A global hotkey creates a mask; drag it into place and it snaps to screen edges and center

- Click-through mode: keep working in the app underneath while the mask stays on top

- Blackout, frosted glass, or soft tint styles

- Presets that switch automatically per app, and mask groups

- Multi-monitor support and a menu bar for quick control

- Optional: masks show up automatically when Zoom, Teams, OBS or another screen-sharing app starts

- Native Swift, and the app has no telemetry

It's free to download (up to 2 masks). A one-time license (no subscription) unlocks unlimited masks, presets,

groups and custom hotkeys.

I'd love your feedback on:

1. Which apps or workflows would you want masked first?

2. Should masks follow a window when you move it, or stay fixed on screen as they do today?

3. What would make you trust it enough to leave it on for every call?

I'll be here answering everything. Thanks for taking a look!
