Keep Stripe balances, databases, API keys, and distracting apps covered. No messy app reconfigurations or window rearranging during demos, livestreams, or DJ workflows.

Protect details with a lightning fast utility that behaves naturally on macOS. Setup is done in less than thirty seconds.
Press your customizable hotkey ⌘⌥M or click the status menu bar icon to spawn a Scrim overlay block.
Position the overlay directly above sensitive metrics or database keys. Scale it to cover the exact pixel boundary.
Present on Teams, Zoom, or Twitch. Swap tabs and applications effortlessly knowing your secrets are locked behind masks.
We understand presentation fatigue. Scrim keeps out of the way, operating reliably as a background macOS utility with robust controls.
Need to block out a variable section of your UI? Draw dynamic squares around code blocks, profile photos, or emails instantly. Resize freely to align precisely over UI containers.
Enable interactive click-through, rendering the mask visually opaque but computationally transparent. Click buttons or highlight text directly underneath your mask without moving it.
Save groups of masks as profiles (e.g., "Stripe CRM", "AWS Console"). Have them apply automatically when specific target windows or domain URLs become active on screen.
Written natively in Swift to run on macOS Sequoia. Draws zero CPU cycles when passive, runs entirely sandbox-offline, and never gathers tracker metrics or calls home.

Got general questions about permissions, licenses, or offline security? We have clear answers.
When click-through is enabled, Scrim makes the overlay window completely transparent to mouse events. This allows you to select code, type, click links, and interact with application UI directly under the mask while keeping the private content hidden from viewers.
Never. Scrim operates completely locally and sandboxed. It does not contain telemetry or internet-facing components. Screen Recording permissions are required by macOS solely so Scrim can position floating mask layers securely over other applications.
Each Scrim license allows you to install and activate on up to 3 of your own Macs. If you change computers, you can deactivate old devices anytime from within the app.
To draw a custom overlay window above other applications and coordinate desktop coordinates, macOS requires Screen Recording and Accessibility permissions. Scrim acts as a pure visual filter — it never writes pixels to disk or network.
Yes! Scrim supports multi-monitor setups. You can create and position masks independently on each connected display. Masks persist across monitor arrangements and workspace changes.
Absolutely. Scrim offers multiple mask styles including frosted glass blur, solid blackout, and soft tint modes. You can adjust opacity, color, corner radius, and save custom presets for different workflows.
