Hide anything on your screen. Instantly.

Scrim is a macOS screen privacy utility that places persistent, floating overlay masks on any part of your screen. It lets you instantly conceal sensitive information like API keys, Stripe balances, database credentials, and personal data during screen sharing, demos, presentations, and livestreams.

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.

Scrim is a one-time purchase of $6 USD. There are no subscriptions or recurring fees. The license covers up to 3 Macs and includes all future updates for free.

Scrim requires macOS 15.0 (Sequoia) or later. It is built natively in Swift and SwiftUI for optimal performance and full system integration.
