This warning appears because Smoothie Scroll is not currently "code signed" with a certificate from a recognized Certificate Authority. Code signing is a process where a software publisher obtains a digital certificate to verify their identity and ensure the software hasn't been tampered with.

For independent developers or small projects like Smoothie Scroll, obtaining and maintaining these code signing certificates can be quite expensive, often involving annual fees that can run into hundreds of dollars. While code signing provides an extra layer of trust, its absence doesn't mean the software is unsafe. Smoothie Scroll is built with privacy and performance in mind.

You might need to click "More info" and then "Run anyway" (on Windows SmartScreen) to proceed. I understand this can be an extra step, and appreciate your trust! Make sure you are downloading Smoothie Scroll directly from website.

Yes, PRO allows you to exclude specific applications from smooth scrolling.

No. Smoothie Scroll is privacy-focused and collects no telemetry or personal data.

It's highly optimized with minimal CPU and memory footprint, having negligible impact on system performance.

Absolutely. PRO users can finely tune scrolling physics, sensitivity, inertia, and animation smoothness.

Zooming (Ctrl+Scroll) is complex because different applications interpret this action in very diverse ways (e.g., text zoom, UI zoom, tool-specific functions). Trying to implement custom smooth zooming that works perfectly and reliably across all these varied applications is technically not possible.

For stability and a consistent user experience, Smoothie Scroll treats zoom behavior as a simple global setting. In the Global Settings tab, you can choose "Use Native Zoom for Ctrl+Scroll". If checked (default), Smoothie Scroll will not interfere with how applications normally handle zoom. If unchecked, Smoothie Scroll will apply its global smooth scrolling animation as a "scroll-to-zoom" effect. This global approach ensures predictable behavior and avoids performance issues or conflicts with individual applications' native zoom functions.

Smoothie Scroll mainly improves desktop and productivity apps. Most games handle scrolling internally, but you can easily disable it for games.

PRO licenses periodically validate online every 15-30 days to ensure continued activation.
