Frequently Asked Questions

Are Great Apps free to use?

All Great Apps are available on the Mac App Store. Most offer a free tier with core functionality and an optional one-time purchase to unlock the full feature set.

Is my data sent to any server?

Most Great Apps process data entirely on your Mac with no internet connection required. Some applications may require server-side processing to deliver their functionality. In such cases, data is transmitted securely, processed, delivered, and immediately deleted from our servers.

What macOS versions are supported?

Most apps support macOS 10.15 (Catalina) or later, with some requiring macOS 11.5 (Big Sur). Check the individual app page for specific compatibility details.

Can I use these apps for business and enterprise?

Yes. Great Apps are designed for professional use including legal compliance, financial reporting, IT migration, and team operations. All processing stays local, which makes them suitable for sensitive enterprise data.
