AlterSend
AlterSend is a desktop file transfer app for Mac that sends files directly between devices without cloud storage or account sign-in.
What is AlterSend?
AlterSend is a cross-platform file transfer app for macOS and other devices that helps users send files directly between phones and computers. It is designed for people who want a simple way to move documents, photos, videos, and folders without first uploading them to a cloud service. The app focuses on peer-to-peer transfer, device pairing, and end-to-end encrypted sharing, which makes it useful for personal transfers as well as quick exchanges between your own devices. AlterSend supports Mac workflows alongside Windows, Linux, iPhone, and Android, so it fits mixed-device households and work setups. Devaprime LLC publishes the app. On Mac, users will typically use it when they want a native desktop alternative to browser-based sharing tools or platform-limited options such as local-only transfers.

Safety overview
Status: Mostly safe
AlterSend's network access and device-discovery behavior are consistent with a file transfer app, since it must connect devices and move files between them. Its published purpose includes direct peer-to-peer transfer and end-to-end encryption, which aligns with normal expectations for this category. As with any file sharing tool, confirm the receiving device before sending sensitive files and review any local network or file access permissions you grant on your Mac.
Recommendation: Keep AlterSend if you use it to move files between your devices or share files across different platforms. If you no longer use it, removing the app should mainly affect its file transfer features and any saved pairing convenience. Before uninstalling, finish any active transfers and check whether you want to keep files you received through the app.
