Proton Drive
Proton Drive is Proton AG’s encrypted cloud storage app for macOS that syncs files through Finder and keeps Drive content available across devices.
What is Proton Drive?
Proton Drive is a macOS desktop app from Proton AG for encrypted cloud file storage and synchronization. On Mac, it integrates with Finder through a dedicated Proton Drive location instead of a traditional full desktop window, and it can run in the background from the menu bar. Users place files and folders into the Proton Drive folder to upload them to their Proton account and access them on other supported devices and the web app. Proton documents support for on-demand sync on macOS, so files can appear in Finder as online-only placeholders until downloaded locally, with options to keep items available offline. Proton also provides setup and uninstall documentation for macOS, including app-specific container, preferences, and group container data created by the desktop client. Users commonly encounter it when they want privacy-focused cloud storage, cross-device file access, and closer Mac integration than the browser version provides.

Safety overview
Status: Mostly safe
This is a legitimate Proton AG application for cloud file storage. It handles user documents and sync data, so deleting its app data, containers, or synced files can remove local copies and may affect access to unsynced or online content.
Recommendation: Keep it if you use Proton Drive or store files in its synced Finder location. Remove it if you no longer use the service and have confirmed that any needed files are already backed up locally or in your Proton account.
