Cryptomator
Cryptomator is an open-source encryption app for macOS that helps you protect files stored in cloud folders with password-protected vaults.
What is Cryptomator?
Cryptomator is a security and privacy app for macOS that helps users encrypt files before storing them in cloud services or other synced folders. It is designed for people who want control over the privacy of documents, photos, and other personal or work files without changing their preferred storage provider. Cryptomator creates encrypted vaults that you unlock with your own password, then lets you work with the decrypted contents through the app and Finder-based workflows. It supports common storage locations such as iCloud Drive, Dropbox, Google Drive, OneDrive, network shares, and local folders. The desktop app is available for macOS, Windows, and Linux, making it useful for people who need the same encrypted file workflow across multiple computers. Cryptomator is published by Skymatic GmbH and is widely used as a practical tool for cloud file protection.

Safety overview
Status: Safe
Cryptomator is legitimate encryption software, and its access to files you place in its vaults is central to how it works. On macOS, you may also encounter setup steps for Finder integration or volume access methods so the app can present unlocked vault contents more smoothly. Keep your vault passwords and recovery information in a safe place, because losing them can prevent access to your encrypted files. If you stop using the app, make sure any important files from unlocked vaults are accessible before removing it.
Recommendation: Keep Cryptomator if you use it to protect files in cloud storage or shared folders. Remove it only if you no longer use its encrypted vaults and have already confirmed you can access or safely archive the data you need.
