Cryptomator encrypts your files and folders before they sync to the cloud

Cryptomator creates an encrypted vault on your computer, then encrypts each file locally before it is synced to the cloud when using services like Dropbox, Google Drive, and OneDrive. Cryptomator uses AES-256 encryption to secure each file individually while also protecting filenames. This keeps your data private even if your cloud storage provider is compromised. How does Cryptomator work? Cryptomator creates encrypted vaults on your computer or mobile device. Files are encrypted before being uploaded to the cloud, ensuring that only you or authorized users can access them. What encryption does Cryptomator use? Cryptomator uses AES-256 encryption. Each file is encrypted individually, and filenames are also protected. Is Cryptomator open source? Yes, Cryptomator is fully open source, and its source code is publicly available for independent review and security auditing. Which cloud services does Cryptomator support? Cryptomator is cloud-independent and works with Dropbox, Google Drive, OneDrive, pCloud, Nextcloud, ownCloud, and many other services. You can create multiple vaults and use different cloud providers at the same time. Can Cryptomator be used without cloud storage? Yes, Cryptomator can encrypt files stored locally, on USB drives, or in network folders without syncing them to the cloud. It is also available for Android and iOS for accessing and managing encrypted files on mobile devices. What happens if I lose my Cryptomator password? Cryptomator cannot recover a lost password or decrypt your files for you. If you have created a recovery key, it can be used to reset the vault password, so it should be stored somewhere safe.
