Zero-knowledge Encryption

Your files are automatically encrypted on your device, before being uploaded to the cloud.

• We can't read any of your files
• We can't even read the filenames

Only you hold the keys to decrypt your files. So only your devices, and those people you explicitly share with, have access.
