## What it is
Cryptomator is an open-source desktop and mobile application that provides transparent client-side encryption for files stored in any cloud storage service. It creates password-protected vaults with AES-256 encryption of files and filenames, exposed as a virtual drive.

## Use cases
- encrypt files before uploading to dropbox or google drive
- protect documents in onedrive with client-side encryption
- zero-knowledge encryption for cloud storage
- encrypt filenames and file contents in the cloud
- access encrypted vault on android and ios
- secure team cloud storage with access management

## When to choose
- you want open-source, auditable encryption for any cloud provider
- you need cross-platform vaults shared across desktop and mobile
- you prefer simple password-based vaults without key management

## When to avoid
- you need full-disk encryption rather than per-vault cloud encryption
- you require server-side or enterprise key management beyond Cryptomator Hub
- you need encrypted backups with deduplication like restic
