Can I put the sealed bundle in Dropbox?

Read the NDA carefully. 'No cloud storage of the material' usually means no — even encrypted, some clients treat any copy on a cloud provider as a violation.

An encrypted external drive kept at home is the standard fit. USB sticks work for smaller folders.

Answers/The professional queries

How freelancers keep NDA-covered work off their sync services

An NDA that says 'no third-party cloud storage' means iCloud, Dropbox, and Google Drive are off the table for the material in scope. The clean answer is one folder that lives outside every sync directory, sealed at rest, backed up to an encrypted external drive. Everything else — invoices, generic work — can stay in your normal workflow.

The split

One directory tree for NDA work, outside iCloud/Dropbox/Drive. Encrypted at rest. Backed up manually to an external drive.

Everything else in your normal cloud folder. The NDA does not care about your invoicing.

The tool

Elba is one HTML file. Seals the NDA folder into a bundle. AES-256-GCM. No account, no server, no telemetry. Nothing to declare on a security questionnaire beyond the primitive used.
