Who Sandra is for

Four kinds of client work

Legal teams

A private channel for client documents

Client intake, privileged delivery, and matter archive without the email trail. Clients never create an account.

Studios & agencies

The last mile of client work

Clean delivery links for finals, one request link for client assets, and a Vault where approved versions live.

Schools & institutions

Collect every document through one link

Admissions files, consent forms, and board packs uploaded from any browser. No accounts for families.

Confidential documents

An attachment is a copy you no longer control

Payroll, contracts, and personnel records through private expiring links, with end-to-end encryption one tap away.

Why Sandra

Built different. On purpose.

Optional zero-knowledge E2EE

Toggle E2EE on the transfer form (every plan, including Free) and your browser encrypts the file before upload. Sandra's servers see ciphertext only. The key lives in the link, never on our servers.

Premium delivery experience

Branded pages, clean download flows, zero distractions. Every handoff reflects your professionalism.

Control without friction

Password protection, scheduling, tracking. All optional. Use what you need, skip what you don't.

Security

Security without the jargon.

End-to-end encryption

Enable E2EE in one click. Files are encrypted in your browser (AES-256-GCM) before upload. Sandra's servers never have the key. The decryption key lives in the link only. All transfers also use TLS 1.3 in transit.

No file analysis

We never scan, analyze, or peek into your content.

Expiration control

Set exactly when your links expire. Files are automatically purged, no traces left behind.

Download tracking

Know when your files are accessed, by whom, and from where. Full visibility without compromising privacy.

Hosted on GDPR-compliant infrastructure. Data stored in the EU.
