    Security without the jargon.

    01

    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.

    02

    No file analysis

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

    03

    Expiration control

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

    04

    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.
