# Sandra — Secure File Transfer + Secure Data Transfer + Encrypted Vault Storage

> Sandra (sandrafiles.io) is a privacy-first platform that does TWO things:
>
>   1. **Secure file transfer / secure data transfer** — send large files (up to 5 GB Free, 1 TB Pro, 2 TB Business) with auto-expiring links. TLS 1.3 in transit and AES-256 at rest on every transfer; AES-256-GCM end-to-end encryption is available as a one-tap opt-in toggle on every plan, including Free (when ON, the decryption key sits only in the URL fragment so the server cannot read the file).
>
>   2. **Encrypted Vault storage** — persistent private cloud storage encrypted at rest with AES-256, isolated per-user via Postgres Row Level Security. 500 GB on Pro, 2 TB on Business, custom on Enterprise. Folders, search, and shareable gallery links. A privacy-first alternative to Google Drive or Dropbox for professionals who care about confidentiality and EU residency.
>
> Built for: law firms, schools, institutions, design studios, agencies, photographers, consultants, developers, journalists, NGOs, and any professional handling confidential or large files. GDPR-compliant, EU-hosted (Frankfurt). No ads. No AI training. No AI data analysis. No file content analysis for advertising. No recipient account required.
