SpaceFillStudio
ENTERPRISE SECURITY & PRIVACY

Built with zero-retention privacy by design.

Your forms, resumes, and personal records are processed locally in your session. No remote database storage, no tracking, and zero model training.

🔒

On-Device Local Processing

Form parsing, field coordinate calculations, and PDF object compilation run locally on your device. Your sensitive PDFs are never uploaded to persistent cloud storage buffers.

🚫

Zero AI Model Training

We never use your resumes, biographical notes, tax filings, or completed submissions to train, fine-tune, or evaluate external AI models. Your proprietary data stays entirely yours.

🎯

Vector-Accurate PDF Injection

Rather than converting pages into unencrypted flat images, SpaceFill directly modifies the PDF’s internal AcroForm objects. Original fonts, barcodes, and digital seals remain 100% compliant.

🛡️

Session File Isolation

Every form session is isolated in temporary memory. You can wipe all uploaded sources and session memory with a single click at any time.
