Global Privacy Policy

1. Scope of Operational Data Collection

Opintell distinguishes between Personal Identifiable Information (PII) and Industrial Operational Data (IOD):

• Account PII: Names, corporate email addresses, and encrypted session credentials managed securely via Supabase Auth.
• Industrial Operational Data (IOD): Uploaded PDF machine manuals, SOP guidelines, technical schematics, and operator diagnostic queries.

We understand that IOD contains proprietary trade secrets and manufacturing workflows. We treat all uploaded documentation with strict technical and organizational isolation.

2. Vectorization & Zero Training Guarantee

When you upload a machinery manual, our asynchronous pipeline extracts the text via PyMuPDF (with vision OCR fallback), chunks it into semantic segments, and creates mathematical vector embeddings using Google Gemini models. Vectors are indexed in PostgreSQL using the pgvector extension.

3. Sub-Processors & Infrastructure

Opintell does not sell, rent, or commercialize your factory data. We rely on a minimal set of enterprise-grade cloud sub-processors:

4. Cryptographic Wiping & Retention

When an authorized administrator deletes a document or closes a workspace:

• The original PDF file is deleted from Cloudflare R2 object storage.
• All corresponding text chunks and vector embeddings in PostgreSQL pgvector are cascade-deleted immediately.

5. GDPR & Global Compliance

Opintell complies with the European Union General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and India's Digital Personal Data Protection Act (DPDP). Users maintain full rights to request data exports or demand permanent account erasure.
