Privacy & Data

How we handle your data and protect your privacy.

Tenant Isolation

Each user has an isolated workspace:

• Your uploaded documents are stored separately from other users
• Your chat history is private to you
• Other users cannot see, search, or access your workspace
• Your data is logically and physically separated from other tenants

Data Storage

Your data is stored securely on Google Cloud Platform:

• Location — US regions (us-central1)
• Encryption at rest — All data is encrypted using Google-managed encryption keys
• Encryption in transit — All connections use TLS 1.2+
• Access controls — Strict IAM policies limit access to production data

What We Don't Do

• We don't train models on your data — Your uploaded documents are not used for model training
• We don't share your data — Your data is not shared with third parties for marketing or other purposes
• We don't sell your data — Your data is never sold
• We don't access your data — We don't read your documents except for troubleshooting at your request

Source Transparency

CPI is designed for transparency:

• Every claim in a response is linked to its source
• You can click any citation to read the original paper
• The research corpus contains only publicly available academic papers
• We don't make claims that can't be verified

This transparency is core to CPI's value proposition: you should never have to “trust” an AI output — you should be able to verify it.
