Trust & Data Privacy
Your knowledge stays yours.
Penumbra is where you put the work that matters most — competitive analysis, proprietary frameworks, strategic thinking, institutional knowledge. We built the platform knowing that's what it would hold.
So we made a simple commitment: your knowledge belongs to you. It's encrypted, it's private, and it's never used to train AI models. When you put something into Penumbra, the only person who benefits is you.
Data Ownership
What goes in stays yours.
Encrypted & Secure
All data is encrypted at rest and in transit. Your content lives on our infrastructure — not spread across third-party services.
Never Used for Training
We don’t use your information to train models. Your knowledge serves you, period.
Clean Deletion

AI Processing
Your content is used to serve you. Period.
Your content is processed by AI providers only to deliver the features you're using — extraction, querying, analysis. We don't train models on your content.
Your data flow
Do your best thinking. We've got the rest.
