Security & Data Handling
How ChemStitch protects your research data. We believe in transparency about what we do and don’t do with your structures.
Data Flow
All connections use TLS encryption in transit.
What We Don’t Do
- ×We don't sell your data
- ×We don't share your structures with anyone
- ×We don't use your data to train AI models
- ×We don't require you to share your AI API key
BYO API Key Architecture
Your key, your costs, your control.
- Keys encrypted with AES-256-GCM before storage
- Keys are only used to make AI requests on your behalf
- You can delete your key at any time from Settings
- Platform default key available during beta
What Data Is Sent to AI Providers
- Structure context (SMILES representation) when you initiate a chat message
- Only sent when you explicitly ask the AI a question
- AI providers process the request and return results; no training on your data
Data Storage
Storage & encryption
- ✓Structures and documents stored in your private account in a managed PostgreSQL database
- ✓Encryption at rest, TLS in transit
- ✓No cross-user data sharing
Authentication
Access controls
- ✓Magic link authentication (email-based, no passwords)
- ✓Session tokens with automatic refresh
