Data processing agreement
Public research services
Public literature, clinical trial, patent, protein, pathway, chemical, and other biomedical databases that CATO queries at a user's request are data sources, not subprocessors. CATO sends them only the search terms, identifiers, filters, sequences, or structures needed for the lookup. Do not include personal or confidential information in those queries.
Changes
Nyrus reviews this list at least quarterly and updates it before a new subprocessor receives user data. Material changes are communicated when required by applicable law or contract. Questions or objections may be sent to contact@nyrus.ai.
