Is 4chems.com GDPR compliant?
Yes — the entire 4chems.com platform is fully GDPR compliant. We implement strict data protection, access control, and transparency measures in accordance with the EU General Data Protection Regulation (Regulation (EU) 2016/679).
What cloud provider or data center is being used?
4chems.com operates on a secure, EU-based cloud infrastructure designed for regulatory and scientific data workloads. Our Solution is provided through ISO 27001–certified European data centers with redundant availability zones to ensure high availbility and data resilience. To avoid compliance risks we do not use Hyperscalers like AWS, Microsoft Azure or Google Cloud.
What version of CHESAR are you running and how often is it updated?
At 4chems.com, we run the latest officially released version of CHESAR, fully synchronized with the ECHA publication cycle. Our CHESAR environment is updated within a few days after each ECHA release, ensuring full compatibility with the current IUCLID data format and the most recent REACH Chemical Safety Assessment (CSA) requirements.
Who owns the data hosted in your solution?
At 4chems.com, our customers always retain full ownership of their data. We act solely as a data processor under GDPR, while the customer remains the data controller. All information including IUCLID datasets, CHESAR assessments and QSAR models, belongs entirely to the customer. 4chems.com does not access, share, or use customer data for any purpose other than providing the contracted service. Upon request or contract termination, customers can export or permanently delete all their data. Backups and replicas are securely maintained only for availability and integrity, in compliance with GDPR and data retention policies.
What version of IUCLID are you running and how often is it updated?
At 4chems.com, we always maintain the latest official release of IUCLID, aligned with the European Chemicals Agency (ECHA) schedule. Our IUCLID environment is currently running the latest production version published by ECHA (updated immediately after each official release). We typically update within a few days of every ECHA release, ensuring full compatibility with REACH, CLP, and OECD formats.
Who handles system administration?
4chems.com manages all platform-level administration, ensuring the environment remains secure, up-to-date, and compliant. Customers do not have access to the underlying infrastructure.
