This ensures that your data remains within the jurisdiction of GDPR regulations, providing an added layer of protection.

Regarding data retention and deletion, Lagrange adheres to the following policies:

By implementing these data storage and security measures, we strive to protect your personal data and ensure its confidentiality, integrity, and availability at all times.

6. International Data Storage, Transfer and Processing

In order to provide our users with the Service, we or our third-party providers may need to process your personal data outside of the European Economic Area (EEA), the United States, and other territories. If you are based in the EU, Lagrange will only process or transfer data outside of the EEA in compliance with data protection legislation. We ensure the protection of your personal data by taking the following measures:

  3. Aggregated, Non-Personally Identifiable Information: We may share aggregated, non-personally identifiable information with third parties for auditing, analytics, maintenance, security, or other related business purposes.
