  • Encrypted transmission (HTTPS/TLS) for all data exchanged with the Website.
  • Access controls limiting who can view personal data internally.
  • Regular review of data collection and storage practices.

No method of transmission over the internet is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.

International transfers​

Your data may be transferred to and processed in countries outside your country of residence. Where data is transferred outside the EEA, we ensure appropriate safeguards are in place (such as Standard Contractual Clauses) to protect your personal data in accordance with this policy.
