Place of data processing and ways of transmission

Santen UK Limited is located in England. Santen also operates through affiliates in Japan and other countries around the world. Personal data about you may be accessible to Santen EMEA affiliates as well as, to the extent permitted by applicable data protection law, to Santen affiliates outside European Union (“EU”)/European Economic Area (“EEA”), and to selected vendors and partners, established in the UK, EU/EEA or globally.
Where Santen processes personal information in countries that may not provide the same level of data protection as in the in UK, Santen will implement reasonable and appropriate legal, technical and organisational security measures with the aim to ensure the security of the processing and in particular to protect your personal data from unauthorised access, use or disclosure.
In the absence of an adequacy decision, Santen will implement appropriate data transfer mechanisms (such as the EU and/or UK Standard Contractual Clauses (SCCs)) or any other officially approved data transfer mechanism, for any cross-border data transfers from the UK to an affiliate or a third party (controller or processor) located in a third country outside of the UK and/or outside of the EU/EEA with the aim to secure such transfers and achieve an adequate level of data protection.

Contractual arrangements with third parties and international data transfers

As a data controller, Santen aims to establish a high level of data protection and privacy for its data subjects and partners alike. To that end, Santen has developed and uses specific privacy and security related language in its contractual arrangements with third party service providers acting for the benefit of Santen as data processors in compliance with applicable data protection legislation.
Through its privacy-compliant contractual arrangements, Santen sets out the scope, subject-matter, duration and purpose of the data processing activities carried out by its data processors and their sub-processors (if any) as well as the types of personal data processed and the involved categories of data subjects. Moreover, details are provided with regard to the service provider’s obligations in its role as data processor which include indicatively its confidentiality obligations, the procedure to be followed in case of a data breach incident, cooperation regarding inquiries from data subjects and authorities, assistance for the performance of data protection impact assessments, international data transfer mechanisms to be executed in the case of cross border data transfers, specific rules for the due diligence and engagement of sub-processors, implementation of appropriate security measures and personal data breach indemnification commitments.
Our service providers are required to be transparent and inform us in advance about their affiliates and any external collaborators (acting as sub processors) that might be involved in processing activities. In case that a service provider and/or any of its collaborators, are located outside the UK, we request where necessary that they also execute appropriate data transfer mechanisms with such third parties to cover any onward transfers; in particular the EU Standard Contractual Clauses (SCCs) or other approved transfer mechanism, in the absence of an adequacy decision and/or any other data protection related certifications implemented by such third parties. This approach establishes and maintains a high level of data protection and privacy for the individuals we interact with in the UK and beyond.

Disclosure of personal data

Personal data are not disseminated to unspecified recipients. Santen discloses your personal data to third party recipients on a need to know basis where this is reasonably permitted to pursue its legitimate business aims and as required by applicable law. Your personal data will be disclosed only in accordance with applicable laws, and appropriate safeguards through contractual agreements, will be established to protect your personal data.
We may disclose your personal data to third parties with which we have a contractual relationship in order to supply products and services to you on our behalf. These may include payment processing, delivery of goods, search engine facilities, advertising and marketing. In some cases, the third parties may require access to some or all of your data. Where any of your data is required for such a purpose, we will take all reasonable steps to ensure that your data will be handled safely, securely, and in accordance with your rights, our obligations, and the obligations of the third party as set forth under the law.
We have currently engaged directly or indirectly the following third parties to provide us with related services: Butterflies Healthcare Ltd, Royal Mail, Pick Pack Dispatch, APC, Google, MailChimp, Inland UK, PayPal, Stripe, Inc.
