6. International cross-border data transfers

Because Mereo operates globally, your data may be transferred outside of the country in which you interact with Mereo, including to countries whose data protection laws substantially differ from the country in which you work or reside. To accomplish the purposes described in this Notice, we may also disclose and transfer personal data to personnel and other departments throughout Mereo. For example, your personal data may be transferred or accessed by Mereo and its affiliate entities in the United States of America.

Whenever we transfer your personal data out of the UK or EEA, we ensure a similar degree of protection is afforded to it by ensuring that at least one of the following safeguards is implemented:

· We will only transfer your personal data to countries that have been deemed to provide an adequate level of protection for personal data by the European Commission. For further details, see here.

· Where we use certain service providers, we may use specific contracts approved by the European Commission which give personal data the same protection it has in Europe. For further details, see here or here, for transfers from the United Kingdom.

Please contact us here if you want further information on the specific mechanism used by us when transferring your personal data out of the EEA.

7. Data security

Mereo will implement appropriate technical and organizational security measures necessary to adequately safeguard your personal data. These safeguards will include, for example:

Security Measures

• All employees handling Personal Data receive security and privacy awareness training, will only process your personal data on our instructions and are subject to a duty of confidentiality.

• Employees with access to Personal Data are given the least privilege necessary

• We have robust procedures to deal with any suspected personal data breach and will notify you and any applicable regulator of a breach where we are legally required to do so.

• A disciplinary policy is enforced to prevent unauthorized access

8. Data retention

We will only retain your personal data for as long as reasonably necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, regulatory, tax, accounting or reporting requirements. We may retain your personal data for a longer period in the event of a complaint or if we reasonably believe there is a prospect of litigation in respect to our relationship with you.

To determine the appropriate retention period for personal data, we consider the amount, nature and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means, and the applicable legal, regulatory, tax, accounting or other requirements. By law, we have to keep basic information about our vendors (including contact, identity, financial and transaction data) for six years after they cease being suppliers for tax purposes.

In some circumstances you can ask us to delete your data: see your legal rights below for further information.

In some circumstances we will anonymise your personal data (so that it is no longer your personal information as it cannot be associated with you) for research or statistical purposes, in which case we may use this information indefinitely without further notice to you.
