Note that if you choose to disable cookies, it is possible that some of our websites’ features may not function properly. Some browsers have “do not track” features that allow you to tell a website not to track you. These features are not all uniform. We do not currently respond to those signals.

2.6     We collect personal information with respect to our recruitment activities. The information we collect depends on how you interact with us. We will use the personal information that you provide or that we collect in this context only for recruiting purposes.


3.1     We will only use your personal data for the purposes for which we collected it, unless we may use it for another reason which is compatible with the original purpose.


4.1     We may share your personal data with selected third-party service providers and other companies within our group that support us in the performance of the activities set out in the table above. We may also share your personal data where it is necessary in order to provide you with services or where we have another legitimate interest in doing so that is not overridden by your interests and fundamental rights. For example, to protect our customers or to operate and to maintain the security of our computer systems.

4.2     Alternatively, we may share your personal data with third parties where required by applicable law, including sharing your personal data with a regulator. We also reserve the right to cooperate with law enforcement authorities and provide information if the release of the personal data is proportionate and necessary in the public interest of the prevention and detection of crime under the particular circumstances.

4.3     We may transfer your personal data outside the European Economic Area (EEA) including to our group companies in Japan, in the USA and other jurisdictions in connection with our operations and as necessary for the performance of any contract that we may have with you. Astex employees may also access personal data from outside the EEA using our IT systems. If we do so, we will ensure that your personal data receives an adequate level of protection and is treated in a way that is consistent with EU and UK laws on data protection.

4.4     We may also share your personal data with other third parties, for example with service providers (such as payment services providers, credit reference agencies, IT solution providers and any of our suppliers and sub-contractors who process data on our behalf in order to assist us with our business activities) or in the context of the possible sale or restructuring of the business.

4.5     We require all our third-party service providers and all other companies within our group to take appropriate and stringent security measures to protect your personal data in line with our policies. When the Data Protection Laws apply and these third parties process data on our behalf, we only permit them to process your personal data for specified purposes in accordance with our instructions. We will also enter into written contracts with such third parties imposing such appropriate security standards on them.


5.1     Some of our third-party service providers may host or otherwise process personal data on Astex’s behalf outside the EEA. In addition to the controls in relation to sharing your information (please see above), we will ensure that any such data sharing is either: (i) to a country for which the European Commission has issued an adequacy decision confirming that the country offers an appropriate level of personal data protection; or (ii) is otherwise subject to appropriate controls such as the Standard Contractual Clauses adopted by the EU Commission.

5.2     We will only retain your personal data for as long as is necessary to fulfil the purposes for which we collected it, including for the purposes of satisfying any legal, accounting or reporting obligations, and in accordance with our internal records retention and management policies.


6.1     We do not knowingly collect information from children under the age of 16. If you become aware that your child or any child under your care has provided us with information without your consent, please contact us (see contact details below in paragraph 12).

6.2     If we learn that an under-13 user has volunteered personally identifiable information on the site, we will delete such information from our active databases.


7.1     All information that you provide to us is stored on secure servers.

7.2     The transmission of information via the internet is not completely secure. Although we will do our best to protect your personal data, we cannot guarantee the security of the information transmitted to our site and you acknowledge that any transmission is at your own risk. Once we have received your information, we will use appropriate procedures and security features to try to prevent unauthorised access or inadvertent disclosure.


8.1     As a data subject, you have the legal right (subject to certain conditions) to:

(a)     Request access to your personal data (commonly known as a ‘data subject access request’). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.

(b)     Request correction or erasure of your personal data (unless we have the legal right to retain it). This right also applies where you have exercised your right to object to processing (see below).

(c)     Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which entitles you to object to processing on this ground. You also have the right to object where we are processing your personal data for direct marketing purposes.

(d)     Request the restriction of processing of your personal data. This enables you to ask us to suspend the processing of personal data about you, for example if you want us to establish its accuracy or the reason for processing it.

(e)     Request the transfer of your personal data to you or another party.

(f)     Withdraw your consent to processing, more details of which are given in paragraph 9.6 below.

8.2     You should be aware that if you ask us to stop processing your personal data in a certain way or to erase your personal data, and processing that data is necessary in order for us to provide services to you, then we may be unable to provide those services. Similarly, your preferences and choices in relation to our website may mean that some or all of the website functionality becomes unavailable to you. This does not affect your right to object to direct marketing, which can be exercised at any time without restriction.

8.3     If you want to review, verify, correct or request erasure of your personal data, object to the processing of your personal data, or request that we transfer a copy of your personal data to another party, please contact us (see contact details in paragraph 12).

8.4     You will not normally have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request for access is clearly unfounded or excessive. Alternatively, we may refuse to comply with the request in such circumstances.

8.5     We may need to request specific information from you to help us confirm your identity and ensure your right to access the information (or to exercise any of your other rights). This is another appropriate security measure to ensure that personal data is not disclosed to any person who has no right to receive it.

8.6     In the limited circumstances where our collection, processing and transfer of your personal data is based upon consent, you have the right to withdraw your consent for that specific processing at any time. To withdraw your consent, please contact us (see contact details in paragraph 13), and once we have received notification that you have withdrawn your consent, we will no longer process your information for the purpose or purposes you originally agreed to, unless we have another legitimate basis for doing so in law.


9.1     We would like to send you information by email about us and other companies in our group which may be of interest to you (including, for example press releases).

9.2     You have the right at any time to stop us from contacting you for marketing purposes or giving your information to other members of our group. If you no longer wish to be contacted for marketing purposes, you can unsubscribe by using the “unsubscribe” link at the bottom of our marketing messages.
