administer the website and the Tool, including troubleshooting, data analysis, testing, system maintenance, support, and reporting.

The legal basis for using your personal data is our legitimate interest, yours and that of your patients, in providing you with access to and use of the Tool, and such legitimate interests do not override yours.

With whom do we share your personal data?

We will only share your personal data with third parties we use to help us make the Tool available to you. We allow these third parties to process your personal data only if we are convinced that they take appropriate measures to protect it.

We may also share personal data if required by any law enforcement agencies, courts and regulatory bodies to comply with our legal and regulatory obligations.

Your rights: You have the right to:

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.

Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.

Request erasure of your personal data. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.

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 makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. You also have the right to object where we are processing your personal data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your rights and freedoms.

Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data in a number of scenarios; for example, If you want us to establish the data's accuracy or you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.

Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.

Withdraw consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent.

If you would like to exercise any of those rights, please email, call or write to us—see below: ‘How to contact us’.

Keeping your personal data secure:
We have appropriate security measures to prevent personal data from being accidentally lost, or used or accessed unlawfully. We limit access to your personal data to those who have a genuine need to access it.

We also have procedures in place to deal with any suspected data security breach. We will notify you and any applicable regulator of a suspected data security breach where we are legally required to do so.
