We are continually assessing our own performance as a quality professional supplies service and we want to continually improve our service. For these reasons we may also use some of your data (suitably anonymised) for scientific or historical research, service improvement and statistical purposes.

Our ‘Lawful bases’ for processing your data under the Data Protection Act 2018 (the DPA)

The above sections explained, in plain English, what data may be collected from you and how we use it. This section, in a sense, repeats that but puts it in terms that are more directly related to the legal wording of the DPA which requires us to make clear what are our ‘lawful bases’ for processing your data.

They are as follows:

Under Article 6 of the GDPR:

  1. Contract – to fulfil contractual obligations (e.g. invoicing, payment and refund processing) or provide pre-contractual information (e.g. to provide quotes)
  2. Legal Obligation – to fulfil our obligations in relation to the law (e.g. to comply with Court orders) and professional obligations.
  3. Legitimate interests of ourselves or people and companies we work with to provide a service to you. (This means we may process some of the data we hold for the purposes of detecting and preventing fraud, upholding our terms and conditions of service, dealing with complaints, defending ourselves from claims and for our own restricted internal marketing purposes where we feel we would like to inform you of changes to our service or offers we may have. In all cases we will restrict the amount of data we use for these purposes to the minimum necessary to achieve the purpose and we will comply with the law. You have the right to object to your data being used in any marketing activity as well as any other legitimate interest activity.)

Who we share your data with

We will never share your personal information with (or sell it to) advertising or marketing or other listing agencies to use for their own purposes unless you explicitly give us your consent to do this.

In order to fulfil your orders, we nevertheless need to share some of your data with the following data controllers:

PayPal: our online payment service provider

Royal Mail or other delivery company we use to courier your order to you.

In addition:

We may be obliged to share your information to third parties by law (e.g. to comply with a court order).

If you request a password reset, your IP address will be included in the reset email.

Visitor comments may be checked through an automated spam detection service.

In all cases where your information is shared, only the bare minimum that is consistent with adequately achieving the specific limited purpose will be shared.

How long we retain your data

As required by HM Revenue and Customs (HMRC), we retain your order information for a minimum of 5 years.

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognise and approve any follow-up comments automatically instead of holding them in a moderation queue.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

The data we collect and use to provide you with a high quality diagnostic service is your data and you have rights under the DPA in regards to this data.

You have the right to contact the Information Commissioner’s Office (ICO) if you have a concern over the way we handle your data (web site address given below).

You have the right to object to us using your data in certain ways (for example you can object to us using your data for direct marketing purposes).

You also have the right to contact us if you would like a copy of the data we hold about you and you have the right to request we correct any factual inaccuracies in that data.

You have other rights in addition to the above. The law in regards to your rights is subject to some exceptions. Instead of us trying to list all your rights in legally accurate detail in this policy, we feel it is better to direct you to the regulatory body in this regard so you can see the latest and more complete version of your rights with information about how to exercise them. The regulatory body is the Information Commissioner’s Office and their contact details are:
