California residents: If you are a California resident, please read the below in addition to this Privacy Policy for information about your personal information and privacy rights.

This Privacy Policy describes how Sierra CP Engineering Limited, “Sierra CP”, and our subsidiaries and other affiliates (“Company,” “we“, “us” or “our“) may collect and process personal information that through our digital or online properties or services that link to this Privacy Policy (collectively, the “Service”)). Not all data collections or processing described herein may apply to you or your data. We may provide additional or supplemental privacy policies to individuals for specific products or services that we offer at the time we collect personal information.

The Company delivers bespoke testing equipment. This Privacy Policy does not apply to information that we process on behalf of our business customers (such as businesses and other organizations) while providing our services to them.

Our websites, products and services are designed for enterprise customers and their representatives. We do not offer products or services directly to individuals for their personal, family or household purposes. Accordingly, we treat all personal information we collect as pertaining to individuals in their capacities as representatives of the relevant enterprise and not their individual capacities.

Your privacy rights. As a California resident, you have the following rights under the CCPA:

  • Right to know.You can request information about the categories of personal information that we have collected; the categories of sources from which we collected personal information; the business or commercial purpose for collecting, sharing and/or selling personal information; the categories of any personal information that we sold or disclosed for a business purpose; and the categories of any third parties with whom personal information was sold, shared or disclosed for a business purpose.
  • Right to access. You can request a copy of personal information that we have collected about you.
  • Right to deletion. You can request that we delete personal information that we collected from you.
  • Right to opt-out. If we “sell” or “share” your personal information as defined by the CCPA, you can opt-out of those disclosures.

  • Nondiscrimination. You are entitled to exercise the rights described above free from discrimination as prohibited by the CCPA.

How to exercise your rights. You may submit requests to exercise your right to information/know, access, appeal, correction, or deletion by using the How to contact us section above or at https://www.sierra-cp.com/support. The rights described above are not absolute, and, in certain cases, we may decline your request as permitted by law or where the laws in your state do not afford you these rights.  We cannot process your request if you do not provide us with sufficient detail to allow us to understand and respond to it.  You can ask to appeal any denial of a request in the same manner through which you may submit one.

Verification of identity; authorized agents.  We may need to verify your identity to process your information/know, access, deletion, and correction requests, and we reserve the right to confirm your residency.

  • We do not to attempt to reidentify deidentified information derived from personal information, except for the purpose of testing whether our deidentification processes comply with applicable law.

Notice to users in Europe and other countries outside the US


Where this Notice to users in Europe and other countries outside the US applies. The information provided in this “Notice to users in Europe and other countries outside the US” section applies only where (i) we are processing the personal information of individuals located in the EEA, the UK (EEA and UK jurisdictions are together referred to as “Europe”), or other country as a controller, and (ii) the laws related to the processing of personal information of such jurisdiction apply directly to us. For the avoidance of doubt, this section does not constitute our submission to the jurisdiction of any such laws around the world and this section only applies to the extent the data protection or data privacy laws of a particular jurisdiction outside of the United States apply directly to our processing of your personal information.

Personal information. References to “personal information” in this Privacy Policy should be understood to include a reference to “personal data” (as defined in the GDPR or applicable law) – i.e., information about individuals from which they are either directly identified or can be identified.

Controller. The Company is the controller in respect of the processing of your personal information covered by this Privacy Policy for purposes of European or other data protection legislation (i.e., the EU GDPR and the so-called ‘UK GDPR’ (as and where applicable, the “GDPR”)). See the How to contact us section above for our contact details.

Our legal bases for processing

In respect of each of the purposes for which we use your personal information, the GDPR requires us to ensure that we have a “legal basis” for that use.
Our legal bases for processing your personal information described in this Privacy Policy are listed below.

  • Where we need to process your personal information to deliver our Services to you (including our Site) (“Contractual Necessity”).
  • Where it is necessary for our legitimate interests and your interests and fundamental rights do not override those interests (“Legitimate Interests”). More detail about the specific legitimate interests pursued in respect of each Purpose we use your personal information for is set out in the table below.
  • Where we need to comply with a legal or regulatory obligation (“Compliance with Law”).
  • Where we have your specific consent to carry out the processing for the Purpose in question (“Consent”).

We have set out below, in a table format, the legal bases we rely on in respect of the relevant Purposes for which we use your personal information – for more information on these Purposes and the data types involved, see How we use your personal information above.

Compliance and protectionAny and all data types relevant in the circumstancesCompliance with Law.Legitimate interest. Where Compliance with Law is not applicable, we and any relevant third parties have a legitimate interest in participating in, supporting, and following legal process and requests, including through co-operation with authorities. We and any relevant third parties may also have a legitimate interest of ensuring the protection, maintenance, and enforcement of our and their rights, property, and/or safety.
Further uses Any and all data types relevant in the circumstancesThe original legal basis relied upon, if the relevant further use is compatible with the initial purpose for which the Personal Information was collected.Consent, if the relevant further use is not compatible with the initial purpose for which the personal information was collected.


We retain personal information for as long as necessary to fulfil the purposes for which we collected it, including for the purposes of satisfying any legal, accounting, or reporting requirements, to establish or defend legal claims, or for compliance and protection purposes.

To determine the appropriate retention period for personal information, we consider the amount, nature, and sensitivity of the personal information, the potential risk of harm from unauthorized use or disclosure of your personal information, the purposes for which we process your personal information and whether we can achieve those purposes through other means, and the applicable legal requirements.

When we no longer require the personal information, we have collected about you, we will either delete or anonymize it or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible. If we anonymize your personal information (so that it can no longer be associated with you), we may use this information indefinitely without further notice to you.

Other information

No obligation to provide personal information. You do not have to provide personal information to us. However where we need to process your personal information either to comply with applicable law or to deliver our Services to you, and you fail to provide that personal information when requested, we may not be able to provide some or all of our Services to you. We will notify you if this is the case at the time.

No sensitive personal information. We ask that you not provide us with any sensitive personal information (e.g., social security numbers, information related to racial or ethnic origin, political opinions, religion or other beliefs, health, biometrics or genetic characteristics, criminal background or trade union membership) on or through the Services, or otherwise to us. If you provide us with any sensitive personal information to us when you use the Services, you must consent to our processing and use of such sensitive personal information in accordance with this Privacy Policy. If you do not consent to our processing and use of such sensitive personal information, you must not submit such sensitive personal information through our Services.

No automated decision-making and profiling. As part of the Services, we do not engage in automated decision-making and/or profiling, which produces legal or similarly significant effects. We will let you know if that changes by updating this Privacy Policy.

Security. We have put in place procedures designed to deal with breaches of personal information. In the event of such breaches, we have procedures in place to work with applicable regulators. In addition, in certain circumstances (including where we are legally required to do so), we may notify you of breaches affecting your personal information.

Your rights

General. Applicable data protection laws may give you certain rights regarding your personal information. If you are located in Europe or other countries outside the US where such rights apply, you may ask us to take any of the following actions in relation to your personal information that we hold:

  • Access. Provide you with information about our processing of your personal information and give you access to your personal information.
  • Correct. Update or correct inaccuracies in your personal information.
  • Delete. Delete your personal information where there is no lawful reason for us continuing to store or process it, where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase your personal information to comply with local law. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons that will be notified to you, if applicable, at the time of your request.
  • Portability. Port a machine-readable copy of your personal information to you or a third party of your choice, in certain circumstances. Note that this right only applies to automated information for which you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Restrict. Restrict the processing of your personal information, if, (i) you want us to establish the personal information’s accuracy; (ii) where our use of the personal information is unlawful but you do not want us to erase it; (iii) where you need us to hold the personal information even if we no longer require it as you need it to establish, exercise or defend legal claims; or (iv) you have objected to our use of your personal information but we need to verify whether we have overriding legitimate grounds to use.
  • Object. Object to our processing of your personal information where we are relying on legitimate interests (or those of a third party) and there is something about your particular situation that makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedom – you also have the right to object where we are processing your personal information for direct marketing purposes.
  • Withdraw Consent. When we use your personal information based on your consent, you have the right to withdraw that consent at any time. This will not affect the lawfulness of any processing carried out before you withdraw your consent.

Exercising These Rights. You may submit these requests by using the How to contact us section above. We may request specific information from you to help us confirm your identity and process your request. Whether or not we are required to fulfill any request you make will depend on a number of factors (e.g., why and how we are processing your personal information), if we reject any request you may make (whether in whole or in part) we will let you know our grounds for doing so at the time, subject to any legal restrictions.  Typically, you will not have to pay a fee to exercise your rights; however, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. We try to respond to all legitimate requests within a month. It may take us longer than a month if your request is particularly complex or if you have made a number of requests; in this case, we will notify you and keep you updated.

Your Right to Lodge a Complaint with your Supervisory Authority. In addition to your rights outlined above, if you are not satisfied with our response to a request you make, or how we process your personal information, you can make a complaint to the data protection regulator in your habitual place of residence.

Data Processing outside of your home country 

We are an international company and many of our service providers, advisers, partners or other recipients of data are also based in the US and elsewhere around the world. This means that, if you use the Services, your personal information may be accessed and processed in the US or elsewhere around the world.

It is important to note that the recipient jurisdiction may not be subject to an ‘adequacy decision’ under applicable laws (e.g., GDPR) – basically, this means that the recipient jurisdiction’s legal regime is not considered by relevant legal bodies to provide an adequate level of protection for personal information, which is equivalent to that provided by your home jurisdiction (e.g., Europe) laws.

Where we share your personal information with third parties who are based outside your home country, we try to ensure a similar degree of protection is afforded to it in accordance with applicable privacy laws by making sure one of the following mechanisms is implemented:

  • Transfers to territories with an adequacy decision. We may transfer your personal information to countries or territories whose laws have been deemed to provide an adequate level of protection for personal information by the relevant legal authority (e.g., the European Commission or UK Government).
  • Transfers to territories without an adequacy decision.
  • We may transfer your personal information to countries or territories whose laws have not been deemed to provide such an adequate level of protection (e.g., the US, see above).
  • However, in these cases:
    • we may use specific appropriate safeguards, which are designed to give personal information effectively the same protection it has in your home country – for example, standard-form contracts approved by relevant authorise for this purpose; or
    • in limited circumstances, we may rely on an exception, or ‘derogation’, which permits us to transfer your personal information to such country despite the absence of an ‘adequacy decision’ or ‘appropriate safeguards’ – for example, reliance on your explicit consent to that transfer.

You may contact us if you want further information on the specific mechanism used by us when transferring your personal information out of your home country.
