6. Data Subject Rights.
If you are in the European Economic Area (EEA) you have the following rights:

Access. Subject to certain exceptions, you have the right to request a copy of the Personal Data we are processing about you, which we will provide to you in electronic form. At our discretion we may require you to prove your identity before providing the requested information.
Rectification. You have the right to require that any incomplete or inaccurate Personal Data that we process about you is amended.
Deletion. You have the right to request that we delete Personal Data that we process about you, unless we are required to retain such data in order to comply with a legal obligation or to establish, exercise or defend legal claims.
Restriction. You have the right to request that we restrict our processing of your Personal Data where:
you believe such data to be inaccurate;
our processing is unlawful; or
we no longer need to process such data for a particular purpose, but where we are not able to delete the data due to a legal or other obligation or because you do not want us to delete it.
Portability. You have the right to request that we transmit the Personal Data we hold with respect to you to another data controller, where this is:
personal information which you have provided to us; and
we are processing that data on the basis of your consent or in order to perform our obligations under contract to you (such as to provide legal services).
Objection. Where the legal justification for our processing of your Personal Data is our legitimate interest, you have the right to object to such processing on grounds relating to your particular situation. We will abide by your request unless we have compelling legitimate grounds for the processing which override your interests and rights, or if we need to continue to process the data for the establishment, exercise or defence of a legal claim.
Withdrawing Consent. If you have consented to our processing of your Personal Data, you have the right to withdraw your consent at any time, free of charge. This includes cases where you wish to opt out from marketing messages that you receive from us.
If you are in the EEA you also have the right to lodge a complaint with the local data protection authority if you believe that we have not complied with applicable data protection laws. Access a list of local data protection authorities in EEA countries.

7. Information Security.
We maintain reasonable technical and organizational measures to protect Personal Data from loss, misuse, alteration, or unintentional destruction. However, no security measure can guarantee against compromise.

8. Cross-Border Transfers.
We transfer Personal Data to various jurisdictions as necessary for the purposes described above, including to jurisdictions that may not provide the same level of data protection as your home country. We provide appropriate protections for cross-border transfers as required by applicable law for international data transfers. With respect to transfers originating from the European Economic Area (“EEA“), we implement standard contractual clauses approved by the European Commission, and other appropriate solutions to address cross-border transfers as required by applicable law. Where required by such laws, you may request a copy of the suitable mechanisms we have in place by contacting us as detailed below.

9. Other Issues
(i) What is the legal basis of processing?

Some jurisdictions require an explanation of the legal basis for collecting and processing Personal Data. We have several different legal grounds on which we collect and process Personal Data, including: (i) as necessary to perform a transaction (such as when we respond to your requests); (ii) as necessary to comply with a legal obligation (such as when we use Personal Data for recordkeeping to substantiate tax liability); (iii) consent (where you have provided consent as appropriate under applicable law, such as for direct marketing or certain cookies); and (iv) necessary for legitimate interests (such as when we act to maintain our business generally). With respect to legitimate interests, given that we are a B2B company, we typically collect and process limited Personal Data about customer contacts and other individuals acting in their business capacities, as part of our overall effort to reduce the privacy impact on individuals.

(ii) What are the consequences of not providing Personal Data?

You are not required to provide all Personal Data identified in this Privacy Statement to use our website or to interact with us offline, but certain functionality will not be available if you do not provide certain Personal Data. If you do not provide certain Personal Data, we may not be able to respond to your requests, perform a transaction with you, or provide you with marketing that we believe you would find valuable.

(iii) Do we engage in automated decision-making without human intervention?

We do not use automated decision-making without human intervention, including profiling, in a way that produces legal effects concerning you or otherwise significantly affects you.

(iv) Does the website honor do not track (“DNT”) signals sent via browsers?

Given the divergent practices of organizations that offer browsers and the lack of a standard in the marketplace, we do not respond to DNT signals at this time.

(v) How long do we retain Personal Information?

We typically retain Personal Data related to marketing activities for as long as you accept marketing communications from us and upon request, we will securely delete such data in accordance with applicable law. For Personal Data that we collect and process for other purposes, as described above, we typically retain such Personal Data for no longer than the period necessary to fulfill the purposes outlined in this Privacy Statement, and as otherwise needed to address tax, corporate, compliance, employment, litigation, and other legal rights and obligations.

(vi) Are third party websites governed by this Privacy Statement?

This website contains links and references to other websites (e.g., social media buttons) administered by unaffiliated third parties. This Privacy Statement does not apply to such third party websites. When you click a link to visit a third party website, you will be subject to that website’s privacy practices. We encourage you to familiarise yourself with the privacy and security practices of any linked third party websites before providing any Personal Data on those websites.

(vii) How does Darchem handle employee and contractor privacy issues?

Personal Data about our employees and contractors are addressed through internal company policies and procedures, and are outside the scope of this Privacy Statement.

(viii) How will we handle any changes to this Privacy Statement?

We may update this Privacy Statement from time-to-time as our services and privacy practices change, or as required by law. The effective date of our Privacy Statement is posted below, and we encourage you to visit our website periodically to stay informed about our privacy practices. We will post the updated version of the Privacy Statement on our website, and ask for your consent to the changes if legally required.
