The Sia Privacy Policy

Your right to privacy is very important. We recognize that when you choose to provide us with personal information (defined as information that identifies, relates to, describes, or can be associated with you), you trust us to act in a responsible manner. We make every effort to preserve user privacy. This Privacy Policy describes the personal information that the Sia Foundation (the “Foundation,” “us,” “we” or “our”) collects through your interactions with the Sia website (sia.tech) (the “Website”), and how we collect, use, safeguard and disclose that information. By using this Website, you acknowledge and agree that you have read and understand the data practices described in this Privacy Policy.

When you interact with an email we send you, we may also collect information about your interactions with the email through cookies and similar tracking technologies. This information is used to improve the content of our Website, and any web browser cookies we deploy are only used to collect aggregate statistics that help us measure the effectiveness of our Website content as well as our navigational design. We do not use cookies for targeted advertising. Please see the section “Cookies and Online Interactions” for more information about the cookies that we use and how we use them.

To manage our business operations, perform our obligations and exercise our rights under any agreement that you have with us.
We use personal information to comply with our legal or regulatory obligations, to establish or exercise our rights, and to defend against a legal claim.
We use personal information to detect, investigate, prevent, or take action regarding possible malicious, deceptive, fraudulent, or illegal activity, including fraudulent transactions, attempts to manipulate or violate our policies, procedures, and terms and conditions, security incidents, and harm to the rights, property, or safety of the Foundation and our users, customers, employees, or others.
For other purposes with your consent, or as otherwise permitted or required by applicable law.

Disclosure of personal information

We may disclose your personal information in the following situations, as permitted by applicable law.

Service Providers. We work with third parties that provide services on our behalf. Such services may include website hosting. We may disclose personal information to these third parties for the purpose of enabling them to provide these services.
Affiliated Companies. We may disclose such personal information to subsidiaries, affiliates or strategic partners as needed to provide our products and services and generally as necessary in the administration of a global organization.
Consent. We may disclose personal information in accordance with any consent you provide.
Government agencies, regulators, and professional advisors. We may disclose personal information if we are required to do so by law or pursuant to legal process, in response to a request from government officials or law enforcement authorities, as necessary or appropriate in connection with an investigation of illegal activity, to comply with our legal obligations, and defend our legal interests.
Certain Transactions. We may disclose or transfer personal information to third parties who acquire all or a portion of our business, whether such acquisition is by way of merger, consolidation, or purchase of all or a portion of our assets, or in connection with any bankruptcy or reorganization proceeding brought by or against us. We have not disclosed your personal information for direct marketing purposes in the preceding twelve (12) months.

Legal Basis For Collecting and Using Your Personal Information

The Foundation relies on the following legal grounds for the collection, processing, and use of your personal information:

As necessary to provide a service or perform a transaction (such as when we respond to your requests);
Consent (where you have provided consent as appropriate under applicable law, such as for direct marketing or certain cookies);
As necessary for legitimate interests (such as when we act to maintain our global business generally, including maintaining the safety and security of the Site); and
Compliance with legal obligations, particularly in the area of labor and employment law, social security and protection law, data protection law, tax law, and corporate compliance laws. The provision of your personal information is partly a statutory requirement and partly a contractual obligation.

Security

We take appropriate steps to protect your privacy and implement reasonable security measures to protect your personal information in storage and in transmission. However, no method of transmitting or storing data is completely secure. As a result, although we strive to protect personal information about you, we cannot guarantee the security of any information you transmit to us through or in connection with the Website. If you have reason to believe that personal information is no longer secure, please notify us immediately by contacting us in accordance with the last section below. In the event of a breach that we are required by law to inform you of, we may notify you electronically, in writing, or by telephone, if permitted to do so by law.

External Links

Our Website may provide links to third-party sites. Since we do not control those websites, we encourage you to review the privacy policies of these third-party websites. We have no control over third-party sites and are not responsible or liable for the content, privacy practices, or use of any sites that are not affiliated with the Foundation.

Data Retention

We retain information about you and your use of our Website for as long as is needed to fulfill our legitimate business purposes outlined in this Privacy Policy. The specific periods for which we keep information about you vary depending on the nature of the information, why we need it, and whether the personal information is de-identified. We also consider the minimum necessary retention period prescribed by applicable laws, recommended by industry standards, and stated in contracts and other legal obligations.

Children’s Privacy

Our Website is not intended for persons under 13 years of age. If we learn that we have collected personal information from persons under 13 through our Website, we will take appropriate steps to delete this information.

Data Transfers

The Foundation is headquartered in the United States, and we may have operations, entities, and service providers both in the United States and throughout the world. As such, we and our service providers may transfer your personal information to, or access it in, jurisdictions that may not provide equivalent levels of data protection as your home jurisdiction. We will take steps to ensure that your personal information receives an adequate level of protection in the jurisdictions in which we process it. If you are located in the European Economic Area, Switzerland, or the UK, we provide adequate protection for the transfer of personal information to countries outside of these areas, such as through the use of authorized EU Standard Contractual Clauses, the UK Standard Contractual Clauses, or the UK Addendum to the EU Standard Contractual Clauses. Depending on your location, you may have the right to request a copy of such appropriate safeguards by contacting us as set out at the end of this Privacy Policy.

Cookies and Online Interactions

We may use various technologies to collect and store information, including cookies. Cookies are small bits of data cached or stored on your computer or mobile device based on your Internet activity. This section describes how we may use cookies and other data-collection technologies and how you can manage cookies that are not required to operate our sites and mobile applications.

We differentiate between cookies that are essential for the technical features of the Website and analytics cookies. We do not use advertising cookies.

Essential Cookies

These are cookies that the Website needs in order to function, and that enable you to move around and use the Website. Without these essential cookies, the Website will not perform as smoothly for you as we would like it to and we may not be able to provide the Website or certain features you request. We currently do not use essential cookies.

Analytics Cookies

Analytics cookies allow website operators to understand more about how many visitors the website has, how many times they visit and how many times they view specific pages within the website. Although analytics cookies allow website operators to gather specific information about the pages that are visited and whether a visitor has visited the website multiple times, they cannot be used to find out details such as an individual’s name or address. We do not use analytics cookies on our Website, but instead deploy privacy-friendly embedded scripts called Fathom Analytics and Cloudflare Insights to perform website analytics. You can find out more about Fathom Analytics here and Cloudflare Insights here.

Most web browsers automatically accept cookies, but you can usually change your browser settings to prevent this. If you disable cookies, your ability to use some features of the Website may be limited. For mobile devices, you may be able to manage certain cookies using your built-in mobile device settings and controls, or the settings within your mobile application, where applicable. Choices are browser- and/or device-specific. If you clear your cookies from your browser on any of your devices, your choices will need to be reset. You should check how to do this on your device(s) and operating systems.

Your Rights

You may have certain rights regarding your personal information. The rights available to you depend on our reason for processing your personal information and the requirements of applicable law (i.e., whether you are in the European Union, or the UK). Specifically, you may have the following rights:

Right to access: You may have the right to obtain from us confirmation as to whether personal information concerning you is being processed, and, where that is the case, to request access to the personal information.
Right to data portability: You may have the right to request that we transfer the personal information we have collected about you to another organization, or directly to you, in a structured, commonly used, and machine-readable format, under certain conditions.
Right to rectification (right to correct inaccurate information): You may have the right to request that we correct any personal information about you that is inaccurate. Depending on the purpose of the processing, you also have the right to request that we complete the personal information we hold about you where you believe it is incomplete, including by means of providing a supplementary statement.
Right to erasure (right to be forgotten): You may have the right to request that we erase your personal information, under certain conditions.
Right to restrict processing: You may have the right to request that we restrict the processing of your personal information, under certain conditions. In such case, the respective data will be marked and may only be processed by us for certain purposes.
Right to object to processing: You may have the right to object to our processing of your personal information, under certain conditions, and we can be required to no longer process your personal information. Such right to object may especially apply if we collect and process your personal information through automated decision making, such as profiling, to better understand your interests in our products and services or for direct marketing. If you have a right to object and you exercise this right, your personal information will no longer be processed by us for such purposes. Such a right to object may, in particular, not exist if the processing of your personal information is necessary to take steps prior to entering into a contract or to perform a contract already concluded.
Right to withdraw consent: Where we rely on your consent to process your personal information, you have the right to withdraw that consent at any time with future effect. Such a withdrawal will not affect the lawfulness of the processing prior to the consent withdrawal.

Updates to this Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to our practices, technology, legal requirements, and other factors. When changes are made to this Privacy Policy, they will become effective immediately upon posting. We encourage you to review this Privacy Policy periodically for the latest information on our information processing practices. To the extent that our Privacy Policy changes in a material way, the Privacy Policy that was in place at the time that you submitted personal information to us will generally govern that information unless we receive your consent (express or implied) to the new Privacy Policy where and as required by applicable law.
