Website Analytics and Session Replay

We use analytics and session replay services, that use cookies and other technologies that collect your Personal Information, to assist us with analyzing our Site traffic and site usage to optimize, maintain, and secure our Site and inform subsequent business decisions (including, e.g., advertising). These include, but are not limited to, the following third-party services:

• Microsoft Clarity: We partner with Microsoft Clarity and Microsoft Advertising to capture how you use and interact with our Site through behavioral metrics, heatmaps, and session replay to improve and market our products/services. Site usage data is captured using first and third-party cookies and other tracking technologies to determine the popularity of products/services and online activity.

To learn more about how Google uses data, visit Google’s Privacy Policy and Google’s page on “How Google uses data from sites or apps that use our services.” You may download the Google Analytics Opt-out Browser Add-on for each web browser you use, but this does not prevent the use of other analytics tools. To learn more about Google Analytics cookies, visit Google Analytics Cookie Usage on Websites. Additionally, third parties, including Google (through, for example, our use of Google Analytics Advertising Features, including Dynamic Remarketing), may place and read cookies on your browser, or use web beacons to collect information in connection with ad serving on or through the Site, including for the purposes of showing our ads on sites across the internet. Our partners will collect personal information for personalization of ads and may use first-party cookies or other first-party identifiers and third-party cookies and other third-party identifiers for personalized and non-personalized advertising and measurement. Ad serving may be based on users’ visits to our Site or other websites on the Internet, and your activity may be tracked over time and across websites. For information about how Google collects, shares, and uses data, please visit: Google Privacy & Terms. You can opt out of Google’s use of cookies or device identifiers by visiting the Google Ads Settings web page at: Google Ad Preferences.

• Meta: We use Meta pixels to track user activity on our Site and improve downstream offerings, including interest-based advertising for our services and those of our partners and service providers. We further use the Meta Pixel to analyze user activity on our Site for remarketing and behavioral targeting. The Meta Pixel is triggered when you perform certain activities on the Site and aids us in displaying Facebook ads to Facebook users who have visited our Site, or Facebook users who share certain characteristics with visitors to our Site. Meta and other third parties may use cookies, web beacons, and other storage technologies to collect information from the Site and from other internet websites and use that information for the purposes of targeting ads and providing measurement services. Meta may track your activity over time and across websites. For more information about the data Meta collects, please visit Meta’s privacy policy at: Facebook Privacy Policy. For specific information about Meta Pixel, please visit: Meta Business Help Center. For more information about ad targeting and exercising your choice to opt out of the collection and use of information for ad targeting, please visit: Facebook Help Center, or WebChoices
• TikTok: The Site uses TikTok Business Products that involve TikTok’s access to or storage of information on your device, including but not limited to the TikTok Pixel or other similar tracking technologies (such as access to data using pixels, cookies, APIs, SDKs, etc.) to collect information about how users use the Site.

You can opt out of receiving targeted ads (including ads served using non-cookie technologies) from members of the NAI on the NAI's website, available at:networkadvertisn. You can also visit the Digital Advertising Alliance’s website, available at youradchoices.com, to use its Consumer Choice Tools, or control the use of device identifiers by using your device’s settings.

Interest-Based Advertising 

We may also allow or enable third parties to collect Personal Information to provide their interest-based advertising on behalf of our products and services, or their own. Interest-based advertising occurs when advertisements are shown to you based on information collected from your online interactions over time and across multiple websites, devices, or online services that you visit or use. Some companies may engage in cross-context behavioral advertising to predict your preferences and show you advertisements that are most likely to be of interest or relevant to you. We do not control these third parties’ collection or use of your information for these purposes, or the opt-out options they may individually offer you via their terms, conditions, and privacy policies. If you have any questions about an advertisement or other targeted content, you should contact the responsible provider directly. Examples of the third-party service providers we engage to serve interest-based advertisements include ID5, Criteo, Google Ads (including Google Dynamic Remarketing, Google Signals, and DoubleClick), Meta Ads (including Meta Pixels and Facebook advertising services), LinkedIn marketing solutions (including LinkedIn Analytics), Microsoft advertising, X Advertising, and TikTok Business Products (including TikTok Analytics).

Selling or Sharing Personal Information 

While we do not sell Personal Information in exchange for monetary consideration, we do share Personal Information for other benefits that could be deemed a “sale” or “sharing” under various data protection laws, because they are sometimes broadly defined to include activities such as the delivery of interest-based advertising on websites or allowing third parties to receive certain information, such as cookies, IP address, and/or browsing behavior. We similarly engage in interest-based advertising when we use data about your activities on our Site to serve you ads on websites owned or controlled by third parties. It is in this context that we have provided advertising networks, data analytics providers, social networks, and video sharing platforms with Personal Information such as your IP address, device information, Internet and other electronic network activity information, and geolocation information in the last twelve months.

Cookie Choices – To manage your preferences with respect to these technologies, you can:

• Visit our preferences page or customize your browser settings to refuse all or some browser cookies, or to alert you when websites set or access cookies. If you disable certain cookies, please note that some parts of our Site may not function properly. These settings may be lost and require reconfiguration if you delete your cookies.

•  Block the collection and use of your information by online platforms and ad tech companies for the purpose of serving interest-based advertising by visiting the opt out pages of the self-regulatory programs of which those companies are members: National Advertising Initiative and Digital Advertising Alliance. Please note that even if you opt out of interest-based advertising, you may still see “contextual” ads which are based on the context of what you are looking at on the websites and pages you visit.

•  Review and execute any provider-specific instructions to customize your preferences or opt-out of certain processing, including interest-based advertising, by third-party service providers. For example, to opt-out of this type of advertising by Google, customize your ad preferences, or limit Google’s collection or use of your data, visit Google’s Safety Center and Google’s Ad Settings and follow Google’s personalized ad opt-out instructions. Meta also offers an Ad Preferences center to customize your settings, as well as a Privacy Policy with additional information on how you can exercise your rights.

How Long We Keep Your Personal Information

We retain your information for as long as needed: (i) to conduct business with you; (ii) fulfill the purposes outlined in this Notice; and (iii) to comply with our legal obligations, resolve disputes, and enforce any agreements.

Criteria we will use to determine how long to retain your Personal Information include the nature and length of our business relationship with you, our legal rights, obligations, and retention requirements, and if we have an ongoing business purpose for retaining your Personal Information, such as communicating with you about ongoing or prospective Services you requested.

Links to Third-Party Websites

We are not responsible for the practices employed by any websites or services linked to or from our Site, including the information or content contained within them. We encourage you to investigate and ask questions before disclosing Personal Information to third parties, since any Personal Information disclosed will be handled in accordance with the applicable third party’s privacy policy. In some cases, we offer links to social media platforms (like Facebook, Instagram, LinkedIn, TikTok, X (formerly known as Twitter), and YouTube) that enable you to easily connect with us or share information on social media. Any content you post via these social media pages is subject to the Terms of Use and Privacy Policies for those platforms.

International Use and Cross-Border Data Transfers

If you are visiting our Site, please note that where permitted by applicable law, we may transfer the Personal Information we collect about you to and from the United States and other jurisdictions that may not be deemed to provide the same level of data protection as your home country, as necessary for the purposes set out in this Notice.

How We Protect Personal Information

We have implemented commercially reasonable measures designed to secure your Personal Information from accidental loss and from unauthorized access, use, alteration, and disclosure. Unfortunately, the transmission of information via the internet is not completely secure. Despite these efforts to store Personal Information in a secure environment, we cannot guarantee the security of Personal Information during its transmission or its storage on our systems.

Exercising Your Privacy Rights

Depending on where you live, you may have the following rights with respect to your Personal Information under applicable data protection laws:

• Access – The right to request access to and obtain a copy of any Personal Information we may have about you.
• Deletion – The right to delete your Personal Information that we have collected or obtained, subject to certain exceptions.

We do not collect or process sensitive Personal Information outside of purposes permitted by law (such as section 7027(m) under the California Consumer Privacy Act Regulations), so we do not offer the option to limit its use. We also do not profile you or other individuals in a manner that would result in legal or similarly significant effects, so we do not offer an opt out.
• Objection/Restriction of Processing – The right to object or restrict us from processing your Personal Information in certain circumstances.
• Withdraw Consent – The right to withdraw your consent where we are relying on your consent to process your Personal Information.
• Automated Decision-Making – The right to know when you are subject to automated decision-making, the Personal Information used to render the decision, the principal factors and parameters involved in the decision, and human review or correction of the decision (or its underlying data, where appropriate). You may also have the right to consent or opt out of this automated decision-making, depending on your location.

To exercise any of the privacy rights afforded to you under applicable data protection laws, e-mail us at compliance.us@idorsia.com, or call us at 1- 888-971-7050, option #4. You may also exercise your opt out rights by broadcasting an Opt-Out Preference Signal, such as the Global Privacy Control (GPC). We honor Opt-Out Preference Signals, including GPC. If you choose to use an Opt-Out Preference Signal, you will need to turn it on for each supported browser or browser extension you use.

You will not be discriminated against in any way by virtue of your exercise of the rights listed in this Notice. However, should you withdraw your consent or object to processing of your Personal Information, or if you choose not to provide certain Personal Information, we may be unable to provide some, or all, of our Services to you.

Only you, or an authorized agent that you authorize to act on your behalf, may make a request related to your Personal Information. You may also make a request on behalf of your minor child. We must verify your identity before fulfilling your requests, and if we cannot verify your identity, we may request additional information from you. If you are an authorized agent making a request on behalf of another person, we will also need to verify your identity, which may require proof of your written authorization or evidence of a power of attorney. We endeavor to respond to requests within the time period required by applicable law. If we require more time, we will inform you of the reason and extension period in writing.

We do not charge a fee to process or respond to your requests unless they are excessive or repetitive. If we determine that a request warrants a fee, we will tell you why we made that decision and provide you with a cost estimate before completing your request. We may deny certain requests, or only fulfill some in part, as permitted or required by law. If you are not satisfied with the resolution of your request and you are afforded a right to appeal such decision, you will be notified of our appeal process in our response to your request.

Children’s Privacy

We do not knowingly collect or solicit any Personal Information from children, as defined under applicable law, without verified written parental consent, and we have no actual knowledge of selling such Personal Information of minors under 16 years of age. If we learn that we have collected Personal Information from a child, we will promptly take steps to delete that information. If you believe we might have any information from or about a child, please contact us at compliance.us@idorsia.com.
