Personal Data Automatically Collected

We, and our third-party partners, automatically collect information you provide to us and information about how you access and use our products and services when you engage with us. We typically collect this information through the use of a variety of our own and our third-party partners’ automatic data collection technologies, including (i) cookies or small data files that are stored on an individual’s computer and (ii) other, related technologies, such as web beacons, pixels, embedded scripts, mobile SDKs, location-identifying technologies and logging technologies. Information we collect automatically about you may be combined with other personal information we collect directly from you or receive from other sources.

We, and our third-party partners, use automatic data collection technologies to automatically collect the following data when you use our services or otherwise engage with us:

Information About Your Device and Network, including the device type, manufacturer, and model, operating system, IP address, browser type, Internet service provider, and unique identifiers associated with you, your device, or your network (including, for example, a persistent device identifier or advertising ID). We employ third-party technologies designed to allow us to recognize when two or more devices are likely being used by the same individual and may leverage these technologies (where permitted) to link information collected from different devices.
Information About the Way Individuals Use Our Services and Interact With Us, including the site from which you came, the site to which you are going when you leave our services, how frequently you access our services, whether you open emails or click the links contained in emails, whether you access our services from multiple devices, and other browsing behavior and actions you take on our services (such as the pages you visit, the content you view, videos you watch, the communications you have through our services, and the content, links and ads you interact with). We employ third-party technologies designed to allow us to collect detailed information about browsing behavior and actions that you take on our services, which may record your mouse movements, scrolling, clicks, and keystroke activity on our services and other browsing, search or purchasing behavior.

All of the information collected automatically through these tools allows us to improve your customer experience. For example, we may use this information to enhance and personalize your user experience, to monitor and improve our products and services, to offer communications features such as live and automated chat, and to improve the effectiveness of our products, services, offers, advertising, communications and customer service.

Single Sign-On: We may provide you the ability to log in to our services through certain third-party accounts you maintain. When you use these single sign-on protocols to access our services, we do not receive your login credentials for the relevant third-party service. Instead, we receive tokens from the single sign-on protocol to help identify you in our system (such as by your username) and confirm you successfully authenticated through the single sign-on protocol. This information allows us to more easily provide you access to our products and services.
Mobile Sign-On: We may provide you the ability to log in to our mobile applications or authenticate yourself using facial, fingerprint, or other biometric recognition technology available through your mobile device. If you choose to utilize these login features, information about your facial geometry, your fingerprint, or other biometric information will be collected by your mobile device for authentication purposes. We do not store or have access to this biometric information. Instead, your mobile device will perform the biometric authentication process and only let us know whether the authentication was successful. If the authentication was successful, you will be able to access the applicable mobile application or feature without separately providing your credentials. For more details, please refer to the biometric authentication guides offered by your device provider.
Other Customers: We may receive your personal data from our other customers. For example, a customer may provide us with your contact information as a part of a referral.

Where we have your consent for the processing of your personal data (e.g., when you opt in to receive certain types of marketing communications from us), you may withdraw your consent by following the instructions provided when your consent was requested or by contacting us as set forth in the Contact Us section below.

Automatic Data Collection Preferences

You may be able to utilize third-party tools and features to restrict our use of automatic data collection technologies. For example, (i) most browsers allow you to change browser settings to limit automatic data collection technologies on websites, (ii) most email providers allow you to prevent the automatic downloading of images in emails that may contain automatic data collection technologies, and (iii) many devices allow you to change your device settings to limit automatic data collection technologies for device applications. Please note that blocking automatic data collection technologies through third-party tools and features may negatively impact your experience using our services, as some features and offerings may not work properly or at all. Depending on the third-party tool or feature you use, you may not be able to block all automatic data collection technologies or you may need to update your preferences on multiple devices or browsers. We do not have any control over these third-party tools and features and are not responsible if they do not function as intended.

Targeted Advertising Preferences

We engage third parties to help us facilitate targeted advertising designed to show you personalized ads based on predictions of your preferences and interests developed using personal data we maintain and personal data our third-party partners obtain from your activity over time and across nonaffiliated websites and other services. The data we and our third-party partners use for purposes of facilitating targeted advertising, as well as to provide advertising-related services such as reporting, attribution, analytics, and market research, are primarily collected through the use of a variety of automatic data collection technologies, including cookies, web beacons, pixels, embedded scripts, mobile SDKs, location-identifying technologies and logging technologies. We may share a common account identifier (such as a hashed email address or user ID) with our third-party advertising partners to help link the personal data we and our third-party partners collect to the same person, or otherwise target advertising to an individual on a third-party website or platform.

In addition to taking the steps set forth in the Automatic Data Collection Preferences section above, you may be able to further exercise control over the advertisements that you see by leveraging one or more targeted advertising opt-out programs. For example:

Device-Specific Opt-Out Programs: Certain devices provide individuals the option to turn off targeted advertising for the entire device (such as Apple devices through their App Tracking Transparency framework or Android devices through their opt out of ads personalization feature). Please refer to your device manufacturer’s user guides for additional information about implementing any available device-specific targeted advertising opt-outs.
Digital Advertising Alliance: The Digital Advertising Alliance allows individuals to opt out of receiving online interest-based targeted advertisements from companies that participate in their program. Please follow the instructions at https://optout.aboutads.info/?c=2&lang=EN for browser-based advertising and https://www.youradchoices.com/appchoices for app-based advertising to opt out of targeted advertising carried out by our third-party partners and other third parties that participate in the Digital Advertising Alliance’s self-regulatory program.
Network Advertising Initiative: The Network Advertising Initiative similarly allows individuals to opt out of receiving online interest-based targeted advertisements from companies that participate in their program. Please follow the instructions at https://optout.networkadvertising.org/?c=1 to opt out of browser-based targeted advertising carried out by our third-party partners and other third parties that participate in the Network Advertising Initiative’s self-regulatory program.
Platform-Specific Opt-Out Programs: Certain third-party platforms provide individuals the option to turn off targeted advertising for the entire platform (such as certain social media platforms). Please refer to your platform provider’s user guides for additional information about implementing any available platform-specific targeted advertising opt-outs.

Please note that when you opt out of receiving interest-based advertisements through one of these programs, this does not mean you will no longer see advertisements from us or on our services. Instead, it means that the online ads you do see from relevant program participants should not be based on your interests. We are not responsible for the effectiveness of, or compliance with, any third parties’ opt-out options or programs or the accuracy of their statements regarding their programs. In addition, program participants may still use automatic data collection technologies to collect information about your use of our services, including for analytics and fraud prevention as well as any other purpose permitted under the applicable advertising industry program.

Modifying or Deleting Your Personal Data

If you have any questions about reviewing, modifying, or deleting your personal data, you can contact us directly at admin@viennaresearch.com. We may not be able to modify or delete your personal data in all circumstances.

Partner-Specific Preferences

Certain of our third-party providers and partners offer additional ways that you may exercise control over your personal data, or automatically impose limitations on the way we can use personal data in connection with the services they provide:

Device-Specific / Platform-Specific Preferences: The device and/or platform you use to interact with us (such as you mobile device or social media provider), may provide you additional choices with regard to the data you choose to share with us. For example, many mobile devices allow you to change your device permissions to prevent our products and services from accessing certain types of information from your device (such as your contact lists or precise geolocation data), and many social media platforms allow you to change your platform permissions to prevent integrated products and services from accessing certain types of information connected with your profile. Please refer to your device or platform provider’s user guides for additional information about implementing any available platform-specific targeted advertising opt-outs.
Google Analytics: Google Analytics allows us to better understand how our customers interact with our services. For information on how Google Analytics collects and processes data, as well as how you can control information sent to Google, review Google's website here: www.google.com/policies/privacy/partners/. You can learn about Google Analytics’ currently available opt-outs, including the Google Analytics Browser Add-On here: https://tools.google.com/dlpage/gaoptout/. We may also utilize certain forms of display advertising and other advanced features through Google Analytics. These features enable us to use first-party cookies (such as the Google Analytics cookie) and third-party cookies (such as the DoubleClick advertising cookie) or other third-party cookies together to inform, optimize, and display ads based on your past visits to our services. You may control your advertising preferences or opt-out of certain Google advertising products by visiting the Google Ads Preferences Manager, currently available at https://myadcenter.google.com/?ref=help-center.

Children’s Personal Data

Our services are not directed to, and we do not intend to, or knowingly, collect or solicit personal data from children under the age of 18. If an individual is under the age of 18, they should not use our services or otherwise provide us with any personal data either directly or by other means. If a child under the age of 18 has provided personal data to us, we encourage the child’s parent or guardian to contact us to request that we remove the personal data from our systems. If we learn that any personal data we collect has been provided by a child under the age of 18, we will promptly delete that personal data.

Security of Personal Data

We have implemented reasonable physical, technical, and organizational safeguards that are designed to protect your personal data. However, despite these controls, we cannot completely ensure or warrant the security of your personal data.

Retention of Personal Data

We will usually retain the personal data we collect about you for no longer than reasonably necessary to fulfil the purposes for which it was collected, and in accordance with our legitimate business interests and applicable law. However, if necessary, we may retain personal data for longer periods of time as required under applicable law or as needed to resolve disputes or protect our legal rights.

To determine the appropriate duration of the retention of personal data, we consider the amount, nature, and sensitivity of the personal data, the potential risk of harm from unauthorized use or disclosure of personal data and if we can attain our objectives by other means, as well as our legal, regulatory, tax, accounting, and other applicable obligations.

Once retention of the personal data is no longer reasonably necessary for the purposes outlined above, we will either delete or deidentify the personal data or, if that is not possible (for example, because personal data has been stored in backup archives), we will securely store the personal data and isolate it from further active processing until deletion or deidentification is possible.

Third-Party Websites and Services

Our services may include links to third-party websites, plug-ins, applications and other services. Except where we post, link to or expressly adopt or refer to this Privacy Notice, this Privacy Notice does not apply to any personal data practices of third parties.
