What personal data does Stacksync collect and why?

Broad Categories of personal data collected:

The personal data that we may collect about you broadly falls into the following categories of sources:

  • Information that you provide voluntarily Certain parts of our Website may ask you to provide personal data voluntarily: for example, we may ask you to provide your contact details in order to register an account with us, for technical support, to subscribe to marketing communications from us, to register for an event, to access content, and/or to submit inquiries to us. The personal data that you are asked to provide, and the reasons why you are asked to provide it, will be made clear to you at the point we ask you to provide your personal data. If you decide not to provide some information voluntarily, you may still use our Websites though your access to some functionality and areas of our Websites may be restricted.

  • Information that we collect automatically When you visit our Website, we may collect certain information automatically from your device. In some countries, including countries in the European Economic Area, this information may be considered personal data under applicable data protection laws. Specifically, the information we collect automatically may include information like your IP address, device type, unique device identification numbers, browser-type, broad geographic location (e.g. country or city-level location) and other technical information. We may also collect information about how your device has interacted with our Website, including the pages accessed and links clicked. Collecting this information enables us to better understand the visitors who come to our Website, where they come from, and what content on our Website is of interest to them. We use this information for our internal analytics purposes and to improve the quality and relevance of our Website to our visitors. Some of this information may be collected using cookies and similar tracking technology, as explained further under the heading “Cookies and similar tracking technology” below.

  • Information that we obtain from third party sources From time to time, we may receive personal data about you from third-party sources (including, but not limited to, lead generation providers, partners, content syndication providers, third-party enrichment tools, and meeting maker vendors), but only where we have checked that these third parties either have your consent or are otherwise legally permitted or required to disclose your personal data to us. The types of information we collect from third parties include name, contact information, title and or role within your organization, internet activity, company data, and we use the information we receive from these third parties to market our services to you.

Sensitive Personal Data

We may collect sensitive personal data, or special category personal data, from customers as a part of providing our services. We do not use sensitive personal data for any other commercial purpose, we do not sell sensitive personal data, and do not share sensitive personal data for online advertising.

Who does Stacksync share my personal data with?

We may disclose your personal data to the following categories of recipients:

  • to our group companies and third-party services providers who provide data processing services to us (for example, to support the delivery of, provide functionality on, or help to enhance the security of our Website), or who otherwise process personal data for purposes that are described in this Privacy Notice or notified to you when we collect your personal data.

  • to an actual or potential buyer (and its agents and advisers) in connection with any actual or proposed purchase, merger or acquisition of any part of our business, provided that we inform the buyer it must use your personal data only for the purposes disclosed in this Privacy Notice;

Third parties we share with for a commercial purpose (including sale/online advertising in the past 12 months):

Legal basis for processing personal data

Our legal basis for collecting and using the personal data described above will depend on the personal data concerned and the specific context in which we collect it.

However, we will normally collect personal data from you only (i) where we need the personal data to perform a contract with you, (ii) where the processing is in our legitimate interests and not overridden by your rights, or (iii) where we have your consent to do so. In some cases, we may also have a legal obligation to collect personal data from you or may otherwise need the personal data to protect your vital interests or those of another person.

If we ask you to provide personal data to comply with a legal requirement or to perform a contract with you, we will make this clear at the relevant time and advise you whether the provision of your personal data is mandatory or not (as well as of the possible consequences if you do not provide your personal data).

If we collect and use your personal data in reliance on our legitimate interests (or those of any third party), this will normally be to operate our platform and to communicate with you as necessary – for example, when responding to your queries, analyzing use of and improving our platform, undertaking marketing activities for existing customers as legally permitted, and detecting or preventing illegal activities. We may have other legitimate interests and we will make clear to you at the relevant time what those legitimate interests are. We rely on these legal bases to process data for the following purposes: to help provide the services (e.g. customer support and usage data) and to market our services to you (e.g. online advertising and gauging buyer intent).

If you have questions about or need further information concerning the legal basis on which we collect and use your personal data, please contact us using the contact details provided under the “How to contact us” heading at the bottom of this notice.

Cookies and similar tracking technology

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Website owners can use cookies for a variety of reasons that can include enabling their websites to work (or work more efficiently), providing personalized content and advertising, and creating website analytics.

Cookies set by the website owner (in this case, Stacksync) are called "first-party cookies". Only the website owner can access the first-party cookies it sets. Cookies set by parties other than the website owner are called "third-party cookies.” Third-party cookies enable third party features or functionality to be provided on or through the website (e.g. like advertising, interactive content and social sharing). The parties that set these third-party cookies can recognize your device both when it visits the website in question and also when it visits other websites that have partnered with them.

Stacksync may use web beacons, tags, flash cookies, HTML5, and scripts (“Data Tools”) in the Websites or in emails to help deliver cookies, count visits, understand usage and campaign effectiveness and determine whether an email has been opened and acted upon. Stacksync may receive reports based on the use of these technologies by our service/analytics providers on an individual and aggregated basis.

If you want to learn more about cookies, or how to control, disable or delete them, please visit for detailed guidance. For further information on how to manage Flash cookies, please click here.

Why do we use cookies?

We use first-party and third-party cookies for several reasons. Some cookies are required for technical reasons that are strictly necessary for our Websites to operate, and we refer to these as "essential" cookies. Other cookies also enable us to provide website functionality, or to enhance visitors' experience on our Websites by providing them with personalized content and advertising. This is described in more detail below.

Cookies collect certain standard information that your browser sends to the Websites such as your browser type and language, access times, and the address of the website from which you arrived at a Website. They may also collect information about your Internet Protocol (IP) address, clickstream behavior (i.e. the pages you view, the links you click, and other actions you take when you use the Websites) and product information. These are called first-party cookies and they are essential to the Websites’ operation.

Stacksync may also contract with third-party advertising networks that collect non-personally identifiable information and personal data through the Websites and emails and on third-party web sites. Ad networks follow your online activities over time by collecting usage data through Data Tools. They use this information to provide advertisements about products and services tailored to your interests. You may see these advertisements on other websites. This process also helps us manage and track the effectiveness of Stacksync’s marketing efforts.

The Websites may include third-party social media features, such as the Facebook Like button, and third-party widgets, such as the ‘Share This’ button or interactive mini-programs that run on the Websites. These features may collect your IP address, which page you are visiting on the Websites, and set a cookie to enable the feature to function properly. Your interaction with these features is governed by the privacy policy of the third-party company providing it.

We use third-party advertising companies to display ads on the Websites tailored to your individual interests based on your internet activity, as well as to provide advertising-related services such as ad delivery, reporting, attribution, analytics, and market research. You can manage your preferences with regards to the receipt of tailored advertisements in the cookie settings described below. Please note if these cookies are switched off, you will continue to see advertisements, but they will no longer be tailored to your interests.

The specific types of first- and third-party cookies served through our Websites and the purposes they perform are described in our cookie settings page.

What about other tracking technologies, like web beacons?

Cookies are not the only way to recognize or track visitors to a website. We may use other, similar technologies from time to time, like web beacons (sometimes called "tracking pixels" or "clear gifs"). These are tiny graphics files that contain a unique identifier that enable us to recognize when someone has visited our Website or opened an email that we have sent them. This allows us, for example, to monitor the traffic patterns of users from one page within our Websites to another, to deliver or communicate with cookies, to understand whether you have come to our Websites from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of email marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will often impair their functioning.

How can you control cookies?

You have the right to decide whether to accept or reject cookies. You can exercise your cookie preferences in our cookie settings page.

You can also set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our Websites though your access to some functionality and areas of our Websites may be restricted. As the means by which you can refuse cookies through your web browser controls vary from browser to browser, you should visit your browser's help menu for more information.

In addition, most advertising networks offer you a way to opt out of targeted advertising. If you would like to find out more information, please visit or if located in the European Union.

Stacksync‘s accountability for personal data that it receives under the Privacy Shield and subsequently transfers to a third party is described in the Privacy Shield Principles.
