About ShareThis Sharing Tools

ShareThis provides a customizable social sharing tool, making sharing online content simple. You can easily share anything on the web with your friends on social sites, including Facebook, Twitter, Email, Digg, Reddit and more through one tool (“ShareThis Icon”). In addition to the sharing service offered directly to you, our technology also allows us to gather information regarding the browsing and sharing from those websites that use our ShareThis Icon or our advertising technology (“Publishers”), and enables ShareThis, Publishers, advertisers, and data partners to facilitate the delivery of relevant, targeted advertising, analytics, and data modeling based on social sharing (ShareThis Icon and all applications, services and other technology provided by ShareThis to Publishers, collectively “ShareThis Publisher Applications”).  You can recognize the websites which use the ShareThis Publisher Applications by the ShareThis Icon on the website.

Our aim is to enable advertisements by displaying products and/or services that you might be interested in, based on your recent browsing and/or sharing behavior, without identifying who you are by name, email or phone number. This is often called interest-based advertising (“IBA”) or online behavioral advertising (“OBA”). For example, if you visit and browse on Website A which uses ShareThis Publisher Applications, on a subsequent online visit to Website B, you may see ads personalized by your social sharing and/or browsing history on Website A but not personalized based on your name or other personally identifying information. For more information on IBA/OBA, click here.

Our Technology

We collect information via technical cookies placed on your browser, pixel tags, HTTP headers (or other communication protocols), and browser identifiers.  We do not use flash cookies or other locally stored objects (LSO) that may be used to circumvent user opt-out choices.

Additional Information

Online Web Environment: (desktop, tablet, and smartphone browsers)

ShareThis “tags” visitors on the websites that use ShareThis Publisher Applications with browser cookies. Users tagged by ShareThis are given a technical identifier, such as C62414AY9324FB5671069928026P0067.

The browser cookie tracks the content viewed by the visitor and pages of websites which use ShareThis Publisher Applications (“Our Publishers”). Pixel tags are used to transfer browsing data from visitors of Publishers’ websites to ShareThis and our data partners.

Cookies are small text files that contain a string of characters and uniquely identify a browser. They are sent to a computer by website operators or third parties. Most browsers are initially set up to accept cookies. You may, however, be able to change your browser settings to cause your browser to refuse third-party cookies or to indicate when a third-party cookie is being sent. Check your browser’s “Help” files to learn more about handling cookies on your browser.

Pixel tags are small strings of code that provide a method for delivering a graphic image on a webpage or other document. Pixel tags allow the operator of the webpage or other document, or a third party who serves the pixel tag, to set, read, and modify cookies on, and to transfer other data to, the browser used to view the webpage or other document. Pixel tags may also be used to obtain information about the computer being used to view that webpage or other document, including the IP address of the computer that the tag is sent to, the time it was sent, the user’s operating system and browser type, and other similar information (commonly known as the user agent string).

HTTP headers are transmitted whenever a webpage is viewed, and contain technical information required for communication between a client (your computer or device) and a server (the webpage you visit). Other electronic communication protocols (such as those used for email) also use headers to transmit information. This information may include information about the client browser, the requested webpage, server and other information the third party knows about you, your computer or device. Note: ShareThis does not use persistent identifiers like a carrier or device ID to revive a previously opt-out profile or deleted cookie.

Statistical IDs are created via an algorithm using pseudonymous information about your computer or device, including your operating system, user-agent string, IP address, Internet browser, installed fonts, and similar information.  This information makes your computer or device distinct enough for our systems to determine within a reasonable probability that they are encountering the same computer or device, including environments where ShareThis cookies are not supported. These statistical IDs are not 100% accurate. We may use statistical IDs for Publisher analytics and aggregate analytics. We collect this data to measure insights on the browsing and sharing activity from Publisher websites. Please keep in mind that your web browser may not permit you to block the use of these statistical IDs, and those browser settings that block cookies may have no effect on such techniques.

Other Environments: (Mobile applications)

In environments that do not support interest-based advertising cookies, like mobile applications, we do not collect Usage Data for interest-based advertising. See Data Collection and Use.

To serve ads in mobile applications, the advertiser identifiers, such as Google Advertising ID or Apple IDFA, depending on the operating system of your mobile device, may be used. These identifiers consist of a string of technical and random characters signaling out your device with a hash (non-reversible encrypting method). The advertiser identifier identifies your device but not you and can be reset by you. See your device manufacturer for more information.

Linking Environments: (browsers and mobile apps used)

To serve you personalized advertisements and provide a seamless online experience, third party data partners that we work with may link your identifiers on the different environments you are using. We may enable the linking of our Usage Data through cookie syncing. We do not use plain text personal information such as your name or address to operate the linking. Our data partners may use exact linking methods by leveraging the technical data collected through our technology such as advertising partner identifiers. Our data partners are members of the NAI or DAA and you can opt out of our tracking and theirs through NAI or DAA opt out mechanisms described in User Choices.

Data Collection and Use

We collect registration information and Usage Data (defined below). Your registration information is not connected to Usage Data.  For Usage Data, we use data that does not directly identify an individual (“Pseudonymised personal data”).  We collect and use technical data relating to a certain amount (not all!) of your browsing navigation to display personalized advertisements, provide analytics, and data modeling based on social sharing, by us or third parties.

Additional Information

How Data is Collected

Registration Information:

Many of our services can be used without registering with us.  However, you will need to register with us if you want to use some of our enhanced features.  If you chose to register with us, you affirm that you are 16 years of age or older and you will be providing us with certain information, some of which identifies you personally, such as your name and email, and other registration information. We do not sell or share registration information to third parties for marketing purposes. We may offer social media services in which our registered users can share information about themselves with their friends, including information about their interests and favorite websites.  You can decide what information you want to share with others in this manner.  This information will only be made available to friends with whom you specifically share such information.  However, whenever you voluntarily post personal information in public areas, like blogs, message boards, and forums, you should be aware that this information can be accessed by anyone with access to those places.  Please exercise discretion in deciding what information you disclose.

Note on Emails from Users with ShareThis Icon:

When you share to email with the ShareThis Icon, you chose how to connect to email from your device, depending on how email is set up on your device.  We do not verify your identity to that email account; we rely on your device email settings, using third-party authentication through Facebook, LinkedIn, Twitter, Google, Yahoo!, as applicable. Even still, we cannot block users from sending emails from your email address or to your email address. We are not responsible for the information provided or shared by users via the ShareThis Publisher Applications.

Usage Data:

We collect data when your device visits our website, uses or interacts with our services (including sharing content with the ShareThis Icon), when your device visits Publishers’ websites that use ShareThis Publisher Applications, and when your device views or clicks advertisements that we serve or are served on our behalf. Publishers are owners or operators of websites that make ShareThis Publisher Applications available on their site to collect Usage Data as a data controller in the European Union.  Publishers make the ShareThis Publisher Applications available on their site to facilitate their legitimate interest in enabling browsing and sharing content from their website and are required to deploy banner cookie notices/consent, as applicable by local law.

Usage Data may include, without limitation:

  • Unique IDs of a cookie placed on a web browser (example: 37d387ca-f68a-11e5-b87d-0e58954c72b1)
  • General click-stream behavior
    • Webpages viewed (including the URL addresses of such pages)
    • Search queries from which users are directed to a page
    • Navigation from page to page through the ShareThis services
    • Time spent on each page
    • Items clicked or selected
    • Content highlighted
  • IP addresses
  • Mobile advertising identifiers (Apple IDFA or Google AAID) which are specific technical data created by mobile manufacturers to allow personalization and customer analytics in a secure and non-identifying way for users (not collected by us but may be used with our data)
  • Information contained in HTTP headers or other intent transfer protocol signals
  • Attributes of computer or device usage, type of browser (e.g., Internet Explorer, Firefox, or Safari), and operating system (iOS or other for mobile devices)

The information listed above is pseudonymous (i.e., it does not directly identify an individual) and is not considered to be personal information in many jurisdictions in which we operate.  Specific types of the information listed above, such as Internet Protocol (IP) address, may be considered personal information in different parts of the world or when combined with other information.  Specific types of the information listed above that do not directly identify an individual may be considered personal information in different parts of the world or when combined with other information. In such cases, we treat this information as personal information.

Sensitive Data:

ShareThis is aware of the sensitivity of certain types of data. We do not create interest segments that reflect sensitive personal data, based on local jurisdictions.  While types of data considered sensitive may vary among users, we presently treat data as sensitive if it includes sensitive health information (such as a serious medical condition like cancer); certain aspects of a user’s personal life or financial situation (such as credit, insurance or employment eligibility); or use of, or interest in, gambling, alcoholic beverages, or “adult” products or services.  We do not create segments of EU consumers based on personal data considered to be sensitive in the EU (e.g., information about physical or mental health or condition, sexual orientation, race or ethnic origin, political opinions, religious or similar beliefs).  In most other jurisdictions, general health interest such as skin care, diet, or fitness are not sensitive and therefore ShareThis may use such interests.  Click here to view the list of health and wellness interest data segments available by ShareThis in such jurisdictions.


ShareThis does not intentionally collect data from, and does not tailor any segments to, children under 16 years of age.

Please note that publisher websites, advertisers and our other data partners may independently gain other demographical information about you after they place their own cookies or web beacons.  The use of cookies and pixel tags by these third-party advertisers, publishers, and ad networks are subject to their own privacy policies. For full disclosure on the cookies on your browser, you can use tools such as Ghostery Browser Extension which will display a list of cookies on each website you visit and the option to opt out for each.

How Data is Used

Registration Information:

We use your Registration Information: a) to fulfill requests for our services; b) to communicate with you and respond to your inquiries; c) to conduct research about the use of our services; d) to enable you to create an account, store log-in credentials, and customize your ShareThis services; e) to contact you from time to time about ShareThis services; and f) for ShareThis to provide offers for products and services of ShareThis and our partners that may be of interest to you.  If you decide to share your interests and your profile information with your friends on ShareThis, we will display your profile information according to the preferences you set in your account.  You can control the types of certain emails you receive by click on links in the emails, although you agree that we may always contact you to provide you with important information or notices required by ShareThis.

Usage Data:

ShareThis uses the usage data we collect and information collected from our third-party partners to create audience segments and to otherwise enable interest-based advertising (“Usage Data”).  Audience segments are groups of users and certain general interest categories that we have inferred based on a) demographic or interest data, b) a general geographic location derived from your IP address, c) the pages you view and links you click, and/or search terms you enter when using certain services.  These audience segments do not contain Personally Identifiable Information (“PII”); they are tied to a device, not a person.   For example, these segments may disclose that a user located in a geographic area may be interested in cars, but this information does not identify or include the name, email, phone number, mailing address, or user name of any specific individual.  Audience segments are not tied to Registration Information.

We may also use Usage Data for research and development purposes, for our internal operational purposes, and to create aggregate statistics for market research or analytics services.  These aggregated statistics do not include information that directly identifies an individual. We offer some of the Usage Data to Our customers for their own internal analytics or data modeling. In such cases, we contractually prohibit the customers from re-identifying you without your opt in consent.

Browser environment: (desktop, tablet, and smartphone browsers)

When you opt out as instructed in this section, an opt out cookie will be set on your browser. We must maintain the opt out cookie on your browser in order to recognize you as having opted out from our service. You must opt out again if you clear that cookie from your browser, use a different internet browser, or use a new computer to access the internet.

You can also opt out by visiting the following links. Please note these links allow you to opt out of interest-based advertising delivered by registered members (i.e., us and other companies that also provide interest-based advertising and are members of these self-regulatory organizations) on the current browser you are using when you opt out on their platform.

Network Advertising Initiative (“NAI”) Opt-Out Platform

Digital Advertising Alliance (“DAA”) Opt-Out Platform

European Interactive Digital Advertising Alliance (“EDAA”) Opt-Out Platform


The opt-out tools above are currently cookie-based, and prevent ShareThis from using Usage Data for interest-based advertising on the browser on which they are installed. As a result, the opt out will only function if your browser is set to accept third-party cookies, and may not function where cookies are sometimes automatically disabled or removed (potentially without your knowledge), like Safari. If you delete cookies, change your browser settings, switch browsers or computers, or use another operating system, you will need to opt out again.

Also, note:

Our statistical IDs are not used for interest-based advertising. Therefore, the industry opt out platforms listed above may not apply to our statistical IDs.  Also, please keep in mind that your web browser may not permit you to block the use of these statistical IDs, and those browser settings that block cookies may have no effect on such techniques.

Mobile environment:

While the opt-out methods described above often work for mobile web browsing, they are cookie-based and are therefore less reliable in mobile “app” environments that may not accept interest-based advertising cookies.

Instead, you can typically opt out at the mobile platform level by the limit ad tracking within the settings function, as described below. Though we do not collect data from mobile apps for interest-based advertising, we or third parties we work with may use such data collected by others in delivering interest-based ads.

Most Android Users:

To use the “opt-out of interest-based advertising” option, follow the instructions provided by Google here: Google Play Help.

Please note that this is a device setting and will disable interest-based ads from all providers, and not just for ShareThis.

Please note that this is a device setting and will disable interest-based ads from all providers, and not just for ShareThis.

Do Not Track and Cookie Blocking:

ShareThis does not process do-not-track signals from browsers. If you block third-party cookies from being set on your browser, you may not be able to enjoy some features or functionality of, and you may see the same content and advertisements repeatedly on, some websites. Blocking cookies will also block the function of our opt-out, which is an opt-out cookie.  Check your browser’s “Help” files to learn more about handling cookies on your browser.

The Ghostery browser extension is also a good tool to see a list of all third-party cookies on each website you visit and allows you to selectively opt out.
