Sift Service Privacy Notice

Effective: April 15, 2019

Previous Service Privacy Notice available here link to Service Privacy Notice

Our commitment to privacy

Sift Science, Inc. (“Sift”, “we” or “us”) respects your privacy and wants you to be informed about what we do. Sift provides a suite of digital trust and safety products (the “Sift Services”) designed to help online businesses (our “Customers”) detect and prevent fraud and other malicious behavior on their digital properties, such as their websites and mobile applications (“Customer Sites”).

This Service Privacy Notice (this “Notice”) explains who we are and how we collect, share, and use personal information about you when: (i) you use the Sift Services as an authorized end user under our Customer’s (your employer’s) account (“Authorized User”); or (ii) you interact with any of the Customer Sites that use the Sift Services as a digital end user (“End User”). We also include information about how you can exercise your privacy rights. “You” may be an End User and/or Authorized User depending on the context.

Please note that this Notice does not describe our collection and use of personal information when visitors access our website. For information about how we collect and use information via our website ( and its subdomains), please see our Website Privacy Notice.

Who we are

Sift is a Software-as-a-Service (SaaS) company based in San Francisco, California. We help our Customers detect and address fraud and other malicious behavior on their Customer Sites using our proprietary real-time machine learning technology.

In doing so, we need to collect and process information about End Users who interact with Customer Sites. Our cloud-based machine learning platform uses this information to predict End Users intent and prevent fraudulent activity in real time.

We have three core product offerings for our Customers: Payment Protection (reduces fraudulent payments), Account Defense (reduces fake account creation and prevents bad actors from accessing trust-worthy accounts) and Content Integrity (protects Customer Sites from malicious content). You can find out more about these offerings here. find out more about Sift's core product offerings

How the Sift Services work

Customers provide us with data and information about End Users and their interactions with the applicable Customer Sites through our Application Programming Interfaces (APIs). In addition, we collect data directly from End Users through standard tracking technologies (like our JavaScript code or SDK), which our Customers can embed on their Customer Sites. We refer to all of this data as "Customer Data" - as described in Part II below.

We then apply our proprietary modeling and algorithms to the Customer Data to produce what we refer to as “Analytical Results”. These Analytical Results include a relative fraud score which is a numerical indicator of the likelihood of fraud for a particular event on the Customer Site (e.g., a purchase transaction, the posting of content, creation of a profile). For example, our machine learning may assign a low score for the placement of an order of clothing by an End User, which may mean for a particular Customer that this clothing order is unlikely to be associated with fraud. In addition to the score, the Analytical Results include supporting evidence for the score (e.g., top data inputs) and aggregated reporting and insights.

The Analytical Results are used by Customers to assist them in identifying and preventing fraudulent activity on their Customer Sites – our Customers use the results to decide what action to take or not to take. For example, a Customer may choose to block a transaction if they believe there is a high risk of it being a fraudulent transaction. Customers also provide us with ongoing feedback on the accuracy of the Analytical Results by reviewing the activity on their Customer Sites, which in turn improves our proprietary modeling and algorithms.



Information We Collect About End Users

Information provided by our Customers: Our Customers decide the type of Customer Data they wish to send to Sift for analysis within the Sift Services. Our solutions and support teams work closely with Customers to assess the utility of the specific Customer Data they send to us. For example, Sift guides Customers as to whether a particular data type (e.g., billing method) may be relevant in assessing the particular activity (e.g., likelihood of stolen payment credentials). While it will depend on the specific product offering and Customer relationship, the Customer Data that Customers typically send to us through our API integration include:

  • Contact details (such as, your email address, postal address, phone number, and user login);
  • Information about your device (such as, your IP address, session ID, mobile/desktop device properties, and metadata);
  • Transaction information (such as, information about items you've purchased on Customer Sites, currency codes, billing method, and partial credit card information); and
  • Customer Site communication information (such as, feedback, messaging, reviews or images you may have provided on or within Customer Sites).

Information we automatically collect when you visit Customer Sites: As further explained below, we use and deploy certain standard tracking technologies to automatically collect certain information about your device when you interact with and use Customer Sites. Some of this information (including, for example, your IP address and certain unique identifiers), may identify a particular computer or device and may be "personal data" in some jurisdictions, including the EU. Depending on whether you visit a Customer Site via an app or a webpage, the information we collect includes:

  • Browser and device information, such as the device type and model, manufacturer, operating system type and version (e.g. iOS or Android), web browser type and version (e.g., Chrome or Safari), user-agent, carrier name/code and country code, time zone, the network connection type, IP address, hardware-based identifiers (e.g. MAC address), host name, device identifiers (such as its iOS Identifier for Advertisers (IDFA), Android/Google Advertising ID (AAID or GAID), canvas fingerprint, and characteristics related to emulation or rooted (such as if your device is "jailbroken"), app name and version. We also collect character set, host name, language, page title and URL, referrer URL, number of fonts, fonts hash, number of plugins, plugins hash, screen height and width, color depth, platform, cookie footprint, maximum touch points, JavaEnabled, session storage, local storage, whether the resolution has been tampered, language or OS, whether ad blocking is enabled, whether do not track is enabled, flash socket IP and flash identifier. The SDK will also collect phone-related metadata (battery level, device properties, carrier name); and
  • Information about an End User’s behavior on Customer's Sites, such as information about the activities on those Customer Sites, session ID, session start/stop time, timezone offset, and geolocation (including latitude and longitude coordinates, but only if the Customer Site (like an app) has enabled location services on the device).

Information we collect from third party sources: We combine or enhance the information we collect about you with limited information from third parties (such as, location data providers or identity verification services). For example, we may work with a small number of providers that match publicly-available information from social media with End Users' email addresses provided to us, or provide us with a publicly-available address based on name or the longitude/latitudinal of an address.

How We Use End Users Information and the Legal Bases

Sift only uses the Customer Data for the limited purposes of providing, maintaining, and developing the Sift Services. Sift does not process Customer Data for any other purpose.

We base our processing of your personal information on: (i) our legitimate interests in operating the Sift Services and better detecting and preventing fraud and malicious behavior on Customer Sites; and (ii) our (and our Customers) legitimate interest in combating fraud and maintaining safe online experiences for our Customers and their End Users.

If you have questions about or need further information concerning the legal basis on which we collect and use your personal information, including any legitimate interests relied upon, please contact us as provided under the How to contact us section at the end of this Notice.

How We Use Tracking Technologies to Collect Information about End Users

We use standard tracking technologies to automatically collect certain information (as described in the Information We Collect About End Users section) from your device and/or browser when you interact with Customer Sites so that we can use the information collected for the limited purposes described above in this Notice.

We use the following tracking technologies:

  • JS Snippet: A JavaScript code (“JS Snippet”), also called a tag or pixel, is a tiny snippet of code inserted into the content of the Customer Site. You can disable JavaScript by changing the settings on your browser. Information about the procedure to follow can usually be found on your internet browser provider’s website via your help screen.
  • Mobile "SDKs" or "Software Development Kits": These are blocks of code that are embedded into a Customer app that allow Sift to collect certain information as further described above. You can disable the collection of your information by Sift through the SDK by accessing your mobile device settings and resetting your device ID by following the most recent published instructions. This means that the device ID (along with any information collected about that identifier) that was previously assigned to you will be disassociated. This means that if (for example) at a later stage, you visit a mobile app that is a Customer Site, we will not be able to use any of your past information, and you will for all practical purposes be a new End User to our system. You may also stop the collection of location information by particular apps by changing the preferences on your mobile device.
  • Canvas Fingerprinting: We use canvas fingerprinting, which is a tracking technique that allows us to render graphic images from built-in features of HTML5 Canvas in your browser. The canvas image is often rendered differently on different devices because of a number of factors (such as, your web browser version, operating system and its settings, and installed graphics hardware), and this will allow us to distinguish you from other End Users. If you would like to disable canvas fingerprinting, you may choose to disable JavaScript or download a browser extension that blocks canvas fingerprinting techniques; however doing so may impair the functionality of the Sift Services.

When an End User views a Customer Site or uses a Customer’s mobile app, Sift servers are notified, and we are able to collect information from the browser or application as described above.


Information We Collect About Authorized Users

Information you provide to us when you use the Sift Services: You (or your organization's administrator) may provide certain personal information to us through the Sift Services – for example, when you register for the Sift Services, when you consult with our customer support, send us an email or communicate with us in any way in connection with the Sift Services.
