SafeGraph specializes in the collection of physical location data for data mining and analytics.




Products and Services

SafeGraph is a data company which aims to build a robust and detailed location-based tracking service for advertisers, industry, government and researchers. Products and services include:

  • SafeGraph Movement Panel: SafeGraph's "database of ultra-accurate GPS-location data that comes from anonymized mobile devices." The Movement panel offers:
    • Sink detection: Detection of inaccurate location data based on " specific coordinates occurring at impossibly high rates".
    • Teleporting detection: Detection of inaccurate location data when "devices appear to move at impossibly fast speeds, ostensibly traveling large distances between data points that occur next to each other" in data streams like bid streams.
    • Jumpiness detection: Detection of innacurate location data when "we see two consecutive points in time that are fairly close but still implausibly spaced" (eg, "the GPS receiver in your phone lags or if a nearby skyscraper interferes with the location signal") SafeGraph, 01
  • SafeGraph Places API: This "to easily find the places of interest that are near a given lat/long, ordered by distance or relevance" SafeGraph, 03.
  • OpenLocate: The OpenLocate SDK will "collect location data (like GPS) from phones" SafeGraph, 04. This includes an Android and iOS SDK. The service is built to provide developers complete control over their location data. Developers can build location-enabled features into their apps and "maintain complete control over how end-user data is collected, where it is stored, and which APIs it will be sent to". This includes sending to storage services (like Amazon S3) or APIs (such as Google Places API or SafeGraph's Places API) SafeGraph, 05.

Other services include:

  • "Detailed polygon maps on 50+ million U.S. places of interest
  • Understanding of each business's popularity, taxonomy, hours, etc.
  • Core investments in benchmarking via truth sets"
    • This includes Explicit Truth Sets (Check-ins, Daily diaries, Web surveys) and Implicit Truth Sets (Credit card data, Receipt data, First-party transactions)

Data from visits may include:

  • Core truth set for matching:
    • High-res GPS data
    • Deterministic data
    • Explicit and implicit truth
    • Data collected in background from large population
  • Deep places map:
    • Best polygons
    • Footprint geometries
    • Metadata
    • Categories
    • Hours of operation
  • Machine learning technology
    • Cross-validated against multiple independent 3rd party truth sets about where people go
  • Truth and accuracy
    • High Precision // Low false positive rate; High recall // Low false negative rate" SafeGraph, 06

Privacy Policy

Data collection (method and use): SafeGraph collects data from "trusted third-party data partners such as mobile application developers, through APIs and other delivery methods". The data collection and use is "governed by the privacy policy and legal terms of the data collector and the website using the data; it is not governed by SafeGraph." SafeGraph "aggregates data collected from our data partners, and allows third party customers to access the Data for a variety of purposes such as ad targeting, traffic analysis, and market research."

Information collected: Information collected includes "data regarding a device’s precise geographic location, as well as other mobile identifiers such as Apple IDFAs and Google Android IDs, and other information about users and their devices."

Jurisdictions: "SafeGraph stores and processes information on servers in many countries around the world. We therefore may process your information on a server located outside the country where you live... Our customers (or companies that help us process the Data) may be located in other countries, so the Data we provide may be processed or used in a variety of countries, other than those our users reside in." Customers of SafeGraph may create cross-device capabilities "to enable marketers to target users across various channels and devices."

Opt-out: SafeGraph informs users of opt-out procedures for interest-based advertising and location tracking. To opt out of interest-based advertising, they state, users can adjust settings in their Android or iOS devices. This procedure, which they note may change, is mentioned in the SafeGraph privacy policy "purely for informational purposes." SafeGraph further notes that "You also can remove your consent to having your location data collected by changing the settings on your device. (Certain services may lose functionality as a result.)" SafeGraph's Privacy Policy provides links to the Network Advertising Initiative and the Digital Advertising Alliance, as well as It informs users that these websites may provide additional opt-out options.

Retention: Information SafeGraph collects is "retained indefinitely unless there has been a direct opt-out with us as directed above."
