Skyhook Privacy Policy

Effective Date: 01/25/2017

Skyhook Holding, Inc. and its wholly-owned subsidiary Skyhook Wireless, Inc. (together, “Skyhook”) value the personal privacy of its users, partners and prospects and is committed to maintaining that privacy and trust. This Privacy Policy explains how Skyhook collects and uses information through our location and context-enabling technology (the “Services”), as well as how Skyhook uses, stores and discloses information that is collected through our Websites ( and and the My.Skyhook customer portal (

Skyhook is a member of the Network Advertising Initiative (NAI) and complies with the NAI Code of Conduct, including its requirements as to transparency, notice and user control.  In addition, as described in our Privacy Shield Notice, Skyhook complies with the EU-U.S. Privacy Shield Framework as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of personal information transferred from the European Union to the United States. 

This Privacy Policy applies only to Skyhook, and not to any applications or devices that may use our Services. Please refer to the privacy policies of each application or device to understand their privacy and data collection practices.

1. Overview of the Skyhook Services

Location Determination: Skyhook offers a software (SDK) and cloud-based (API) technology platform that may be used to calculate the approximate geographic location of a device. See The Skyhook geolocation technology determines the location of a device by interfacing with Global Navigation Satellite Systems (such as GPS), utilizing the IP address of the device, and by scanning for nearby Wi-Fi access points and cell towers visible to the device.  This information is then processed on the device or on Skyhook’s servers to calculate and return the approximate geolocation (i.e., latitude/longitude) of the device.

Geofencing: Skyhook also offers on-device software that may be used to determine a device’s proximity to nearby points of interest, or whether a device has entered or exited a pre-defined geographic perimeter. See For example, an application developer may use Skyhook software to understand when a user is in proximity of a coffee shop, in order to deliver a relevant coupon, advertisement or different user experience.

Location-Based Personas and Attribution: Skyhook also offers data services to application developers, publishers, and advertisers that segment the interests or demographics of device users into defined profiles based on anonymous geolocation data. See The Skyhook technology will infer demographic information (such as gender, age, etc.) based on a device user’s presumed home census block and will infer interests and behaviors (apparel shopper, coffee drinker, business traveler) based on the venues a user visits over time. For example, if geolocation data collected or received from a partner suggests that a device has visited multiple auto dealerships in the past month, the Skyhook technology may characterize the device user as an auto buying intender. This information may be used to help partners better understand their users, to target users with more relevant experiences or advertisements, and to measure the efficacy of advertising campaigns or offers.

2. Information Collection by the Skyhook Services

Location Information:  When Skyhook’s geolocation platform is requested to provide a location result (e.g., to calculate a latitude/longitude), we may collect radio signal information that is provided or generated, including for example, location results, GPS coordinates, the MAC address of wireless routers (an alphanumeric code that is unique to that hardware device), the Received Signal Strength Indicator (a measurement of the strength of the access point’s signal at the time it is received by the mobile device), the cell ID of nearby cell towers, the IP address of the requesting device, UUID’s and Received Signal Strength Indicator for Bluetooth and associated Bluetooth data. When available, the Skyhook technology may also collect information about the device manufacturer, model, OS, version, and SDK version. 

All geolocation data is collected anonymously in a form that does not personally identify or track a user. In some cases, a third party application may also allow users to elect to determine the device’s location to a greater degree of precision by entering a street address. The street address is not linked to a device or a user.

For Context-Enabled Devices:  In implementations of the Skyhook technology that include our geofencing and personification services, in addition to the geolocation information above, Skyhook may also collect other attributes and information about the device, including:

  • a unique identifier or device ID (IDFA for iOS, Android ID for Android devices or a hashed partner ID that may specified and passed to Skyhook;
  • the time that a device is detected at a given location;
  • information about the device, including the device manufacturer, model, platform or operating system, time zone, network status (connected to Wi-Fi, etc.), timestamp and other similar information;
  • additional sensor information such as barometric pressure, accelerometer measurements, gyroscope measurements, device orientation, magnetic field measurements, direction of travel, motion activity (e.g. walking), or other similar sensor measurements;
  • information about the version and use of the Skyhook technology.

Information from Partners: From time to time, Skyhook may also receive information from our partners, which are usually mobile advertising networks and application developers/publishers. These partners may deliver advertising onto your mobile device and, through them, we may receive geolocation information (latitude/longitude) obtained from advertising impressions, including a unique identifier or device ID (IDFA for iOS, the Android ID for Android devices or a hashed partner ID), a time stamp, and in some cases, an IP address.

3. How Skyhook Uses Information

In general, Skyhook uses the information collected in order to operate, maintain and deliver our Services. In particular, with respect to de-identified geolocation signal information (such as Wi-Fi access point data and cell tower data that is not associated with any particular device ID), we may use such information:

  • To provide location-enabling service(s) by calculating and providing geographic location to application developers, device makers and operating systems, when users are opted in;
  • To improve the quality, accuracy and precision of Skyhook’s location database by adding the estimated location of new access points or cell towers or refining the estimated positions of existing access points or cell towers;
  • To aggregate geolocation data in an anonymous, de-identified manner in order to provide Skyhook and our partners with insights into the number and frequency of location requests in a particular area during a particular time interval; and
  • To approximate the geographic location where IP addresses are used for use in developing and marketing an IP geolocation services to partners, including publishers, data exchanges and advertising companies;

When geolocation information (i.e., a latitude/longitude) is associated with a particular unique identifier or Device ID and time information, Skyhook may also use the collected information:

  • To infer that a user is nearby, approaching or inside a particular venue or point of interest, which may be used by our partners to provide more relevant content, advertising and user experiences, as well as for analytics, attribution and reporting purposes;
  • To build anonymous location-based audience segments that infer demographic attributes and behavioral interests and activities in order to enable our partners to provide more relevant content and advertising, and for analytics and reporting purposes.

4. Opt Out Choices

Skyhook requires all clients and third parties using the Skyhook location and context services to provide notice regarding data collection and use, and to obtain all consents or permissions required, including without limitation any data such party collects, uses, and/or discloses from its users, the provision of such data to Skyhook, and the other party’s use of such data.

Skyhook also provides users to directly opt-out from Skyhook’s services as follows:

Location Information: For users who do not want any location data to be collected, the application, device, or operating system provides controls for disabling all location services.  This choice may limit the functionality of the device or installed applications

Device ID: If you wish to opt out of the Skyhook’s use of your Device ID to assist our partners with identifying your demographic information and interest segments for purposes of providing you with targeted ads, you may opt-out by clicking here. If you choose to opt out your Device ID(s), Skyhook will delete any collected data about this Device ID from Skyhook database, and quarantine the device ID so that Skyhook does not collect any data about this Device ID in the future or return or share any information about the Device ID to API or SDK requests.  

Skyhook also respects platform-level controls and restrictions, so that if you disable targeted advertising through controls offered by the application and/or through the iOS or Android “Limit Ad Tracking” or “Opt out of interest-based advertising” settings, we will abide fully by those setting. More information on how to access these settings is provided on the Skyhook opt out page, which can be accessed by clicking here. If a user chooses the “Limit Ad Tracking” or “Opt out of interest-based advertising” settings on iOS or Android, Skyhook will quarantine the device ID so that Skyhook does not collect any data about this device ID and will not return or share any information about the Device ID in response to API or SDK requests, instead returning an error code when the device ID has been opted out. Skyhook will also delete any encrypted device identified data from the opted-out user’s device.  

MAC Addresses: If you wish to opt out of Skyhook’s use of your MAC address to provide location, you may opt-out by clicking here. If you choose to opt out, Skyhook will (if applicable) delete the positioned record for that MAC address from the Skyhook database and will blacklist that MAC address so that we will not process or use that MAC address information in the future.

IP Addresses: If you wish to opt out of Skyhook’s use of your IP Address, you may opt-out by clicking here. If you choose to opt out, Skyhook will (if applicable) remove the positioned record for that IP address from the Skyhook database and will blacklist that IP address so that we will not process or use that IP address information in the future.

5. Data Retention and Data Security

Data on Device:  Skyhook may store an encrypted local cache of all Wi-Fi access points and cell towers in a surrounding area on the device to allow the device’s location to be determined without connecting to our servers.  A temporary encrypted history of scanned Wi-Fi access points and cell towers nearby may also be kept in memory on the user’s device and later transmitted to our servers. A maximum of 100 historic scans will be retained on device. This encrypted cache information will be deleted from the device the next time the Skyhook technology connects to the Skyhook servers, when the application terminates, or when the device is turned off.

Data Retention:  For all device identified data (i.e., location history that is associated with a unique Device ID), Skyhook will retain such data for up to twelve (12) months. After that time, some of the information we have (such as anonymous location logs) may be aggregated and anonymized for statistical purposes and stored indefinitely. Other anonymous location data that is not associated with any unique identifier, device ID or any other personally identifiable information may be stored indefinitely and used for purposes of improving and maintaining our location service.

Data Security: Skyhook is committed to protecting the security of information that is collected by its technology. We follow generally accepted industry standards to protect the information submitted to us, both during transmission and once we receive it. However, no method of transmission over the Internet, or method of electronic storage, is 100% secure. Therefore, we cannot guarantee the absolute security of all information.
