ways to understand how information about them is collected and used – both to provide our services and for
third party advertising purposes. We’ve tried to write this policy in a way that is easy for consumers to
understand at a “high level,” while still providing detail to allow sophisticated users (and privacy
advocates) to understand what data models we’re engaged in, and more generally, how interest-based advertising
We’ve also provided a section about the choices that you have with respect to “interest based advertising,”,
and we encourage you to read that section and exercise your “opt out” rights if you’re inclined to do that.
(But because interest based advertising leads to more relevant (and thus, less annoying) advertising, we hope
you won’t do that.)
Introduction and Background
OneSignal’s provides SDKs to mobile app developers and websites, and data and analytics services to other
data partners and advertisers. These web and mobile SDKs permit app developers and websites to send, manage,
optimize and customize push notifications to their users. All of these services (further described in this
website operators, partners and advertisers are referred to collectively as our “Clients.”
disclose information about the end users (“End Users”) of third-party mobile applications and
websites that use our Services. We also collect information on our corporate website(s), including any website
information (“OneSignal Website Information”) in Section 4, below.
We encourage consumers to learn about how information (including information we collect) can be used to
market to them, and how to exercise their choices to permit or, if they prefer, to limit such marketing. We
describe some ways consumers can exercise that choice or opt out of marketing in Section 6,
below, titled Consumer Control & Opt Out Options.
- Our SDKs: Information We Collect and Services We Provide
We refer to the information we collect from our SDKs as the ‘SDK Information.” The SDK
Information includes (or may include) the following:
Information Collected About End Users by Our Web SDKs
- Web pages visited that have implemented the SDK , and information about those visits (e.g., session
duration, time-stamp, referring URLs)
- What push notifications an End User has been sent
- Information about End User’s transactions and interactions with apps and websites
- IP address, from which geographic location may be inferred, as well as system configuration
- Email address which we may (in our discretion) hash or otherwise deidentify
- Information about an End User’s browser, such as, browser language type and version of operating
system (e.g., Android, iOS); network provider; language setting; time zone
- A unique cookie identifier, which may uniquely identify an End User (such as in de-identified or
anonymous form). These cookies may be associated with other Information, including with Data Segments,
which we describe in Section 3.
Information Collected About End Users by Our Mobile SDKs
- Apps an End User has installed and enabled, and how it has used an App (e.g., session duration,
- Purchases made within an app.
- Information about End User’s transactions and interactions with apps and websites
- Mobile advertising identifiers, such as iOS IDFAs and Android Advertising IDs (“Mobile IDs”). These
Mobile IDs may be associated with other Information, including with Data Segments.
- Precise Location information, generally an End User’s lat/long data (i.e., GPS-level data) or WiFi
information, which we may associate with Mobile IDs, and which may be collected whether or not an app is
- Email address, which we may (in our discretion) hash or otherwise deidentify.
- IP address as well as system configuration information
- Information associated with or related to devices, such as device type (e.g., mobile, tablet); type
and version of operating system (e.g., Android, iOS); network provider; mobile browser (e.g. Safari,
Chrome, etc.); language setting; time zone; and network status type (such as WiFi).
As noted above, we refer to all of the above collectively as the “SDK Information.”
- How We Use the SDK Information
We use the SDK Information to provide a variety of Services to our Clients. This includes:
- To Provide Our App and Website Services. We use the SDK Information to offer and support app and
website features provided through the SDKs, including those related to push notifications. This
includes, for instance, providing customer, technical and operational support for these features,
detecting and protecting against errors, fraud, or other criminal activity; resolving disputes and
enforcing our EULA and other rights we may have. It also includes analyzing, customizing, and improving
the features we offer Clients.
- To provide information and analytics to our Clients about the use of these app and website features
provided through the SDKs, or to help app developers and website operators create or enhance user
- To create inferences about End Users categorized into “Data Segments” or to help Clients do so. For
instance, if SDK Information indicates that a particular device is frequently seen at restaurants, we
might categorize a user for targeting of local restaurant offers. Or, if a user is frequently seen at
sports stadiums, we might categorize the user as a “Sports Fan.”
- To develop and use “predictive models” – data models that try to predict End Users’ potential future
behavior and interests on a per-device basis or across devices
- To analyze ad performance, for instance, by attributing End Users’ app installations, web visits, or
store visits to ad campaigns.
- Sometimes, the SDK Information may be used (by us or ad and data platforms we work with) to resolve
identities across multiple devices, such as to match IP addresses or hashed emails to link an End User
across (for instance) browsers, mobile devices, tablets, set top boxes, or other devices.
- Sometimes the SDK Information may be combined (by us or ad and data platforms we work with), to
perform any of the above functions, or other advertising, marketing or analytics services. Or, we may
aggregate and create data “models” to do this – creating algorithms in order to predict certain trends
and things that different End Users might have in common, for instance.
- We may provide End Users’ email addresses (which we generally “hash” or render non-human readable) to
online data platforms that “match” this information to online cookies or Mobile IDs in their system, and
tie the information (or associated IDs) to further interest-based or demographic data about End Users.
This may be done, for instance, to target advertising or provide analytics to brands and other
We, or ad and data platforms we work with, may deploy online cookies to track users across websites, or
to associate users (and these cookies) with Mobile IDs. We or they may do this to resolve user identifies
across platforms, and to better or more accurately target relevant ads to users (such as to a brand’s
customers). You can learn more about cookies and similar technologies, such as web beacons and SDKs, in
the Section titled “Cookies, Pixel Tags and SDKs.” We may also “append” or combine
certain SDK Information (such as hashed email addresses) to other information provided by third party data
providers, to learn more about End Users or to provide advertising and analytics services.
- How and Why We Share the SDK Information.
To Provide Services to Websites and Apps Using the SDKs
- We share the SDK Information with service providers, contractors and other companies to fulfill your
orders, operate our business, communicate with you and make available our Services and this Website.
These service providers may help us perform any of the activities set forth in
Section 2. For instance, we may share certain of the information we collect or receive
with companies that help us with billing and payment, marketing, advertising and email marketing,
- data enhancement (e.g., to provide more relevant offers), website hosting, technology and customer
support, web and marketing analytics, anti-fraud or security operations, and other operational,
marketing or business support.
- We likewise may share the SDK Information or Data Segments we create with website operators and app
developers (for instance, related to push notifications they send) for their advertising, analytics, or
To Provide Services to Marketers, Advertisers and Platforms They Work With
We also share SDK Information to provide or help us to provide advertising and marketing services as we
have described in Section 3, including as follows:
- With advertisers and their marketing providers, so they may provide targeted content and advertising
to you on websites and mobile applications With other third parties that target advertising. For those
familiar with the online ad ecosystem, these may include demand-side and supply-side advertising
platforms, data management platforms, advertising agency trading desks, proximity solution providers,
and other advertising technology providers, so they may provide targeted content and advertising to End
Users and others on third-party websites, mobile applications, and other advertising mediums (email,
direct mail, display media), and so that they may measure the effectiveness of this marketing.
- Similarly, we may work with service providers who, to enhance consumer privacy, use a non-human
readable “hashed” version of Information such as an email address when sending advertising offers by
email or display advertising (which may be linked to a cookie as described above).
- Sometimes we provide information (such as IP address, but excluding precise lat/long coordinates) to
third party platforms to help advertisers identify common users across different devices or browsers –
for instance, to identify a
The processes we’ve described above often involves cookies or similar technologies, which may be
associated with other information about you, e.g., your interests, demographics or transactions. This is
known generally as “Interest-Based Advertising.” We encourage users who are interested in controlling or
learning about this type of “interest-based advertising” to go to Section 6, titled
“Consumer Control & Opt-Out Options, or go to this this page operated by the online ad
industry trade association.
We may also share the SDK Information with third parties:
- If an End User or Client requests or authorizes
- If the information is provided to: (1) comply in good faith with applicable laws, rules, regulations,
or other agreements; or (3) protect our rights, property, or safety or the rights, property, or safety
of our users or any other person or entity
- If the disclosure is done as part of, including as part of due diligence for, a purchase, transfer,
or sale of services or assets (e.g., in the event that substantially all of our assets are acquired by
another party, any information we have may be one of the transferred assets) or in the event of
Even when you no longer access the SDKs, we may continue to use and share your Information as described

- Cookies, Pixel Tags and SDKs
Cookies and Pixel Tags. Cookies are small data files containing a string of
characters, such as an anonymous unique browser identifier. Cookies are stored on your computer or other
device and act as unique tags that identify your device or browser. Our servers may send your device a
cookie when you visit the OneSignal Websites, and our Clients and Partners may do likewise on our
Websites, our Clients’ websites, and elsewhere. A pixel tag (also commonly known as a web beacon or
clear GIF) is an invisible 1 x 1 pixel that is placed on certain web pages. When you access web pages on
which a pixel tag is deployed, the pixel tag may generate a generic notice of the visit and permit
OneSignal, our Clients or Partners to set or read cookies. Pixel tags are used in combination with
cookies to anonymously track the activity on a website by a particular browser on a particular device.
If you disable cookies, pixel tags simply detect an anonymous website visit. OneSignal, alone or with
the OneSignal Websites or the websites of our Clients or Partners), track trends, and collect
information about how you use our Clients’ or Partners’ websites or interact with advertising. We and
ads that better match your interests. We may sometimes use other locally stored objects in ways similar
because this may not always occur (depending on the browser you use), we recommend that if you wish to
opt out of notification features or third party interestbased advertising you instead follow the steps
we have set forth in Section 6 titled “Consumer Control & Opt-Out Options.”
Mobile Device Identifiers and SDKs. We may use or work with partners who use
mobile SDKs (including our own SDKs, which are described in more detail in this Policy) to collect
information, such as mobile identifiers (e.g., IDFAs and Android Advertising IDs), and information
related to how mobile devices and their users interact with our Services and those using our Services.
The SDK is computer code that app developers can include in their apps to enable ads to be shown, data
to be collected, and related services to be implemented. We may use this technology, for instance, to
analyze or measure certain advertising through mobile applications and browsers based on information
associated with your mobile device. If you would like to opt-out from having ads tailored to you in this
way on your mobile device, please follow the instructions in the below Section titled “Consumer
Control and Opt-Out Options.”
As described in Section 4 our Clients or Partners may use the above technologies
(sometimes, in combination with each other or other data such as IP addresses or hashed or de-identified
data files) to coordinate identifiers across platforms, browsers or devices, to more efficiently analyze
or target advertising.
Consumer Control & Opt-Out Options.
In most cases, consumers have control over whether or not they would like to receive relevant
advertisements and marketing email from our Clients.
- Opting Out of OneSignal Push Notifications
You may in most cases opt out of receiving push notifications by going to your device “Settings” and
clicking on “Notifications,” and then changing those settings for some or all of the apps on your
device. (Different device configurations, or updates to devices, may affect or change how these
Your choice to opt out of “Notifications” from the OneSignal platform will not affect ads placed by
any other organization.
- Opting Out of Online Interest-Based Advertising You can opt out of many
of the platforms and service providers that facilitate online interest-based advertising by visiting the
Digital Advertising Alliance’s consumer education and opt-out page, at
http://www.aboutads.info/. This type of opt out is cookie based,
which means that if you replace or upgrade your browser, or delete your cookies, you will need to opt
out again. Opting out in this way will not prevent you from receiving ads – it will just make the ads
you see less customized to you.
- Opting Out of “Cross-App” Advertising on Mobile Devices
You can opt out of having your mobile advertising identifiers used for certain types of
interest-based (also called “cross-app”) mobile behavioral advertising, by accessing the “settings” on
your Apple or Android mobile device, as follows:
- Apple Devices: If you have an Apple device, you can opt out of most app-based tracking for
interest-based advertising by updating to iOS 6.0 or higher and setting Limit Ad Tracking to ‘ON.’
You can do this by clicking on Settings -> General -> About -> Advertising and toggling Limit Ad
Tracking to ‘ON.’
- Android Devices: If you have an Android device, you can opt out of most app-based tracking for
interest-based advertising by opening the Google Settings app on your device, selecting Ads, and
then selecting the option to opt-out of interest-based ads.
Please note that these platforms control how these settings work, so the above may change. Likewise,
if your device uses other platforms not described above, you should check the settings for those
- Additional Choices
Advertisers may also provide ways for you to opt out from or limit their collection of information
from and about you. Please refer to the privacy policies for retailers, applications and websites to
learn more about their privacy practices.
You may opt not to receive promotional emails from us by contacting us as indicated below or by
following the “unsubscribe” instructions in any promotional email you receive from us. Please note,
however, that we may still send you non-promotional emails about your relationship with us.
