Data Handling Guide

The OneSignal SDK collects data once it is initialized on your app or website. See Data Collected by the OneSignal SDK for more information.

The data collected is generally not PII (Personally Identifiable Information), with the exception of any sensitive user information you pass to us as Data Tags. Keep in mind that data that is linkable (such as first name or birthday) is still considered PII, even though it is non-sensitive. Clients dealing with PII need to have a Privacy Policy in place that states what they store.

This guide will go over how to use OneSignal without sending Personal User Data.

IP Address Collection

IP Addresses is typically not considered to be private, but in the EU and UK, it is considered personal data in some cases. For this reason, OneSignal will automatically not collect IP Addresses from all EU and UK Users.

If you wish to additionally prevent the storage of IP addresses from non-EU or UK users, you will need to contact [email protected] with each of your app's OneSignal App ID and first 5 digits of your REST API key for verification.

Personal Information Sent As Data Tags

OneSignal requires that you have appropriate consent for any data you send to us, including any personal data you may send to us as data tags or other fields.

For example, if you send us the user's email address or phone number, you must make sure you have all necessary consent to do so.

Some data is automatically collected by the OneSignal SDK. A complete list of automatically-collected information is available here: Data Collected by the OneSignal SDK.

Each of these fields can be customized by modifying our SDK code to exclude the field, or using provided helper methods. Instructions and examples on each of these methods is available below.

Getting User Consent

To assist with any compliance requirements, OneSignal has optional methods to delay initialization and prevent any data from being sent to OneSignal until the user has provided consent.

Your application can call these methods before the initialization of the OneSignal SDK to prevent data from being collected and anytime after the user provides consent to allow data collection. Until consent is provided, you can continue to call the SDK methods, but nothing will happen.

The consent setting is persisted between sessions. This means that your application only ever needs to collect consent by calling the provided method a single time, and the setting will be persisted (remembered) by the SDK.

A note for Wordpress clients

By default, the OneSignal WordPress plugin does not handle Personally Identifiable Information (PII) or EU and UK personal data.

Location Sharing

OneSignal provides a method to disable Location sharing within each mobile SDK.

Push Tokens

Push Tokens are generally not considered PII data because you can't share a push token with someone else and have it be used to reach that person or to determine anything about that person. We do however recommend disclosing to users in a privacy policy that data is shared with a 3rd party for the purposes of sending personalized or targeted notifications. But this would be true no matter what service you use.

Deleting User Data

See the Delete Users guide for more details on deleting user data.

Deleting Notification Data

Records of notifications that have been sent through OneSignal's dashboard can be deleted via the dashboard, but will otherwise be stored indefinitely unless you delete your OneSignal app.

Records of notifications sent through OneSignal's API will be deleted around 30 days of delivery.

Deleting Other Data

All other data is typically stored until your app is deleted. See Managing your OneSignal Account for more information.
