Compliance Considerations
Collects push notification tokens, device identifiers, and engagement data. Push notification subscription requires explicit user opt-in via the browser/OS prompt. The OneSignal SDK itself may collect analytics data about notification delivery and engagement. Ensure marketing consent covers both the push subscription and associated analytics.
