The SDK stores these events on the device while offline: * Identify calls, screen views, custom events, and Auto Capture events. * Flow views, dismissals, completions, and step views and completions. * Survey views, dismissals, completions, responses, and step views, skips, and submissions. * NPS views, dismissals, and feedback submissions. * Push-notification opens, excluding test notifications. Stored events survive app restarts and are sent together in a batch ordered by stored timestamps when the connection returns, before pending live events. Identify a user, or call `anonymous()`, before collecting events. Experience interactions and push opens are not persisted without a current user ID. Offline Mode is always enabled and requires no additional configuration. ### Limitations * All supported event types share local storage of up to **3 MB** or **5,000 events**, whichever limit is reached first. * When either limit is reached, new events are not stored until space becomes available. * Switching accounts or logging out clears stored events. *** [**For any questions or concerns, please reach out to support@userpilot.com**](mailto:support@userpilot.com)
