Privacy & Data Flow

Data Collection

Cookies and local storage used by this script

Cookies

ph_current_session30 minutes
Stores information about the current user session.
ph_previous_session1 hour
Stores information about the previous user session.
ph_persistent2 years
Stores a persistent anonymous ID for the user.
ph_session_id30 minutes

Local Storage

ph_opt_out
Stores user's opt-out preference for PostHog tracking. If set, PostHog will not send data for this user. This is typically set by a consent management system or user preference. This key ensures that the user's choice to opt out of tracking persists across sessions and page loads.
ph_posthog
Stores various PostHog-related client-side data, including feature flags, user properties, and session information. This data helps maintain context for the user within the PostHog ecosystem, such as which feature variations they are exposed to or their current session state.
ph_survey_*
Stores survey states, responses, or visibility information to manage survey display. This prevents showing the same survey repeatedly and can store partial responses if a user closes a survey before completing it. It ensures a consistent survey experience across page loads for a user.

AI Insights & Alternatives

Description

A comprehensive overview of this resource

This script is part of the PostHog platform, specifically designed to handle in-app surveys. It initializes the survey functionality on a website, allowing site owners to configure and display targeted surveys to their users. When loaded, it communicates with the PostHog backend to fetch survey configurations, determine eligibility for specific users based on defined criteria (e.g., user properties, events triggered), and then renders the survey interface within the web page. User responses are captured by this script and sent back to PostHog's analytics system for analysis. It manages the display logic, including when and how often surveys are shown, and ensures survey data is collected efficiently.
