Prelude — Privacy Policy

Last updated: February 15, 2026

Overview

Prelude is a Chrome browser extension that detects competitor mentions on web pages and provides competitive intelligence to sales professionals.

Competitor identifiers: When a competitor keyword is detected, only the competitor name/ID is sent to our API (e.g. "vmware_broadcom").
Telemetry events (optional): Anonymous usage counts — detection count, view count, copy count. No content data included.
API key: Stored locally in chrome.storage.sync for authentication.

Permission	Reason
activeTab	Read visible page text to detect competitor mentions
storage	Cache battlecard data locally and store API key
sidePanel	Display the micro-battlecard sidebar
Host permissions	Detect competitors on email and CRM platforms

Prelude API (api.prelude.app): Our own backend. No user content is shared. We do NOT use Google Analytics or any third-party tracking.

Remove the extension from Chrome to delete all locally stored data.
