ClearCast — Privacy Policy

Last Updated: March 24, 2026

Overview

ClearCast is a browser extension that fixes video rendering issues during screen sharing. This privacy policy explains how ClearCast handles user data.

Data Collection

ClearCast does not collect, store, transmit, or share any user data. Specifically:

• No browsing history is collected or transmitted.
• No personal information is collected or transmitted.
• No analytics or telemetry data is gathered.
• No cookies are set or read by the extension.
• No network requests are made by the extension. ClearCast operates entirely locally within the browser.
• No video content is accessed, recorded, captured, or transmitted.

Data Storage

ClearCast stores only two pieces of information locally on the user’s device using Chrome’s chrome.storage.local API:

1. Extension enabled/disabled state — a single boolean value.
2. User-added custom site list — domain names the user has manually added to the extension’s site list.

This data never leaves the user’s device and is deleted when the extension is uninstalled.

Permissions

ClearCast requests the following permissions:

• Host permissions for specific streaming sites — required to inject CSS that fixes video rendering during screen sharing. The extension ships with a predefined list of major streaming platforms.
• Optional host permissions — allows users to manually add additional sites. Chrome displays a permission prompt for each site added. Permissions can be revoked at any time from within the extension.
• Storage — used to persist the extension’s on/off state and user-added site list locally.
• Scripting — used to toggle the extension’s functionality on and off without requiring a page reload.

Third-Party Services

ClearCast does not integrate with, communicate with, or send data to any third-party services, servers, APIs, or analytics platforms.

Changes to This Policy

If this policy is updated, the changes will be posted here with an updated date.
