Privacy Policy

Chatlyst is a browser extension built by an independent developer. We take your privacy seriously — which is why we designed the extension to work entirely on your machine, with no data leaving your browser.

Last updated: July 3, 2025

No data collection

Chatlyst does not collect, store, transmit, or share any personal information. We have no servers, no databases, and no analytics tracking. We do not know who you are, what you watch, or what links appear in your chat.

What the extension does

Chatlyst runs entirely inside your browser and does the following:

  • Reads links that appear in Twitch and Kick chat messages to detect supported platforms (YouTube, Spotify, Steam, TikTok, etc.).
  • Makes requests to third-party APIs (e.g. YouTube oEmbed, Spotify metadata) to fetch preview data for those links. These requests are made directly from your browser — no intermediary server is involved.
  • Stores your personal settings (enabled previews, spam threshold, blurred stats, etc.) in chrome.storage.local — local to your browser, never synced or sent anywhere.
  • Caches preview metadata temporarily in memory during your session to avoid redundant network requests. This cache is cleared when you close the tab.

Permissions explained

The extension requests the following Chrome permissions:

storage
Used to save your settings (which platforms to preview, spam detection threshold, revenue blur state) locally on your device. Nothing is synced to any external server.
host_permissions (twitch.tv, kick.com, all_urls)
Required to run the content script on Twitch and Kick pages, and to allow the background service worker to fetch preview metadata from third-party domains (YouTube, Spotify, Steam, etc.) on your behalf.

Third-party API requests

When a link is detected in chat, Chatlyst may make a network request to a third-party service to retrieve metadata (title, thumbnail, description). These services have their own privacy policies:

Chatlyst does not share any identifying information with these services — only the URL of the link being previewed is sent.

Revenue Blur feature

The Revenue Blur feature reads values from your Kick creator dashboard page and applies a CSS blur filter client-side. No financial data is read, stored, or transmitted by Chatlyst. Everything stays in your browser.

Children's privacy

Chatlyst does not knowingly collect data from anyone, including children under the age of 13. Since no data is collected at all, there is nothing to address under COPPA or similar regulations.

Changes to this policy

If this policy changes in a meaningful way (e.g. if data collection is introduced), we will update the date above and notify users through the Chrome Web Store update notes.
