WCL Overlay — Privacy Policy

Last updated: March 2026

What this extension does

WCL Overlay is a browser extension that injects an analysis panel onto WarcraftLogs.com report pages. It communicates exclusively with the WarcraftLogs API using credentials you provide.

Data collection

This extension does not collect, store, transmit, or share any personal data. No analytics, no tracking, no external servers.

Credentials storage

Your WarcraftLogs API Client ID and Client Secret are stored locally in your browser using chrome.storage.local. They are only ever sent to warcraftlogs.com to authenticate API requests. They are never sent anywhere else.

Local storage

The extension saves your panel position, size, and any interrupt or healer CD plans you create to chrome.storage.local. This data stays on your device and is never transmitted.

Third-party services

The only external service this extension communicates with is WarcraftLogs.com (api.warcraftlogs.com). No other third-party services are contacted.
