Overview

FASTCUP Control is a Chrome extension that operates entirely within your browser and works only on fastcup.net pages. The extension does not send your data to developer-owned servers and does not sell personal data.

Data Storage

The extension stores the following data locally in your browser using chrome.storage.sync:

• Rank remapping configuration (custom rank labels)
• Personal player overrides (player IDs/usernames and assigned ranks)
• Ban violation category labels
• UI preferences (language, rating replacement toggle)

This data is synced across your Chrome devices via your Google account through Chrome's built-in sync mechanism. We have no access to this data.

Data Processed on fastcup.net

To provide rank remapping and violation labels, the extension processes specific page data on fastcup.net and its subdomains:

• Website content required for UI rendering (player cards, rank badges, links, and match page elements)
• Match chat message content used only to detect configured violation labels (including custom labels set by the user)

This processing happens in-browser for the extension's single purpose.

Network Requests

The extension may read Fastcup GraphQL responses and may request Fastcup match/chat data from Fastcup infrastructure endpoints (for example hasura.fastcup.net) to render extension features on match pages. These requests are made only for fastcup.net functionality.

No Sale or Third-Party Transfer

FASTCUP Control does not:

• Sell user data
