## Description

Cookie Brother is a local browser extension for managing cookies directly inside your browser profile.

It helps you inspect, import, export, and clean browser cookies without sending cookie data to any external server. All cookie processing happens locally through the browser extension APIs.

Key features:
- View cookies for the current site or all sites in the browser profile
- Search cookies by name, value, domain, path, and attributes
- Import cookies from JSON, Netscape cookies.txt, Set-Cookie headers, Cookie headers, HAR-like data, Playwright/Puppeteer storageState, and Chrome SQLite-style cookie fields
- Export cookies as Cookie Brother JSON, Netscape cookies.txt, or Cookie header text
- Delete individual cookies, current-site cookies, selected domains, or filtered cookie groups
- Protect important domains from accidental cleanup
- Show a local badge count for current-site cookies
- Use a localized interface with automatic browser-language detection

Cookie Brother is useful for developers, testers, QA engineers, automation workflows, and advanced users who need a simple local tool for cookie backup, migration, inspection, or cleanup.

Privacy:
Cookie Brother does not collect, sell, transfer, or remotely store cookie data. Imported files, exported files, cookie values, and settings stay on the user's device unless the user chooses to export or copy them.

Important:
Cookies can contain sensitive account access data. Only import cookie files from sources you trust and store exported cookie files securely.
