Claude RTL Support — Chrome Extension | Last updated: June 2025
This extension does not collect, transmit, or share any user data.
What the extension does
Claude RTL Support adds right-to-left (RTL) text direction support to claude.ai. It auto-detects Arabic, Farsi, and other RTL languages and applies the correct text direction. Users can optionally choose a Persian/Arabic display font.
Data storage
The only data stored is your selected font preference (e.g. "Vazirmatn"), saved locally in your browser using the standard chrome.storage.sync API. This preference:
Is stored in your own browser / Google account sync
Is never sent to any server operated by this extension
Is never shared with any third party
Can be cleared at any time by removing the extension
Data we do NOT collect
Personally identifiable information (name, email, address)
Browsing history or web activity
The content of your conversations on claude.ai
Clicks, keystrokes, or any behavioral data
Location or device information
Third-party services
When you select a font, the extension loads that font's stylesheet from Google Fonts (fonts.googleapis.com). This is a standard browser request — Google's own privacy policy applies to that request. The extension itself does not pass any data to Google.
Permissions
storage — saves your font preference locally in the browser
