Is Tenhou English UI safe?

Clean risk

Tenhou English UI redirects non-default Tenhou tile image requests to mahjong.ie.

When a user selects a non-default tile set, the extension rewrites matching Tenhou CDN tile image loads to mahjong.ie. The redirected request includes the chosen tile set and tile image identifiers, and the rule is not added for the default tile set.
