On a new Claude chat at claude.ai or claude.com, the extension reads the on-screen model name. If it is Fable, it clicks Opus in Claude’s own model menu. If you pick Fable after that, it leaves your choice alone.
Nothing. The extension does not have an account, analytics, ads, or a server. It does not store your chats, prompts, files, cookies, or identity.
It only reads the model-picker label in the current tab, in memory, so it can decide whether to click Opus. That text is not saved and is not sent anywhere.
We do not share, sell, or transfer user data. There is none to share.
The extension asks to run only on https://claude.ai/* and
https://claude.com/*. That is so it can see the model chip
and click Opus. It does not run on other sites.
Use of information from the page is limited to the single purpose above: defaulting a new Claude chat off Fable onto Opus. It is not used for advertising, retargeting, credit, or sale to data brokers. No human reads your page content through this extension.
