I don't want your data. I have enough problems. (￢_￢)

Privacy Policy:

I’m not watching you: This thing doesn't collect or sell anything. I don't even have a server to send it to.

Local only: Your settings and preferences stay on your machine. If you delete the addon, they're gone.

The API: It talks to the trusted api.frankfurter.app to get the rates. They get your IP because that's how the internet works, but they don't get you or your selected text.
