RecipeTables converts the recipe on the page you explicitly ask it to convert, and nothing else.

What is sent to our server (recipetables.com): the URL of the page you clicked on, and — only when that site refuses our server's request — the already-rendered text of that page, so your own view can be converted instead. Nothing is sent for any page you have not clicked on. No list of pages you visit is built or stored.

What is stored on your device: a single number, a count of successful conversions. It is never transmitted.

The extension contains no analytics or tracking, contacts no third-party hosts, and executes no remote code. Results from pages whose publisher blocks automated readers are given a private, unlisted link and are never added to the public library.
