When do I need a canonical tag?

When the same or very similar content is reachable at more than one URL (e.g. with and without a trailing slash, or a tracking parameter) - it tells search engines which URL is the one to index.

Does a canonical tag redirect visitors?

No - it is only a hint to search engines about indexing. Visitors still see whichever URL they requested; use a real redirect if you want visitors moved too.

Does this tool send my URL anywhere?

No - the tag is generated entirely in your browser.
