Questions
Which copy of a repeated line is kept?
The first one. Later repeats are removed, and the original order is kept unless you choose to sort.
What does Ignore upper/lower case do?
It treats "Apple" and "apple" as the same line, so only the first is kept.
Can it handle long lists?
Yes. Lists with hundreds of thousands of lines work in a modern browser.
Is my list private?
Yes. Everything happens in your browser.
