Frequently Asked Questions
Are leading and trailing spaces ignored?
No. Spaces remain part of each line, so a line with an extra space is distinct. Clean spacing first if you want those entries to match.
Does removing duplicate lines sort my list?
No. The first occurrence stays in place; subsequent matching lines are removed. Repeated empty lines are reduced to one.
Are the entries in my list uploaded?
No. Matching happens in memory in your browser, and Kalika does not save the list.
