Frequently asked questions
Are these tools free?
Yes. Every tool is free to use and none of them needs an account.
Do you store what I enter?
No. Most tools run entirely in your browser. The SERP preview, robots.txt and sitemap tools send your input to our server to compute the result, and nothing is kept once the response is sent.
