What stays in your browser
Your saved keyword list, and the last inputs you typed into some tools (so they're still there after a refresh), are kept in your browser's local storage under keys starting with kf:. They never reach our server. Clear them any time:
What is sent when you use an AI feature
When you press an AI button (keyword ideas, long-tail, clustering, intent, titles, descriptions, briefs, YouTube ideas), the keyword or list you entered and any optional context are sent to our server and passed to a language model through Vercel AI Gateway. We don't store the request or the answer. To prevent abuse we keep a short-lived, in-memory count of requests per IP address, which is discarded within minutes. Don't paste personal or confidential information into the tools.
Everything else (pattern generation, cleaning, lexical clustering, rule-based intent, density, SERP preview, the mixer and the prioritiser) runs entirely in your browser.
Analytics
We use Ahrefs Web Analytics to count page views. It is cookieless and does not track you across sites.
Hosting
The site is hosted on Vercel, which processes standard server logs (such as IP address and user agent) to deliver and secure the service.
