What we collect
When you browse
Like most websites, our hosting provider logs technical data for each request (IP address, browser, page and time) to keep the site secure and running. On the blog we also use Google Analytics, Umami and Microsoft Clarity to understand which pages are read and how they are used, and Google AdSense to show ads. These services may set cookies and receive data such as your IP address, device and pages visited, under their own privacy policies.
When you use a free tool
The calculations happen on your device, inside the page. We only count, per tool and per day, how many times it was opened and used: no cookies, no IP address and no inputs are stored for this.
When you contact us
The contact form on kuan-ai.com asks for your name, your email and your message. We use them only to answer you and keep them while the conversation is useful.
What we don't do
We don't sell your personal data, we don't ask for an account, and we don't send newsletters you didn't ask for.
Your choices
You can block or delete cookies in your browser settings, use an ad blocker, or opt out of personalised ads in your Google ad settings. You can ask us to access or delete any message you sent us through the contact form.
Third-party links
Articles link to other websites and tools. Their privacy practices are their own; check them before sharing information.
