Privacy policy.
Last updated: 21 October 2026. This is a static website with no accounts, checkout, or newsletter. The short version: the free tools run entirely in your browser, contact goes through ordinary email, and analytics are aggregated without cookies.
The free tools send nothing
The website audit, cost planner, and break-even calculator run as JavaScript on your own device. Your answers and inputs are not transmitted to, stored on, or logged by this website. The “email report” and contact buttons open your own email application; nothing is sent unless you choose to send it.
Email contact
When you email swustfang@gmail.com, the information you include (such as your name, email address, website address, and message) is processed through ordinary email to answer your request or discuss a project. It is not sold, shared with advertisers, or used to add you to a mailing list. Retention follows normal email practice; ask at any time to have a thread deleted.
Cloudflare Web Analytics
This site uses Cloudflare Web Analytics to understand rough traffic levels and which pages are read. It is a cookieless, privacy-first product: it does not use advertising identifiers, does not build cross-site profiles, and reports aggregated metrics such as page views, referrer type, country-level location, and browser/device classes. Raw visitor data is not available to this site. See Cloudflare’s own documentation for the current details of its product.
The site is also served through Cloudflare’s network, which processes requests under its own privacy and data-processing terms in order to deliver and protect pages.
Cookies and local storage
This site sets no advertising or tracking cookies and does not use third-party ad pixels. The mobile menu and tools use standard in-page JavaScript only.
Concept previews
The pages under /concepts/ are fictional design demonstrations. Company names, phone numbers, addresses, reviews, ratings, and credentials shown there are sample content for layout purposes, not real businesses. The pages are marked noindex and excluded from the sitemap. Some sample photography originates from publicly visible business websites and is shown for design demonstration only; rights holders may request removal through the contact address above.
Your choices
You can block JavaScript or analytics in your browser; every informational page remains readable. For questions about data sent by email, or to request correction or deletion, contact swustfang@gmail.com.
