Analytics and cookies
We use Google Tag Manager to load Google Analytics 4. Google Analytics sets cookies (such as _ga) to count visits and show which pages are useful: pages viewed, how you arrived, approximate location (region, not precise), and device and browser type. We don’t use it to identify you, and we don’t run advertising trackers. Google processes this data under its privacy policy. You can block or delete these cookies in your browser settings, or use Google’s Analytics opt-out add-on.
Tools and local storage
Gear shortlists, packing-list choices and entered estimates, learning-path checks, and the practice and demo notebooks save data only in this browser (localStorage). We never see it. Reset each packing list in Gear lists, reset the learning path in My game, un-save products in the catalog, use “Clear notebook” on the tools page, and use “Clear demo records” in the demo notebook to remove each set. Demo import reads a selected JSON file locally, validates it and replaces only demo records; no file upload occurs. Clearing your browser data also deletes it. Avoid entering sensitive information.
Affiliate links and purchases
As an Amazon Associate I earn from qualifying purchases. Some product links are Amazon affiliate links. Amazon and other retailers have their own privacy policies and may set cookies when you visit them. Manufacturer and other retailer links that are not marked as Amazon links carry no tracking from us. We don’t see your card details. There is no paid checkout or Gumroad product on this site yet.
What we don’t collect
There is no account system, newsletter, or contact form on this site yet. We don’t sell personal information.
Hosting
The site is hosted on Cloudflare, which may process routine connection data (such as IP address and request logs) to deliver pages, under its privacy policy.
