What this site collects
The calculators run in your browser. The values you enter are not sent to a server by the site’s own code. If you choose to save a project, it is stored only in your browser’s local storage on this device and is never uploaded.
Hosting and server logs
This site is hosted on Vercel. Like any web host, Vercel receives standard request data (such as IP address, requested page, browser type and time) to serve pages and keep the service secure. Those logs are handled by the hosting provider under its own policy; the operator does not run additional logging or tracking.
Analytics and search data
No third-party analytics scripts are loaded, and none are connected at the time of this notice. Once the site is verified in Google Search Console, the operator will review aggregate Google Search data (queries, impressions, clicks by page and country). That report describes Google Search activity; it does not identify individual visitors to this site. This section will be updated on the day any analytics tool is connected, before it goes live.
Advertising
This site currently shows no advertising. If Google AdSense is added after the site is approved, this notice will be updated before any ads appear, including the choices available to you.
Contact email
If you email the operator, your message and address are used only to handle your request and are kept only as long as needed to resolve it.
