Measurements
The measurements you type are sent to our drafting server only to calculate the pattern and are not stored with anything that identifies you. Your browser keeps the last measurements, units and paper choice in local storage so the form is filled in next time; you can remove them by clearing site data in your browser.
Downloads
PDF and SVG files are built in your browser. They are not uploaded anywhere.
Server logs
Like any website, our server and our CDN (Cloudflare) process IP addresses and request details to deliver pages and protect against abuse. The drafting server limits the number of requests per IP address and keeps such counters only for minutes.
Analytics and advertising
We may use Google Analytics to understand which patterns are used and Google AdSense to show ads that keep the site free. If we do, this page will list them, and visitors in the EU and UK will be asked for consent before any non-essential cookies are set.
