YOUR PROJECT, YOUR DEVICE

A simple approach
to privacy.

Your quilt measurements are calculated in your browser. They are not sent to a calculator server.

Saving your work

“Restore saved” loads your last device save, replacing the working measurements. Reset returns to the example without deleting that save. The current calculated project is kept in this tab’s session storage so you can move between tools. “Save on device” also stores that project in this browser’s local storage. Export creates a JSON file that you can keep or import on another device. We do not offer cloud synchronization.

You can remove the saved project below. Your current form stays open; clear it with Reset in a calculator. Clearing browser storage also removes saved projects. Private browsing or browser settings may prevent saving.

Website requests

The hosting provider processes ordinary page requests, which can include an IP address and browser information. The application does not include advertising scripts, third-party analytics, or tracking cookies in this version. This page will need to be updated if those services are added.

Contacting support

For questions about the calculators or to report a problem, email support@quiltmathkit.com. Messages are forwarded through Cloudflare Email Routing to our support inbox hosted by Gmail. Your email address and the information you send are used to respond to your request. Please include only the project details needed to explain the issue.

Project files

Import reads your chosen file locally. Only supported calculator settings are used. Avoid putting personal or sensitive information in a project name, especially when you share an exported file or printed plan.
