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 and uncalculated input drafts for each tool are kept in this tab’s session storage, so you can reload or return without losing your inputs. Drafts may contain incomplete values and do not count as calculated plans. The most recent reset, restore, import or save can be undone while the calculator page stays open. “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. We use Cloudflare’s automatic Workers invocation logs to troubleshoot requests. These logs may contain request headers, IP addresses, browser and location information, the requested URL, response status and processing times. Query-string redaction is enabled. 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.
