Your measurements.
On your device.

This site does not create user accounts or send calculator measurements to an application server. There are no third-party fonts, advertising scripts or analytics scripts in this version.

What is saved

When you edit a calculator, its unit and input values, including any optional fabric price and currency label, are saved in browser local storage under drape-measure:drafts:v1. Only the latest draft for each calculator is kept. Your browser can remove this data when you clear site data or use private browsing.

Backups and restore

Back up downloads a JSON file containing the saved measurements for both calculators. Restore replaces both tools’ saved drafts after validating the file. Keep the backup somewhere you control. Clearing this site’s browser storage removes the saved drafts.

Other tabs and storage failures

If another tab changes the saved measurements, we show a notice. Tabs do not automatically merge edits. When storage is blocked, full or damaged, calculations remain available and we show that saving failed.

Network requests and future advertising

Pages and assets are delivered through Cloudflare. The hosting provider receives normal page and asset requests. This application does not include calculator measurements in those requests or submit measurement forms to the server.

Before advertising or analytics is connected, this notice and any necessary consent controls must be updated to describe the actual providers and behavior.
