Privacy and browser storage
How site delivery, local projects, downloads and optional email contact handle information.
Calculations and projects
Room measurements, product fields and calculations run in your browser. The site has no project upload endpoint, account system or cloud database. Inputs are displayed as text. A draft is written to this site's localStorage only when you choose Save in this browser. It includes the project and save time.
Control the local copy
Choose Continue saved project to restore a draft; it is not silently loaded. Delete browser draft removes that saved copy, while the current page and downloaded files may still contain your information. Clearing browser site data can remove the draft. Other users of the same browser profile may be able to access it. Download JSON for a separate backup and store it appropriately.
Downloads, clipboard and printing
CSV and JSON files are created locally. Your browser controls the destination and download history. Copy is requested only after your click; if permission is denied, a selectable text dialog is offered. Printing and saving PDF use your browser and device. These copies are not deleted when you clear a website draft.
Hosting and contact
Cloudflare delivers the static website and may process request information such as IP address and user agent for hosting and security. Browser-local calculations do not mean the hosting provider sees no web requests. See Cloudflare's privacy policy.
Email contact is voluntary and uses email providers outside the calculator. Do not send private measurements unless you intend to share them.
Ads and analytics
No advertising, third-party analytics or remote fonts are loaded by this release. We do not set application cookies. LocalStorage is used for explicit drafts; it is not a cookie. If advertising or analytics is introduced, this policy and any required consent mechanism will be updated before those services are enabled.
