Effective 27 October 2026. This notice describes the current educational preview. A complete operator-specific privacy policy must be reviewed before a public launch.

Planning data

Calculations run in your browser. Using “Save on device” stores your project in this browser’s local storage. Temporary session storage keeps your current work when navigating between HTML pages in the same browser tab. JSON imports are read locally. Report exports are generated locally. This edition has no project upload or application account system.

Removing your saved project

You can remove the saved project below, or clear this site’s data in your browser. Removing a saved copy does not delete files you have downloaded.

Hosting and external services

Hosting providers may process technical request and access information to deliver and secure the site. Fonts are bundled with this site; no external font request is needed. Links to primary sources open external services with their own privacy practices. No advertising pixels or application analytics have been added.

Contact drafts

The contact form exports an inquiry file to your device. It does not transmit the entered message, name or email. Email links open your email application; any message you choose to send is handled by your email provider and the recipient. Do not put banking details or sensitive documents into the draft.
