Privacy by default.

The current Gravel Project Planner does not require an account, name, email address or street address.

Calculator inputs

The planner is designed to calculate in your browser. When browser storage is available, project inputs are saved locally on your device so they can persist between visits. You can clear that saved project by using Reset or by clearing site data in your browser.

Hosting data

Like most websites, the hosting provider may process standard technical request information needed to deliver the site, such as IP address, browser information and request timestamps, under its own infrastructure and policies.

Analytics and advertising

This release does not intentionally include third-party analytics or advertising scripts. If analytics, advertising or affiliate technology is added later, this page should be updated before those services are enabled.

Contact information

No contact form is enabled in the initial release. This privacy page will be updated with a contact method if one is added.
