GravelSum calculates in your browser. The first release does not create user accounts, submit calculator values to a server, or store project values in cookies or local browser storage.

Hosting logs

The hosting and security provider may process standard request data such as IP address, requested URL, browser information, timestamps, and security events to deliver and protect the site. Retention and access depend on the host configuration.

Analytics and advertising

The first release does not enable advertising scripts or a simulated consent system. If analytics or advertising is introduced later, this notice and the consent experience will be updated before those tools are activated where required.

External links

Guide pages link to outside sources. Their operators set their own privacy practices.
