Privacy

What stays on your device

Interactive tools run in your browser. Practical Atlas currently has no accounts and does not ask you to submit personal profile data. Bookmarks, recently viewed pages and saved calculations use browser storage when those features are used. Clear them from the Saved desk or your browser’s site-data settings. Cached pages may remain available offline. The electricity worksheet and AI Markdown builders do not store form input; an explicit download creates a file on your device.

Measurement and advertising

No advertising or analytics provider is active on this build. When hosted, the hosting service necessarily receives network requests; its logging and retention settings must be documented by the publisher before public launch. Before either is enabled, this page will name the provider, purpose, retention period, and available controls.

Contact and external links

The publisher’s privacy inbox is not yet configured for this prelaunch build. Following an external source link takes you to that service, where its own policies apply.

Affiliate links

There are currently no affiliate links on this site. If that changes, affected links will be clearly marked and recommendations will remain editorially independent.
