Who operates this site

Practical Atlas is published by Eigenlabs. Our public contact channel is being configured. We do not yet offer a verified email channel on this build.

Information on your device

Calculators run in your browser. There are no public accounts. Saved references, recent pages, and saved calculation features use browser storage; clear these through the Saved desk or browser site-data settings. Offline pages remain until browser caches are cleared or updated. The household worksheet, replacement comparison, and AI Markdown builders do not upload your inputs. Explicit downloads create files on your device.

Google advertising

The site loads the Google AdSense library using publisher ID ca-pub-3800634936237031. Google and its advertising partners may use cookies and similar technologies to serve, personalize, and measure ads, depending on account settings, region, and consent. Loading this library makes a request to Google even when no advertisement is visible. The absence of manually inserted ad units does not prove that no ad or third-party request can occur.

Read how Google uses information from partner sites and Google's Privacy Policy. Manage personalized advertising preferences in My Ad Center. These controls do not remove every advertisement or replace a consent choice where one is required.

Consent and regional choices

Where a consent message is shown, use it to accept, decline, or manage applicable purposes. Consent requirements depend on region and ad configuration. We do not present a custom cookie button as a substitute for a Google-certified consent platform. Browser cookie controls can clear existing site data; they are not a guarantee that all later network requests stop.

Hosting and external services

Cloudflare delivers and protects this website and receives request information such as IP address, requested URL, and browser information. See Cloudflare's privacy policy. Provider retention periods and account settings differ; this site does not claim a fixed retention period it cannot verify. External source links follow the destination's own privacy practices. There is no separate Google Analytics tag in this build.

Editorial independence

There are no affiliate links in the current content. Any future commercial relationship must be disclosed where relevant. Advertising does not make a guide a product test, endorsement, or guarantee.
