Buildarith legal
Privacy Policy
This policy explains the limited information involved when you use Buildarith and how calculator values are handled.
Effective date: July 28, 2026
Information we receive
Buildarith does not offer accounts, registration, contact forms, or paid subscriptions. We do not ask you to provide a name, email address, postal address, or payment information.
When your browser requests a Buildarith page, the systems used to deliver the website may automatically receive ordinary technical request information. This can include an IP address, browser and device type, requested URL, referring page, and request date and time. This information is part of normal website delivery and security operations. If you accept optional analytics, Google Analytics 4 may also receive technical information associated with page views.
Calculator inputs
Calculations run in your browser. Values you enter—such as dimensions, quantities, waste percentages, and optional prices—are processed locally to display a result. They are not submitted to a Buildarith server or stored in a Buildarith database.
Calculator values remain in the page's temporary memory while you use it. Reloading or closing the page normally clears them, because Buildarith does not save those inputs in cookies, localStorage, or sessionStorage.
Service providers and sharing
Google Analytics 4 is a third-party analytics service that loads only after analytics consent. Buildarith has no advertising, payment, account, or embedded-content integrations. Infrastructure providers involved in hosting and transmitting the site may process technical request information as needed to deliver and protect the service.
Buildarith does not sell personal information. We may disclose information if reasonably necessary to comply with applicable law, protect the service or its users, or address security and abuse.
Retention
Buildarith does not retain calculator inputs. The site's code does not define a retention period for technical request logs maintained by hosting or network infrastructure, so we do not claim a specific period.
Security
We use reasonable measures appropriate to a public informational website. No internet transmission or system can be guaranteed to be completely secure, and Buildarith cannot promise absolute protection against every risk.
Your privacy choices and rights
You can choose not to enter information into a calculator, clear the page by reloading it, and use browser controls to block or delete site data. Because Buildarith has no accounts and does not retain calculator inputs, it generally has no calculator-input record to access, correct, or delete.
Depending on where you live, privacy law may provide rights relating to personal information. You may exercise available rights through any contact method Buildarith publishes in the future. No public contact channel is currently listed on the site.
Children’s privacy
Buildarith is a general-audience construction planning service and is not directed to children. We do not knowingly request personal information from children.
International use
Buildarith is available on the internet and may be accessed outside the United States. If you use the site from another country, technical request information may be processed in locations used by the infrastructure that delivers the site. You are responsible for considering local rules that apply to your use.
Changes to this policy
We may update this Privacy Policy when the site or its practices change. The effective date at the top will identify the current version. Material changes will be presented on this page or elsewhere on the site as appropriate.
