Privacy Policy

Last updated: July 31, 2026

This policy explains what happens to information when you use BizArith and its business calculators.

Information you provide

BizArith does not currently offer accounts, paid subscriptions, contact forms, newsletter sign-ups, or other features that ask you to submit personal information.

The numbers and selections you enter into a calculator are processed in your browser. All ten current calculators call calculation code included in the web page. The entered values are not sent to a BizArith backend, and BizArith does not save them in cookies or browser storage. Reloading or leaving a calculator page may clear your entries.

Technical data used to deliver the site

Like most websites, the hosting and network infrastructure that delivers BizArith may automatically process standard technical data. This can include an IP address, browser and device information, the requested page, request time, and security or server-log data.

This infrastructure-level processing helps return pages, maintain security, and diagnose service problems. BizArith does not ask you to provide this data through the calculators, and the current application does not use it to build user profiles.

Analytics, advertising, and communications

BizArith does not currently include analytics or advertising scripts. It does not use email marketing, and it does not provide user accounts or authentication. No third-party embeds are included in the current site.

Cookies and browser storage

The current BizArith application does not set its own cookies and does not use localStorage, sessionStorage, or IndexedDB to retain calculator values or preferences. For more detail, see the Cookie Policy.

External links

The current site does not include third-party embeds or integrations. If BizArith links to an external website, that website operates under its own terms and privacy practices. Review those practices before providing information to the external site.

Security

BizArith limits privacy risk by not asking for accounts or sending calculator inputs to a BizArith backend. Reasonable technical safeguards may reduce risk, but no website or transmission method can be guaranteed completely secure.

Children

BizArith is a general business-information site and is not directed specifically to children. The site does not knowingly ask children to create an account or submit personal information through a form.

Changes to this policy

This policy may be updated when the site, its technology, or its practices change. The date at the top of this page shows the latest revision.
