Privacy Policy
Calculator inputs are processed locally in your browser and are not stored by BusinessMathKit.
Calculator information
Prices, revenue, costs, margins and other calculator inputs are kept in temporary browser memory. We do not save them in a database, cookies, localStorage or sessionStorage. We do not send them to a server, analytics provider or AI service to perform calculations. Refreshing the page resets the inputs. Only your light/dark theme preference is stored locally on this device; it is not sent to us.
Copying and downloading results
Copy and Download TXT work on your device. They put the displayed result in your clipboard or a file you choose to save. We do not receive that export. Anyone you share the text with may see the financial figures it contains.
Website requests and hosting
Loading a website involves requests to its hosting provider. Ordinary technical records may include IP address, requested page, request time, browser details and security-related information. Hostinger, the hosting provider for this release, may process those records to deliver and protect the site. This is separate from calculator input processing. We do not claim that using the website creates no technical data.
Optional services are currently disabled
This release does not enable optional analytics, advertising, AdSense or affiliate tracking. No optional-tracking consent banner is shown because those services are not active. If such services are introduced, this policy and the consent arrangements will need to be updated before activation. Calculator business inputs must remain excluded from analytics events.
Advertising preparation
Advertising positions are prepared but disabled: no Google advertising code or advertising cookies are loaded by this application. Before ads are activated, this notice must identify the providers actually used, explain their cookies and data use, and offer the applicable consent and advertising-choice controls. Preparing a position does not mean ads are currently running.
Messages and external links
If you email us, you choose which information to send. Your email provider and the receiving provider process that correspondence under their own policies. External websites linked from this site operate independently. Do not include confidential business records or sensitive personal information when a fictional calculation example can explain your question.
Questions and changes
For privacy questions, email kh.aljadadi@gmail.com or use the email link on the Contact page. This policy describes the current calculator application. Changes to hosting, contact services or optional integrations may require an updated notice. Last updated: 2 October 2026.
