Privacy Policy

Last updated: October 28, 2026

BizCalcTool calculates in your browser. Product costs, salaries, tax figures and cash-flow inputs are never transmitted to us.

What we store

One localStorage flag (bizcalctool_cookie_ok) records that you dismissed the cookie notice. Nothing else is written to your device by us.

Cookies and advertising

We use a lightweight traffic counter and, where enabled, Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on prior visits to this and other websites. You can opt out of personalised advertising at Google Ads Settings.

Financial data

Because no calculation leaves your device, we hold no financial records about you. There is no account, no database and no export feature that contacts a server.

Data security

Because calculations never leave your device, there is no central store of salaries, revenue or product costs to breach. Pages are served over HTTPS; the only stored value is the local cookie flag.

Analytics

We count page views in aggregate — which calculators are used, not who used them. No session recording, no keystroke capture, no cross-site profile is built from your inputs.

International visitors (GDPR)

For EEA/UK visitors, the lawful basis for analytics and advertising cookies is consent, managed through the notice and your browser settings.

California rights (CCPA)

We do not sell personal information. Advertising providers may share data for cross-context behavioural advertising; opt out via Google Ads Settings or Global Privacy Control where supported.

Children

BizCalcTool is a business tool for adults and does not knowingly collect data from children under 13.
