Our privacy promise

CalcFlow is privacy-first by design. Every calculation runs entirely in your browser — the values you type never leave your device. We do not require an account, we do not sell or share personal data, and we do not show advertising on calculator pages.

Analytics — only with your consent

We use Google Tag Manager and Google Analytics 4 to understand which calculators and guides are useful. Analytics loads only after you grant consent in the cookie banner. Until you accept, no analytics scripts run, no analytics cookies are set, and no measurement data is sent.

What is stored on your device

The identifiers of the last few calculators you opened.
Your cookie consent choice (granted or denied).

Your rights (GDPR & CCPA)

Opt out of analytics at any time via the cookie banner or footer link.
We honour your browser’s Do Not Track signal — if DNT is on, analytics never loads.
We do not sell personal information, and we do not share data for cross-context advertising.
