Calculator inputs stay in your browser
Values entered into the calculators are processed locally in your browser. They are not sent to a CalcQuick database, and you do not need an account.
Basic hosting records
Like most websites, the hosting platform may keep short-lived technical logs such as request time, page address, IP address and browser information for reliability and security. These records are separate from the optional analytics described below.
Optional Google Analytics
With your permission, CalcQuick loads Google Analytics (measurement ID G-VVLPMH51X7) to understand page visits, referral sources and performance across device types. Google may process the page URL and title, referrer, approximate location derived from the IP address, browser and device information, session identifiers and interaction events. Calculator values are not intentionally included. Advertising storage, user-data and personalization signals remain denied in this implementation.
With consent, calculator events record the tool, language, selected percentage mode, valid or invalid calculation status, copying, optional yes/no feedback and related-tool clicks. A short Spanish percentage-page text test stores only an A/B assignment in this browser until 9 December 2026. Input values and calculated results are not sent with these events. Declining clears the assignment and stops this measurement.
Your analytics choice
Google Analytics stays blocked until you select “Accept analytics”. Your choice is remembered in your browser’s local storage. The controls are on this privacy page, with no automatic pop-up. Use “Analytics settings” in the footer to return here and change or withdraw your choice; declining does not affect any calculator.
Analytics settings
With your permission, Google Analytics measures page visits and performance across device types. We also measure calculator use, selected modes, copy actions, optional feedback and short text experiments. Calculator inputs and results are not sent.
Optional analytics is off. You can keep using every calculator without enabling it.
