Privacy Policy
TheProductivityCalculator.com is a single-purpose calculator that runs in your browser without requiring an account. This page explains what limited information is processed when you visit and how advertising and analytics work.

Advertising (Google AdSense)
We serve Google AdSense advertising units on the calculator homepage (/) and the Math & Methodology page (/math.html). These pages load the AdSense script so Google can fill ad slots. Informational pages such as About, Contact, Accessibility, Disclaimer, Terms, Sitemap, and Examples remain ad-free and do not request the AdSense script. If ad coverage expands to additional pages, we will update this section before the change goes live.
Google uses cookies, local storage, and device identifiers to deliver, personalize, and measure ads. Data captured can include your IP address, browser type, device information, and interactions with the ad units. Google's use of data is described in the Google Advertising Privacy Policy. ProductivityCalc.com does not share user-provided data with Google for ad targeting, and we do not permit Google to show personalized ads in sensitive categories prohibited by their policies.
You can manage how Google personalizes ads at adssettings.google.com. Visitors may also opt out of interest-based advertising from many providers at aboutads.info. When legally required (for example in the EEA or UK), Google presents a consent dialog before ads run; if you decline personalized ads we request non-personalized ad delivery.
Cookies & local storage
AdSense and Google Analytics set cookies or similar storage to keep track of ad delivery, prevent duplicate impressions, and measure aggregate traffic. You can clear or block cookies through your browser settings.
Analytics
We use Google Analytics (via Firebase Analytics) to understand aggregate, anonymous usage of the calculator. Analytics collects event data such as page views, device type, approximate location (city-level), and on-page actions. We review analytics in aggregate only and do not attempt to identify individual visitors. Google’s handling of this data is detailed in the Google Privacy Policy.
Data we do not collect
The calculator runs entirely in the browser. We do not create user accounts, store calculator inputs, or sell personal information.
