What you type

All calculations run in your browser. Salaries, hours, deductions and other values you enter are not stored and are never sent to us, to Google or to anyone else.

Google Analytics

Google Analytics is used to understand which pages people use. The Google Analytics script is blocked until you choose “Accept analytics.” Before that choice, the site sends no Google Analytics script request, consent ping, or event. “Reject analytics” leaves Analytics unloaded. You can change or withdraw your choice at any time using Privacy settings (bottom of every page). Withdrawal stops future Analytics events, removes applicable first-party Analytics cookies, and reloads the page; it does not erase data already received by Google.

After acceptance, the site measures page views (the page address without query strings, and the page title), whether a calculator was used (a fixed label such as “paycheck”, never the numbers entered), and clicks on the contact email link. Standard Google Analytics session events may also be collected after opt-in. We do not send names, email addresses, free text, User-ID, calculator inputs or arbitrary query-string values. Only an explicit allowlist of campaign parameters may be included, and referrers are reduced to a short list of search engines and communities. GA4 uses first-party cookies (_ga, _ga_*) scoped to this hostname, with a 30-day cookie lifetime; this is separate from the two-month event and user-data retention setting in the property. The stored consent choice records accepted or rejected, a timestamp, and the notice version in this site’s first-party local storage. It is not sent to Google and is not an analytics identifier.

Advertising storage, advertising user data, and advertising personalization are denied in the tag and ads personalization is disabled for all regions in the property. Google Signals and user-provided data collection are off. No Google Ads link, remarketing, cross-domain tracking, or session replay is configured. Enhanced Measurement is disabled. Google Analytics can still collect information such as approximate location, browser/device information, and session statistics after opt-in. Google says IP addresses are not logged or stored by Analytics; this does not make Analytics data anonymous. See Google’s data collection information and privacy controls.

Google processes Analytics data under its service and account terms, and data may be processed in the United States. The Google Analytics account shows that Google Ads Data Processing Terms were accepted on May 15, 2021. This notice does not claim that the setup guarantees legal compliance. See Google’s Privacy Policy, data-transfer information, and Analytics data processing terms.

Cloudflare and hosting

Cloudflare provides the site’s DNS, hosting, delivery, and security services and may keep standard server logs (such as IP address, requested page and browser type) to operate and protect the service. No Cloudflare Web Analytics beacon is installed. See Cloudflare’s Privacy Policy.

Your rights

You can ask about, correct or object to processing of data concerning you by emailing the address above. Because we don't receive calculator inputs and Google Analytics data is not linked to names or emails, we usually cannot identify an individual visitor in it.
