Privacy policy
How calculator fields, site requests and configured services are handled.
Calculator inputs
Calculator fields are processed locally in JavaScript. Changing watts, hours, rates, duty cycle or annual-use days does not submit those field values to our server. Site searches are separate: a search request includes its query in the URL.
Server logs
Our web host records standard access logs, which include IP address, requested URL, referring page, user agent and timestamp. Requested URLs can contain site search terms. These records support security and diagnosis of technical faults.
Analytics and your setting
Google Analytics runs by default on costtorunit.com to measure page visits and traffic sources. It uses first-party cookies and sends event-level usage data to Google, including page paths, the referring website, country or region, and visit or session events. Google uses that information to produce reports. Google Signals, granular location and device collection, advertising personalization, user-provided-data collection and form-interaction measurement are disabled.
Our analytics code does not send calculator or planner field values. Internal site-search pages
(/search) are excluded from analytics. The page URL configured for analytics omits its
query string and fragment, the referring URL is reduced to its website origin, and page titles in
reports use the page path. Search requests can still appear in the server logs described above.
The Analytics property is configured to retain event and user data for two months, without resetting user-data retention when new activity occurs. Standard aggregated reports have different retention rules. Email and common site-search query parameters are also configured for data redaction.
Use Analytics choices in the footer to turn analytics off or on. An explicit setting is saved in this browser for 180 days. Turning analytics off disables this tag, attempts to remove accessible first-party Analytics cookies, and reloads the page, clearing any unsaved calculator entries. An open page where analytics is off stays off if its setting expires; a later page load returns to the default-on behavior once the 180-day setting has expired or site storage has been cleared.
If the browser cannot save settings, this implementation keeps analytics off on the current page. A failed change cannot reliably apply to later visits. When an Off setting cannot be saved, the page stays open with analytics disabled and displays a message instead of automatically reloading.
Analytics cookies are configured for up to 180 days without extending their lifetime on every page load. Turning analytics off does not recall data already sent to Google. Cookie removal is limited to cookies this page can access and the standard Analytics cookies on its host and ancestor paths; it cannot remove cookies hidden from JavaScript, on unrelated paths or subdomains, or outside this implementation. Google describes its processing in its privacy policy and information about partner sites.
Local storage
We store your light or dark theme preference in your browser’s local storage so the site remembers it. This never leaves your device and contains nothing identifying.
The separate ctr-analytics-preference record stores only an explicit On or Off setting,
its timestamp and its 180-day expiry. It contains no visitor identifier. A first visit does not create
a saved On setting; analytics uses the default described above. A temporary local-storage check confirms
that the browser can save settings before analytics starts.
