How this edition works
This website provides editorial guides and browser-based calculators. Calculator inputs are not uploaded or saved by the calculator. The website is configured to use Google AdSense and Google Privacy & messaging. Optional Google Analytics 4 is configured as described below. No affiliate tracking, newsletter signup, user account, or contact form is installed.
Optional Google Analytics
We use Google Analytics 4 only after you select Allow analytics. Before that choice, or if you decline, this site does not load the Google Analytics tag. If enabled, Google processes page visits, browser and device information, referral information, and site interactions to help us understand use of this publication. We do not send calculator input values as analytics events. Page URLs and referrers are configured without their query strings or fragments. Google signals and advertising personalization features are disabled in this site configuration.
Your choice is stored locally in your browser for up to 180 days. You can change it using Analytics settings in the footer. Declining after allowing disables further Analytics collection on this site and removes its Google Analytics cookies where accessible; it does not erase data already received by Google. Browser storage restrictions or clearing site data may cause us to ask again. Advertising consent is managed separately through Google Privacy & messaging.
See Google’s privacy policy and Google’s Analytics opt-out information. Google Analytics may use cookies to distinguish visits after you consent.
Hosting and email
Serving a website involves technical information such as an IP address, requested URL, browser information, and request time. Your hosting provider may process this information for delivery, logs, and security. The publisher’s actual hosting configuration and retention settings determine the specific handling. If you email the publisher, your email provider and the publisher’s email service process the message and contact information.
Advertising and third-party technology
Third-party vendors, including Google, may use cookies and similar identifiers to serve and measure ads based on visits to this and other websites. Advertising services may process information such as an IP address, device/browser details, pages visited, and cookie or device identifiers. Other advertising partners may place or read cookies or use web beacons in connection with advertising. Available partners, purposes, and choices are described in the consent interface where applicable.
Learn how Google uses information from partner sites at Google’s partner-site information page. Google provides controls for personalized advertising through My Ad Center. You may also review third-party advertising choices at YourAdChoices. Non-personalized or limited advertising may still involve processing for delivery, measurement, security, or fraud prevention.
Privacy choices
A Google consent message is configured for visitors in the EEA, UK, and Switzerland, with consent, refusal, and management options. Use the Privacy and cookie settings link, when available, to revisit that choice. A Google US state privacy message is configured for supported US states and provides an opt-out link for sale or sharing of personal information for advertising. Available interfaces depend on location, platform support, and the messaging configuration. Contact the publisher about information you have sent directly.
Links and changes
External sites and your email application operate under their own practices. This notice will be revised if the site changes its advertising, forms, analytics, or other data-handling features.
