Calculator inputs
Calculations run in your browser. Calculator input values are not sent to or stored on our calculator server. Copying a result or including it in a comment may disclose it according to the action you take.
Favorites
Only calculator identifiers are saved in your browser’s localStorage for favorites. No separate site account is created. Remove favorites or clear this site’s browser data to delete them.
Access logs and statistics
Hosting and security services may process IP addresses, browser details, request URLs and access times. The site uses WordPress.com/Jetpack Stats by Automattic for visitor statistics. This is separate from storing calculator input values.
Advertising and cookies
Google AdSense code is connected. Ad delivery depends on approval, settings, location and consent where applicable. Google and advertising partners may use cookies or similar technology for ad delivery and measurement. Manage choices through the consent message when shown and your browser’s cookie settings.
Contact comments
Nicknames, comment text and connection information are used to handle inquiries and prevent spam. Approved comments are public. Do not post phone numbers, email addresses, identity documents or sensitive evidence. Calculator pages do not accept comments.
Retention, deletion and requests

Providers’ policies govern their hosting, statistics and advertising data. You can request access, correction, deletion or restriction through contact comments. Initially provide only the comment date, nickname and type of request.
