Calculator inputs are sent to our server to produce your result. The calculation service does not save these inputs in a database or use them to create a profile. This version has no accounts, advertising scripts, analytics scripts or tracking cookies. Basic request information is used to enforce calculation rate limits.
If you choose “Copy calculation link”, the share link contains the entered settings in its URL. Anyone you share that link with can read those settings. Do not put personal or confidential information in calculator inputs or shared links.
The server hosting the website may process ordinary request information, including IP address, request path, browser information and access time, for serving pages and operational logs. A request for a shared URL can include its query string in those logs.
App Store links open Apple’s website. Their privacy practices apply there. The mobile apps have their own privacy policies linked from their App Store pages.
