3. Log Files
We do not store, maintain, or collect any server logs or visitor activity records on our servers. Your IP address, browser information, and calculator interactions are completely private and are never logged or stored.
4. External Websites
Our site may contain links to external web resources. calculate.best is not responsible for the privacy practices, content, or terms of service of third-party websites. We encourage you to read the privacy statements of any website you visit.
