Privacy

Calculator inputs are processed locally in your browser. This application does not add advertising, analytics, accounts, or persistent calculation storage.

Tool links exclude inputs by default. If you choose to include inputs, they appear in the link’s address fragment and can be read by anyone who receives it. They are not encrypted and may remain in browser history. Existing query-based links may also expose values to server logs. Copied summaries and PNG images contain result amounts. Only share information you intend recipients to see. Currency conversion uses a manually entered rate or a dated snapshot bundled with the site. No external API requests are made.
