When a download is created, the new file is generated locally in the browser; when text or values are calculated, the input stays inside the open tab.
Privacy and local browser processing
The main benefit of Loan calculator is local processing. Your files or inputs are not uploaded to toolboxlib; they are handled with modern browser capabilities directly on your device.

Local processing also keeps many workflows fast. There is no upload queue, no remote file-size check and no account requirement. For very large files, speed depends on your device and available memory, but control remains with you. Practical calculators – instant and private in your browser.
