Current data handling
The calculator logic runs in your browser. The site does not currently include an account system, database, contact form, advertising network or third-party analytics script. Calculator values and imported CSV text are not intentionally transmitted to the site operator.
Hosting logs
The hosting provider may process standard request information such as IP address, requested page, browser details and timestamps for security and service operation. Its own privacy terms apply.
Local storage and offline cache
A service worker may store static site files on your device so calculators work offline. You can remove this data using your browser's site-data or application settings. The current version does not store calculator input values.
Future monetisation
If analytics, advertising, affiliate links or a digital product platform are enabled later, this notice must be updated before those services go live. Consent controls may also be required depending on the technology and visitor location.
Contact
Use the contact page after the site owner adds a public support address.
