Calculation inputs
The calculators perform arithmetic in your browser. This version does not send entered mass, volume or target amounts to an API, analytics service or calculation server. There are no accounts or advertising trackers in the application.
Clipboard and local state
Copy result and Copy report write text to your clipboard only after you press the respective button. Clipboard access may require browser permission. This version does not persist input history in localStorage; refreshing the page resets the form.
Hosting and email
Loading any webpage sends ordinary requests to its hosting service, which may process network metadata for delivery and security. The public website does not require an account.
Messages you choose to email to our contact address are forwarded by Cloudflare Email Routing to the project mailbox. Only include information needed to explain the issue; do not include personal health details. The report form itself does not send email.
Future changes
If accounts, analytics, advertising or cloud storage are introduced, this policy must be updated to describe those actual features before use.
