What this site stores
Calculators may save recent settings, a theme preference, and selected time zones in local storage on your device. That data does not leave the browser unless you submit the contact form.
Contact form
If you send a message, we receive the name, email, and message you typed so we can reply. Do not include sensitive personal data. Delivery uses a server-side webhook or email API configured by the operator; those keys are never shipped to the browser.
Hosting
The site may be hosted on Vercel or similar infrastructure. Hosts typically log IP addresses and user agents for security and reliability. We do not sell personal information.
