Privacy Policy
Summary
Short version: your calculations never leave your device. This page explains what that means in detail, and what changes when advertising is enabled on the site.
What we do not collect
Hesaba requires no account and stores no personal information. The numbers you enter into any calculator are processed entirely by JavaScript running in your browser; they are not transmitted to us, not logged, and not visible to anyone but you. Closing the tab erases them. We do not sell data, and we have no data to sell.
Standard technical logs
Like virtually every website, our hosting provider may record basic server logs — IP address, browser type, pages requested — for security and reliability. These logs are used to keep the site online and are not combined with any calculation data, because no calculation data exists on the server side.
Advertising and cookies
If display advertising is enabled on this site in the future, advertising partners may set cookies or use similar technologies to serve and measure ads. Such partners operate under their own privacy policies, and where required by law the site will present consent options before non-essential cookies are used. You can also block or clear cookies through your browser settings at any time; the calculators work fully without cookies.
Local storage
The site may store one small preference in your browser's local storage — your chosen language — so redirects can take you to the right version. This preference stays on your device and can be cleared at will.
Changes
If this policy changes materially, the updated version will be published on this page with a revised date. Questions are welcome through the contact page.
