Here is how we handle data on ebill.info.bd. By using the site you accept what is described below.

• What you type into the calculator (units, category, load) stays in your browser. Nothing reaches our servers.
• Our host keeps standard server logs (IP address, user agent, referrer) so we can spot abuse.
• If you accept analytics cookies, Google Analytics 4 records anonymous data such as page views, device type, and country.
• Your language and theme choice live in your browser's localStorage, not on our side.

• Essential cookies keep the site working. They remember your language and your cookie choice.
• Analytics cookies are set by Google Analytics 4, and only after you accept them on the banner.
• Advertising cookies are set by Google AdSense for personalized ads, and only after you accept. You can switch off personalized ads at https://www.google.com/settings/ads.
• Changed your mind? Clear your site storage and the banner returns so you can choose again.
