Privacy Policy
Last updated: 8 May 2026
Here is how we handle data on ebill.info.bd. By using the site you accept what is described below.
What we collect
- 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.
Cookies and similar technologies
- 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.
