Every Coinsum calculator runs entirely in your browser. The amounts, prices and rates you type are never sent to us or stored anywhere. Coinsum has no accounts, sign-ups or forms.
Advertising
Coinsum is free because it shows ads. These ads may come from third-party networks, such as A-ADS. Those networks may use cookies or similar technologies, or collect standard technical data like your IP address, browser type and the pages you view. They use this to serve ads and measure performance. Their own privacy policies govern that data. You can block or delete cookies in your browser settings.
Hosting and fonts
The site is hosted on Cloudflare, which may process standard request logs for security and performance. Fonts are loaded from Google Fonts.
Not financial advice
Coinsum's results are estimates for educational purposes only. They don't account for taxes, slippage or changing rates, and they are not investment, tax or financial advice.
