Last updated: August 21, 2026. AssetCalculus (“we,” “us,” or “this site”) provides free stock and ETF calculators. This policy explains what information is involved when you use the site, and it applies to all pages on assetcalculus.com.
The Numbers You Enter Into Our Calculators
Every calculator on this site runs entirely in your own browser. Figures like dividend amounts, share prices, purchase history, or expense ratios that you type into a calculator are processed on your device using JavaScript and are never transmitted to, or stored on, our servers. If you close the tab, that data is gone.
Information Collected Automatically
Like most websites, our hosting provider and any analytics tools we use (such as Google Analytics) may automatically log standard technical details — your general location, browser type, device type, pages visited, and how long you stayed — to help us understand traffic and improve the site. This information does not identify you personally. If we add analytics or advertising in the future, this policy will be updated to reflect it.
Cookies
This site does not use cookies to store the numbers you enter into a calculator. If analytics or advertising tools are added later, they may set cookies to recognize repeat visits or serve relevant ads. You can view, block, or delete cookies at any time through your browser’s settings.
Information You Send Us Directly
If you email us directly, we keep that correspondence — including your email address and whatever you send us — only to respond to your message and for our own recordkeeping. We do not sell or share this information with third parties for marketing purposes.
Third-Party Links
This site may occasionally link to outside resources for further reading. We aren’t responsible for the content or privacy practices of any third-party site you reach through those links.
Children’s Privacy
AssetCalculus is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this policy as the site grows — for example, if we add analytics or advertising. Any changes will be posted on this page with a new “last updated” date.
