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 — that data stays in your browser and is never sent anywhere. Our hosting provider, analytics tools, and any advertising we display may set cookies of their own, as described below. You can view, block, or delete cookies at any time through your browser’s settings, though blocking them may affect how some parts of the site behave.
Advertising
AssetCalculus may display advertisements served by third-party vendors, including Google. These vendors, including Google, use cookies (such as the Google DoubleClick DART cookie) to serve ads based on a visitor’s prior visits to this site or other websites on the internet. Google’s use of advertising cookies enables it and its partners to serve ads to visitors based on their visit to this site and/or other sites.
Visitors may opt out of the use of cookies for personalized advertising by visiting Google’s Ads Settings. Alternatively, visitors can opt out of some third-party vendors’ use of cookies for personalized advertising by visiting www.aboutads.info. We do not control the cookies these third parties set and are not responsible for their individual privacy practices — see their own privacy policies for details.
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.

Advertising Consent and Privacy Choices
If advertising is enabled, visitors in regions where consent is legally required may be shown a consent message before advertising cookies or similar identifiers are used. Depending on location and available choices, visitors may be able to consent to personalized advertising, choose non-personalized or limited advertising, reject optional purposes, or revisit their privacy choices.
Google and its advertising partners may process device information, cookie identifiers, approximate location, and interaction data for ad delivery, measurement, fraud prevention, and—when permitted—personalization. Available controls and participating providers will be identified in the applicable consent message. This policy does not override the choices presented in that message.
Consent Withdrawal
Where required, a privacy-choice or consent-revocation link will be made available through the site’s consent interface so visitors can revisit their selections.
