This website provides free financial calculators to help you think through housing and investment decisions. We are committed to being straightforward about data: this site does not create user accounts, does not require you to submit personal information, and does not store your calculator inputs on any server. All values you enter are saved only in your own browser's local storage and never leave your device.
That said, like most websites, we use standard third-party services for analytics and advertising that do collect certain information automatically. This policy explains what that means for you.
We do not collect, store, or transmit:
When you visit this site, third-party services we use may automatically collect certain technical information, including:
This information is collected through cookies and similar tracking technologies and is used to understand how visitors use the site and to serve relevant advertisements.
This site uses Google Analytics to understand how visitors interact with our tools — for example, which calculators are used most and how long visitors engage with them. Google Analytics collects data in anonymized, aggregated form. We do not use this data to identify individual visitors.
Google Analytics may use cookies and may transmit data to Google servers in the United States. Google's use of this data is governed by the Google Privacy Policy.
You can opt out of Google Analytics tracking across all websites by installing the Google Analytics Opt-out Browser Add-on.
This site displays advertisements served by Google AdSense and may display ads through other Google advertising products. These services use cookies to show you ads that are relevant to your interests based on your browsing activity on this site and across other sites on the internet. This practice is commonly referred to as interest-based or behavioral advertising.
Google's advertising cookies — including the DoubleClick cookie — allow Google and its partners to serve ads based on your prior visits to this site and other sites. Google's use of advertising cookies is governed by the Google Advertising Policies.
You can manage your ad personalization preferences through the following resources:
This site may contain links to third-party services — such as mortgage lenders, real estate platforms, or financial tools. If you click one of these links and make a purchase or submit an inquiry, we may receive a commission at no additional cost to you.
These third parties operate their own websites and have their own privacy policies and data practices, which we do not control. We only link to services we believe are relevant and useful in the context of the calculators on this site.
Cookies are small text files stored in your browser. This site does not set first-party cookies for tracking or advertising purposes. Third-party services (Google Analytics, Google AdSense) set their own cookies as described in the sections above.
Most browsers allow you to refuse or delete cookies through their settings. Disabling cookies may affect third-party features such as analytics and ad personalization, but will not affect the calculators on this site, which rely on your browser's local storage rather than cookies.
This site is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through this site, please reach out and we will take prompt steps to remove it.
We may update this policy from time to time to reflect changes in our practices or applicable law. When we do, we will update the effective date at the top of this page. We encourage you to review this page periodically. Your continued use of the site after any changes constitutes acceptance of the updated policy.
