Everything you type into the calculator stays in your browser. Numbers you enter are never sent to a server and are never stored by this site. Third parties such as analytics and advertising providers may still set cookies when you visit, as described below.
The calculators on this site run entirely in your web browser using JavaScript. Starting amounts, contributions, interest rates, time horizons, and fund selections are processed on your own device. This information is not transmitted to us, not written to a database, and not retained after you close the page. If you download a CSV of your results, that file is generated locally by your browser and saved directly to your device.
Like most websites, this site and the services it uses may automatically receive standard technical information when you visit, including your IP address, browser type and version, device type, operating system, referring page, pages viewed, and the date and time of your visit. This information is used to understand general traffic patterns, diagnose problems, and keep the site secure.
Cookies are small text files placed on your device. This site may use them, and permits certain third parties to use them, for the following purposes:
You can control or disable cookies through your browser settings. Blocking cookies will not prevent you from using the calculators, since they do not depend on cookies to function.
This site may use third-party analytics services to measure traffic and usage. These services collect information such as pages visited, time on site, approximate geographic region, and referral source. They do not receive the values you type into the calculators.
This site may display advertising served by third-party advertising networks, including Google AdSense.
Some links on this site may be affiliate or referral links. If you click one and open an account or make a purchase, this site may receive a commission at no additional cost to you. Affiliate relationships never change the calculations this site performs, the historical data it displays, or the order in which funds are listed. Any page containing affiliate links will disclose that fact on the page itself.
If you send a message using the contact details on this site, we receive your email address and whatever you choose to include in your message. That information is used only to reply to you and is not sold or shared for marketing purposes.
Calculator inputs are never retained, because they are never received. Correspondence you send is kept only as long as needed to respond and maintain a reasonable record. Aggregate analytics data is retained according to the retention settings of the analytics provider in use.
This site is intended for a general adult audience and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, please contact us and we will delete it.
Depending on where you live, you may have rights to access, correct, delete, or restrict processing of personal information about you, and to opt out of certain data sharing. Because this site does not build user profiles or maintain accounts, in most cases we hold no personal information about you beyond any email correspondence you have initiated. To make a request, use the contact page.
Residents of the European Economic Area, the United Kingdom, and certain U.S. states including California may have additional rights under laws such as the GDPR, UK GDPR, and CCPA/CPRA. Requests will be handled in accordance with applicable law.
This site links to external websites, including brokerages, fund providers, and reference sources. We are not responsible for the content or privacy practices of those sites. Review their policies before providing information to them.
This site is served over HTTPS. No system can be guaranteed completely secure, but because the site holds no accounts, passwords, or stored financial information, the amount of data at risk is minimal by design.
This policy may be updated from time to time. Changes take effect when posted, and the "last updated" date above will change accordingly. Material changes will be noted more prominently.
Questions about this policy can be sent through the contact page.
