Privacy Policy

10. California residents (CCPA / CPRA).

If you are a California resident, the California Consumer Privacy Act, as amended by the California Privacy Rights Act, gives you the right to know what personal information we collect, to request deletion of personal information we have collected from you, to request correction of inaccurate personal information, and to opt out of any “sale” or “sharing” of personal information for cross-context behavioral advertising.

We do not sell personal information for money, we have no data broker relationships, and we have no financial incentives program. Personal information shared with advertising partners to display ads can be limited through the controls described in section 2, and exercising your rights will not result in any denial of service or change in price.

The categories of personal information we collect are set out in section 1: contact form identifiers (name and email address) and the content of your message, plus the standard technical data described above. We collect them for the business purposes described in section 3. We do not collect sensitive personal information. To submit a California request, use the contact form on the contact page; an authorized agent may submit a request on your behalf with proof of authorization. We will respond within the period required by the CCPA and will not discriminate against you for exercising your rights.

11. EEA, UK and Swiss visitors (GDPR).

If you are in the European Economic Area, the United Kingdom, or Switzerland, our legal basis for processing the technical data described in section 1 is our legitimate interest in operating a secure, reliable website and understanding which calculators are actually used. Our legal basis for processing contact form submissions is your consent, given when you choose to send the message, and where applicable our legitimate interest in responding to correspondence.

You have the right to access, rectify, or erase your personal data; to restrict or object to processing; to data portability; and to lodge a complaint with your local supervisory authority. Because we retain no account records and no analytics identifiers tied to your identity, the practical result of most requests is a written confirmation that we hold nothing attributable to you. Send requests through the contact page.

12. Other U.S. state privacy laws.

Residents of Virginia, Colorado, Connecticut, Texas, and other states with comprehensive privacy statutes may have similar rights to access, delete, correct, and obtain a copy of personal data, and to opt out of sale, targeted advertising, or certain profiling. We do not sell personal data, and we do not profile you for decisions that produce legal or similarly significant effects. Requests from residents of those states are handled the same way as California requests, through the contact page.

13. Your cookie and tracking choices.

You can block or delete cookies through your browser settings at any time; blocking first-party analytics cookies does not limit any functionality on this site, because no calculator requires a cookie to run. Google provides a browser add-on that prevents Google Analytics from sharing your activity with us, and Google’s ad settings page lets you control personalized advertising across Google properties.

We also honor recognized opt-out preference signals where applicable to the analytics and advertising we run. If advertising is enabled on this site, disclosure is added to this section and to the terms of use before the first ad is served, and consent requirements will be met before any non-essential cookie is set.

14. Data retention.

Contact form messages are not written to a database by this site; they are passed to the form processor and then to our inbox. We retain correspondence only as long as needed to resolve the request and for a short record-keeping period afterward, after which it is deleted. Google Analytics keeps aggregated traffic data for a limited period and then purges the underlying records automatically. We do not keep server-side access logs beyond what our hosting provider retains for security purposes.

15. International transfers.

This site is hosted and operated in the United States, and Google Analytics processes data on Google’s infrastructure. If you visit from outside the United States, your technical data will be transferred to and processed in the United States, where privacy laws may differ from those in your jurisdiction. Where a transfer mechanism is required, we rely on the safeguards Google makes available for such transfers and on the fact that the data transferred is the non-identifying technical data described in section 1.

16. How to make a privacy request.

Send any privacy request through the form on the contact page, with the subject line “Privacy request.” Tell us which right you want to exercise and the jurisdiction you are in, so we can apply the correct standard. We may ask you to confirm the email address you used so we do not disclose anything to the wrong person. We answer privacy-related inquiries within five business days, and we will tell you plainly if we hold no data attributable to you.
