Privacy Policy
The short version
The calculator on this site runs entirely in your browser. The figures you type in are never transmitted to us, never stored on our servers, and never shared. We do not ask you to create an account and we do not collect your name, address, Social Security number, or any tax identifiers.
Information we do not collect
We do not collect personal or financial information through the calculator. Your mileage, lodging, meal, and income entries exist only in your own browser session and disappear when you close the page.
Information collected automatically
Like most websites, our hosting infrastructure and analytics may record standard technical information such as your IP address, browser type, device type, referring page, and the pages you visit. This is used to understand traffic patterns and keep the site working.
Cookies and advertising
This site is supported by advertising and affiliate referrals. Advertising partners, which may include Google and its partners, may set cookies or use similar technologies to serve and measure ads, including personalized ads based on your prior visits to this and other websites.
You can opt out of personalized advertising from Google at google.com/settings/ads, and you can opt out of personalized advertising from many other vendors at aboutads.info. Most browsers also let you block or delete cookies in their settings.
Affiliate links
Some outbound links to tax-preparation services are affiliate links. If you follow one and file a return, we may receive a commission at no additional cost to you. Those services may set their own cookies to attribute the referral. Their handling of your data is governed by their own privacy policies, not this one. Affiliate relationships never influence the figures the calculator produces.
Third-party sites
We link to external resources such as IRS.gov and GSA.gov, and to tax-filing services. We are not responsible for the privacy practices or content of any site we link to.
Children
This site is intended for adults and is not directed to children under 13. We do not knowingly collect information from children under 13.
Your choices
Because we do not collect personal information through the calculator, there is generally no account or personal record for us to retrieve, correct, or delete. If you have a question about data related to your use of this site, contact us using the details on our contact page.
Changes
We may update this policy as the site changes. The revision date at the top reflects the most recent version.
