Airport Math (“we,” “this site”) is a personal side project operated by Carolyn Donnelly. This privacy policy explains what information is collected when you use airportmath.com and how it’s used.
What We Collect
Airport Math itself does not collect or store any personal information. The calculator runs entirely in your browser — your flight time, airport, and drive time are never sent to our servers.
However, we use third-party services that may collect data automatically:
- Google Analytics (via Google Site Kit) — We use Google Analytics to understand how visitors use this site. Google Analytics collects information such as your IP address, browser type, pages visited, time spent on the site, and general geographic location. This data is collected via cookies and is processed by Google. You can learn more at policies.google.com/privacy, or opt out using the Google Analytics Opt-out Browser Add-on.
- Cookies — Google Analytics sets cookies in your browser to distinguish visitors and track sessions. You can control cookies through your browser settings.
Feedback Form
If you submit feedback using the “Report a Bug” or “Suggest a Feature” form, your message is sent to and stored by Formspree. We only receive the text you type — no account or personal information is required.
Affiliate Links
This site contains affiliate links to third-party services (such as SpotHero, Hotels.com, and Kayak). If you click these links, those companies may set their own cookies and collect data per their own privacy policies. We may earn a small commission at no cost to you.
Advertising
We may display ads on this site served by Google AdSense. Google may use cookies to show you ads based on your prior visits to this and other websites. You can opt out of personalized advertising at google.com/settings/ads.
Your Rights
California residents (CCPA): You have the right to know what personal data is collected about you, request deletion, and opt out of the sale of personal data. We do not sell your personal data. To make a request, contact us at the email below.
European visitors (GDPR): You have the right to access, correct, or delete any personal data held about you, and to object to or restrict processing. Because we use Google Analytics, some data may be processed in the United States. By using this site you acknowledge this. To make a request, contact us at the email below.
Children’s Privacy
This site is not directed at children under 13 and we do not knowingly collect any information from children.
Changes to This Policy
We may update this policy occasionally. Changes will be posted on this page with an updated date at the top.
