Privacy Policy
Last updated: April 17, 2026
What we collect
We do not ask you to create an account, and we do not collect or store the financial numbers you enter into the calculator. All calculations happen in your browser — the inputs never leave your device.
Local storage
Your light/dark theme preference is saved in your browser's localStorage
so the site remembers it on your next visit. This data stays on your device.
Analytics & third-party services
We use Google Tag Manager, which may load Google Analytics or similar measurement tools to help us understand aggregate usage (for example, pages visited and device type). These services may set cookies and may process data such as your IP address according to their own privacy policies.
You can learn more about how Google handles data at Google's privacy policy. You can block these tools by using your browser's privacy controls or a content blocker.
Hosting
This site is hosted on Vercel, which receives standard request information (such as IP address and user-agent) as part of serving the site. See Vercel's privacy policy for details.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the date above.
