We Collect Nothing
FinKit is designed from the ground up with a simple principle: your financial data is yours, and it should stay on your device. Every calculation — debt payoff projections, loan comparisons, FIRE number estimates — happens entirely in your browser using JavaScript.
We do not use cookies. We do not use analytics. We do not have a database. We do not have user accounts that store information. There is no server-side processing of your financial inputs. When you close the tab, everything is gone.
What Happens When You Use FinKit
- You open a calculator page — the HTML, CSS, and JavaScript load from our server (Vercel).
- You type numbers into input fields — those numbers stay in your browser's memory.
- You click calculate — JavaScript running locally performs the math and updates the page.
- You close the tab — all data is purged from memory.
At no point are your numbers transmitted to us, stored on a server, or shared with third parties. We have no way to see what you type.
Hosting and Infrastructure
FinKit is hosted on Vercel. Vercel may collect standard server logs (IP address, request path, timestamp) for operational purposes. These logs are not linked to your financial inputs and are automatically purged. We do not have access to them in a way that would identify individual users.
Open Source — Verify It Yourself
FinKit is fully open source under the MIT license. You can inspect every line of code on GitHub. If you prefer, you can clone the repository and run FinKit entirely offline on your own machine. There is no hidden tracking, no obfuscated code, and no surprise data collection.
Changes to This Policy
If this policy ever changes, the update will be reflected here with a new date. The core promise — no data collection, no tracking, no accounts — is fundamental to FinKit and will not change.
