Privacy Policy
Short version: we collect almost nothing.
Data you provide
Calculator inputs are processed entirely in your browser. They are never sent to a server. When you close the tab, your inputs are gone (unless you've shared a URL containing them — see below).
Local storage
We use your browser's localStorage to remember two preferences across visits:
- Theme choice (light / dark).
- Display currency (USD, EUR, GBP, CNY, JPY, INR).
You can clear these at any time from your browser settings.
Shareable URLs
Each calculator can encode its current inputs into a URL fragment (the part after #). Fragments are not sent to any server. If you share such a URL with someone else, they will see the inputs you encoded.
Analytics
We count page views in aggregate — nothing else. FinCalc uses Cloudflare Web Analytics, which reports anonymous, aggregate statistics: pages viewed, approximate country, referring site. It sets no cookies, stores no personal data, and cannot identify you. Your calculator inputs never appear in it — they never leave your browser at all.
There is nothing beyond that: no cross-site trackers, no session recording, no advertising pixels. If any of this ever changes — new analytics, cookies, or advertising — this page will be updated and the change will be dated below before it ships.
Cookies
We do not set any cookies — the analytics above works without them.
Changes
If we change anything material, we'll update this page and bump the date below.
Last updated: September 1, 2026 — Analytics section rewritten to accurately describe the anonymous, cookie-free page-view statistics FinCalc runs.
