Two products, two privacy stories

This website (what you're on now)

• No accounts. There is nothing to sign up for.
• No analytics, no trackers, no ads, no third-party scripts. The calculators run entirely in your browser with plain JavaScript.
• No server-side storage. This is a static site — numbers you type into a calculator are used to compute a result in your browser and are never sent anywhere.
• No cookies, no localStorage for your inputs. Refresh the page and everything you typed is gone — deliberately, so the "nothing is saved" claim is literally true, not just a policy promise.
• Standard GitHub Pages hosting logs (IP address, requested page) may be retained by GitHub itself for operational purposes — this site has no visibility into or control over those, the same as any GitHub Pages site.

The mobile app

The app is a separate, private codebase with its own hard rules, carried since its first line of code:

• No backend, no accounts, no analytics, no crash reporting, no third-party SDKs. The only network calls the app makes are two official currency-rate feeds (European Central Bank, UN Treasury) and, only if you turn on the optional AI/LLM switch and choose a downloadable model, a one-time download of that model's file — nothing about you is in any of those requests, and nothing you type is ever sent anywhere.
• Never bank-linking, OAuth, or credentials. All your money data is typed in by you.
• Your data lives only on your device, in local on-device storage, and never leaves it.
• Export or delete everything, anytime — a single screen in the app (Manage → Your data) does both.

The app's full, official privacy policy is at bpupadhyaya.github.io/privacy-plainmoney.html. If anything on this page ever differs from it, that policy is the one that applies.

Why two different approaches

A public website can't securely hold anyone's real financial details — anything typed into a browser session is, at best, as private as that browser tab. The app can, because it never transmits anything: your real numbers stay in local storage on hardware you control, protected by your device's own lock screen and encryption, with no server anywhere in the picture to breach, subpoena, or misconfigure. That's the actual reason to use the app for anything you want to keep private — not a marketing claim, an architectural one.
