Privacy

Your calculator inputs and saved comparison stay in memory in the current browser tab. We do not send financial amounts to a calculation server, add them to analytics, store them in cookies or local storage, or include them in URLs. Reloading or closing the page clears this calculator state.

Regional routing

Cloudflare processes the connection IP address and provides a country estimate. We use that country code to redirect the root homepage to India or the United States. This routing code does not write the IP address or country to our referral dataset. We do not ask for device location or use GPS. Regional tool URLs remain accessible regardless of location.

Hosting and connection data

Cloudflare delivers and protects this website and may process connection information, including IP addresses and request URLs, as part of hosting and security. GitHub hosts our source repository and deployment pipeline. The statement that calculator inputs stay in the browser does not mean our hosting provider receives no connection data.

Page and referral measurement

For successful public document requests, our Worker counts an approved finance page category and a bounded source label using Cloudflare Analytics Engine. The label can be ChatGPT, Google, Bing, DuckDuckGo, Perplexity, or direct-or-other. A labelled utm_source=chatgpt.com takes precedence; otherwise only an allowlisted referrer hostname is classified. Internal referrers and prefetch requests are excluded where identified.

These counts do not store financial inputs, arbitrary query parameters, full referrers, IP addresses, or visitor IDs. They count classified page requests, not unique people, verified search clicks, or verified AI recommendations. Missing referrers cannot reliably distinguish direct visits from other sources. We do not add a separate browser tracking script in this application.

Downloads and external links

CSV downloads are generated locally. If you share a downloaded file, its contents can be read by the recipient. Links to educational sources open third-party websites with their own privacy practices. We do not require an account and do not currently run advertising on this finance site.

Appearance and your browser

Light and dark appearance follow your device preference. No preference cookie is required. Your browser or extensions may retain page history and downloads according to their settings. Clearing this site's browser data does not remove CSV files you previously saved.
