What leaves the device — and what does not
The calculator is the product. Your SIP dates are not.

Cash flows stay local
Dates and amounts you type, paste, or load from the sample are processed in JavaScript on your device. They are not sent to XirrRupee servers — we do not run an application backend. A draft of the ledger is saved inlocalStorage under xirrrupee.flows.v1 so a refresh does not wipe the table. Clear the site data in your browser, or use Clear on the calculator, to delete it.
No account, no cookies required
The calculator does not set an authentication cookie. If you never click a third-party ad or analytics script, there is nothing to consent to for the core tool.
Hosting and logs
The static files are meant to be served on Cloudflare Pages (or any static host). The host may record standard request logs — IP address, user agent, referrer — according to its own policy. Those logs are not joined to your cash flows, because the cash flows never arrive.
Advertising
Slots on the page are AdSense-ready. When a publisher ID is configured, Google may use cookies or advertising identifiers as described in Google’s privacy policy. Until that ID is set, the boxes are empty placeholders.
Contact mail
If you write to hello@xirrrupee.com, we receive whatever you put in the message. Use that inbox only for site issues, not folio statements.
Your choices
- Use the calculator offline after the first load (it is a static page).
- Disable JavaScript — you will see the articles, not a computed rate.
- Block third-party scripts if ads are enabled.
