Your data
Private by default, clear by design
KarobarKit's current calculators, QR generators and document generators run locally in your browser. This page describes the current tool set and its data boundary.
What happens to calculator inputs
CAGR, ROI, business-economics, URL, UPI and document values are held in the page while you use a tool. QR payloads, payment URIs, document previews, CSV exports and PDF exports are generated in the browser. Selected logos are read and resized locally only; they are not uploaded. These values are not sent to a server, written into a URL, stored in an account or included in analytics. Business-economics tools offer an explicit “Save for a related tool” action; that opt-in handoff uses bounded session storage in the current tab, imports only matching fields after a second confirmation and clears when consumed or when the tab closes. Reloading otherwise clears the current form state.
Analytics boundary
The production site uses Vercel Web Analytics for aggregate page-view measurement. Query strings and URL fragments are removed before a page view is sent, so search text and other URL details are excluded. Analytics data is not sent in local development.
KarobarKit's separate product-event boundary remains browser-only and accepts only allowlisted, low-cardinality metadata such as a tool ID, category, export format or validation code. Financial values, names, UPI IDs, amounts, payment notes, logos, QR payloads, document contents and file data are forbidden properties and are not forwarded to Vercel Analytics.
Error handling
Route errors may carry a short framework digest in development diagnostics. Safe logging filters context to a feature name, code or digest; it does not log form values. If you report an issue, send only the tool name, version and a description without private data.
Future tools
Any tool that needs a network provider, persistent local storage, file upload or account will show that data flow before input. The Phase 2 handoff is temporary tab storage and is not an account or persistent profile. No assumption that a future tool is local-first should be made from this page.
