About Know

Useful answers, tools and daily information — fast.

Our Core Product Vision

Know is built to deliver fast, instant, and reliable utility tools, financial calculators, date tools, currency rates, and India-specific datasets. We answer your search intent in one fast, mobile-first page without bloat or mandatory sign-ups.

Parent Brand & Ownership

Know is developed, published, and maintained by SonBarsa, a global digital agency delivering AI, web, mobile, and cloud solutions since 2008 across India, the UK, and the Middle East.

100% Free & Privacy-First Architecture

We prioritize client-side calculations and static Cloudflare CDN distribution. We do not track sensitive personal information, do not require user accounts for core utilities, and operate using verified open data sources.

Data Sources & Accuracy

All financial algorithms follow standard formulas used by Indian banking institutions (RBI, SBI, HDFC). Foreign exchange rates are sourced from the European Central Bank via Frankfurter API under open database licensing.
