Privacy Policy
At CalcHub, your financial privacy is absolute. Here is how our 100% client-side architecture guarantees your data stays yours.
1. Overview & Our Commitment
CalcHub operates on a strict privacy-first principle. Because our tools are built as frontend-only web applications, we do not require user accounts, sign-ups, or login credentials. You can use all 51 calculators freely with complete anonymity.
2. 100% Client-Side Computation
When you enter your financial figures—such as bank balances, asset valuations, business revenues, salaries, or expense breakdowns—into any CalcHub calculator, all computations occur locally inside your web browser using JavaScript.
Your numbers are never transmitted, uploaded, logged, or stored on any external server or database. Once you close your browser tab, your calculation data is instantly cleared from memory.
3. Cookies & Tracking Technologies
We do not use tracking cookies, advertising remarketing pixels, or third-party behavioral analytics scripts. We respect your browsing privacy and do not track or profile your activity across the web.
4. External Links
CalcHub may contain links to external educational resources or partner sites. We are not responsible for the privacy practices or content of external websites. We encourage you to review the privacy policies of any external sites you visit.
5. Policy Updates
We may update this Privacy Policy from time to time to reflect improvements in our web architecture or legal compliance. Any updates will be posted directly on this page with a revised effective date.
