Privacy Matters.
At HQCalc, we believe your data belongs to you. This policy outlines how we protect your information while you use our 120+ tools.
No Server-Side Storage
All calculations are performed locally on your device. We do not store your financial, health, or personal inputs on our servers.
Zero Tracking
We do not sell your data to third-party advertisers. Your privacy is our priority, not our product.
Browser-Level Encryption
Any data used for temporary sessions is encrypted within your browser and cleared as soon as you close the tab.
1. Data Collection
HQCalc does not require users to create an account or provide personal identification (PII) to use our basic calculators. We may collect non-identifiable technical data such as browser type and session duration via standard analytics to improve site performance.
2. Calculation Privacy
Whether you are calculating your Income Tax or BMI, the logic is executed using JavaScript in your browser. This means your numbers are never transmitted over the internet to our backend.
3. Cookies & Ads
We use Google AdSense to monetize our free tools. These third-party vendors may use cookies to serve ads based on your prior visits. You can opt-out of personalized advertising by visiting Google's Ads Settings.
Policy Updates
This policy was last updated on April 16, 2026. We reserve the right to update our privacy practices as we add more complex features to HQCalc.
