Privacy Policy

Last updated: August 28, 2026

1. Zero Data Collection Philosophy

At Calculators Hub, we believe your data is yours. We have engineered our platform so that we simply cannot see the numbers you crunch. We do not collect, transmit, store, or sell any information you enter into our calculators.

2. Client-Side Execution

All computational logic occurs client-side. This means the math is done right in your web browser. When you calculate a mortgage or evaluate a health metric, the inputs and outputs never touch our servers.

3. Local Storage

We may use local storage in your browser to save your preferences (such as theme choice or recent calculations) solely to enhance your user experience. This data remains on your device and is never uploaded to our servers.

4. Third-Party Services

We may use anonymous, aggregated analytics services (like standard web traffic counters) to understand overall site usage and performance. These tools do not capture individual calculator inputs.

5. Contact Us
