Your privacy is of paramount importance to us at HyperCalc.net. This Privacy Policy details our practices concerning data collection, storage, and processing.
1. Local In-Browser Processing Guarantee
All calculation inputs—including loan principals, interest rates, personal body weights, heights, birthdates, and income figures—are processed purely locally within your browser using JavaScript. No calculation values are ever uploaded to, transmitted to, or stored on our servers.
2. Cookies & Local Storage
HyperCalc.net uses lightweight localStorage solely to remember your UI display preference (Light Mode vs. Dark Mode). We do not deploy invasive third-party cross-site advertising tracking pixels.
3. Third-Party Hosting & Server Logs
Like all web platforms, when you request a page on HyperCalc.net, standard non-personally identifiable web server access logs (such as IP address, browser user-agent, and requested file) may be temporarily recorded by content delivery network (CDN) edge servers to detect security threats and prevent DDoS attacks.
4. Updates to this Policy
We may periodically update this policy to reflect enhancements in our architecture. Changes take effect immediately upon posting.
