AtlasCalcs calculators run in your browser: inputs you type stay on your device and are never sent to our servers. This page summarizes the limited data we do process.

Calculator inputs stay on your device
Every calculation runs client-side in JavaScript. Loan amounts, health metrics and other inputs you enter are processed locally and never transmitted to AtlasCalcs servers, sold, or used for advertising profiles. Closing the tab discards them.
What we do collect
Standard privacy-preserving analytics (pages visited, device type, coarse geography) help us find broken tools and prioritize fixes. Analytics vendors process IP addresses to provide that service under their own policies. Contact messages you send via contact are retained to resolve your report. See terms of service for acceptable use and accessibility for assistance options.
