Privacy Policy

Last updated: October 12, 2025

We designed AtlasCalc to answer questions without demanding personal information. The calculators, converters, and planners that appear on this site run locally in your browser. Inputs such as loan amounts or body measurements are never sent to our servers. When you opt to store preferences—for example, a default country code or your most recently used tool—we write those values to the browser’s localStorage so they remain under your control and can be cleared at any time.

Cookies and analytics

We use Google Analytics 4 to understand which tools are most helpful and where users may experience friction. Analytics scripts load asynchronously only after you provide consent through the banner presented on your first visit. The data we collect is aggregated, does not include calculator inputs, and automatically expires after fourteen months. You may opt out at any time by disabling analytics within the banner, by adjusting your Google privacy settings, or by installing a browser add-on that blocks GA tracking.

Advertising and third-party scripts

When advertising is enabled, we serve Google AdSense placements in clearly labeled areas outside of interactive content. AdSense may set additional cookies to support measurement and frequency capping. We do not run any other third-party trackers, social widgets, or pixel beacons. If you do not wish to see personalized ads, you can update your preferences through Google’s Ad Settings or disable interest-based advertising in your browser.

Data retention and security

AtlasCalc keeps infrastructure light by deploying static assets and serverless functions on Firebase Hosting’s global platform. We log basic request metadata for seven days to monitor uptime and guard against abuse. No calculator inputs, profile data, or payment records (we do not process payments) are persisted on our servers. If you email us, your message is stored in our shared support inbox hosted by Google Workspace and retained for audit and product planning purposes unless you ask us to remove it.

Your choices and contact

You may request deletion of support emails, ask for confirmation about data retention, or share compliance questions at any time. Write to privacy@atlascalc.com or use the form on our Contact page. We will respond within one business day and confirm once your request has been fulfilled.
