Privacy Policy

This Privacy Policy describes how MacroEngine ("we," "us," or "our") collects, uses, stores, and discloses information when you use our website at macroengine.app (the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1a. Information You Enter Into Our Tools

When you use our calculators and trackers, you may enter personal data including your biological sex, age, body weight, height, and activity level. This data is processed entirely within your browser using client-side JavaScript and is never transmitted to our servers. It exists only in your browser's local memory and, where the tool uses persistence features (such as the Fasting Timer and Water Tracker), in your browser's localStorage on your own device.

You can delete this locally stored data at any time by clearing your browser's site data for macroengine.app through your browser settings.

1b. Contact Form Submissions

If you submit a message through our Contact page, we collect the information you provide, which may include your name, email address, and the content of your message. This information is used solely to respond to your inquiry. We do not add contact form submitters to marketing lists without explicit opt-in consent.

1c. Automatically Collected Data

Like most websites, our server may automatically collect certain technical data when you visit, including your IP address, browser type and version, operating system, referring URL, and pages visited. This information is collected in standard server access logs and is used for security monitoring, performance analysis, and troubleshooting purposes. We retain server logs for a maximum of 90 days.

2. Cookies and Tracking Technologies

MacroEngine uses minimal cookies necessary for the operation of the Service. We do not use third-party behavioral tracking cookies without your consent. If Google AdSense advertising units are displayed on this site, Google may set cookies in accordance with its own privacy policy (available at policies.google.com/privacy). You can opt out of personalized Google advertising at adssettings.google.com.

You can control cookie settings through your browser preferences. Disabling cookies may affect the functionality of certain features on this site, including the ability of certain widgets to remember your preferences.

3. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the Service and its features.
• Respond to your questions, comments, and support requests.
• Monitor and analyze usage patterns to improve user experience.
• Detect, investigate, and prevent fraudulent or unauthorized activity.
• Comply with applicable legal obligations.

We do not sell, rent, or trade your personal information to third parties for their marketing purposes.

4. Data Storage and Security

As noted above, the health and body composition data you enter into MacroEngine's calculators is stored only on your device via localStorage and is never transmitted to our servers. Contact form data is transmitted over HTTPS encryption and stored securely.

We implement reasonable technical and organizational security measures to protect information under our control against unauthorized access, disclosure, or destruction. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security.
