Privacy Policy

1. Introduction

Macro Maxxing (“we”, “our”, or “us”) operates the Macro Maxxing mobile application (the “App”). This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

2. Information We Collect

2.1 Information You Provide

• Account information: email address, display name, and profile photo (optional).
• Nutrition data: food logs, macro entries, meal photos, and daily nutrition totals (calories, protein, carbs, fat).
• Fasting data: fasting timer start/end timestamps and fasting window preferences.
• Body metrics: weight, body measurements, and fitness goals (if provided).
• Voice input: audio recordings when using voice food logging (processed in real-time, not stored).

2.2 Information Collected Automatically

• Device type, operating system version, and app version.
• Anonymous usage analytics (screens viewed, features used).
• Crash reports and performance diagnostics.

2.3 Information from Food Photos

When you use the AI food scanner, your photo is sent to our servers for analysis. Photos are processed to estimate nutritional content and are not retained after analysis is complete unless you choose to save them to your food log.

3. How We Use Your Information

• To provide and improve the App's features.
• To analyze food photos and estimate macro/calorie content.
• To display your nutrition history, streaks, and leaderboard rankings.
• To send you notifications (e.g., fasting reminders, streak alerts) if you opt in.
• To diagnose bugs and improve app performance.

4. Third-Party Services

We use the following third-party services to operate the App. Each has its own privacy policy governing how it handles data:

• Firebase (Google): Authentication, cloud database, analytics, and crash reporting. Data may be stored on Google servers in the United States. Firebase Privacy Policy
• Anthropic (Claude AI): All AI food photo analysis and voice input processing is handled exclusively by Anthropic's Claude models (Haiku and Sonnet). Photos and text are sent to Anthropic's API for analysis. No other third-party AI services are used. Anthropic Privacy Policy
• USDA FoodData Central: Nutritional database lookups for food items. Only food search queries are sent; no personal data is transmitted. USDA API Info
• Google AdMob: In-app advertising, including banner, interstitial, and rewarded ads. AdMob may collect device identifiers (such as the Advertising ID), IP address, and interaction data to serve and measure ads. Ad data is processed by Google. Google Ads Privacy

5. Data Sharing

We do not sell your personal information to third parties. We share data only in the following circumstances:

• With the third-party services listed above, solely to provide App functionality.
• With other users, if you participate in social features (leaderboards, community posts). You control what you share publicly.
• If required by law, regulation, or valid legal process.

6. Data Retention

We retain your account and nutrition data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where we are required to retain it for legal or compliance purposes. Anonymous, aggregated analytics data may be retained indefinitely.

7. Your Rights

You have the right to:

• Access your data — view all nutrition logs, fasting history, and account information within the App.
• Export your data — export a full copy of your data in JSON format directly from Account > Privacy & Data > Export My Data in the App.
• Delete your data — delete your account and all associated data from within the App settings or by contacting us.
• Correct your data — edit or update any information you have provided.
• Opt out of notifications at any time through your device settings.

8. Data Security

We use industry-standard security measures to protect your data, including encryption in transit (TLS) and at rest. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.

9. Children's Privacy

The App is not intended for children under 13. We do not knowingly collect personal information from children under 13. If we learn that we have collected data from a child under 13, we will delete it promptly.

10. Advertising & Cookies

The App itself does not use cookies. Our website (macromaxxing.app) may use cookies and similar tracking technologies for analytics and to improve your browsing experience.

We display advertisements within the App using Google AdMob, including banner ads, interstitial ads, and rewarded ads. Google AdMob may collect device identifiers (such as your Advertising ID), IP address, and ad interaction data to serve and measure personalized ads. You can opt out of personalized advertising by adjusting your device settings:

• iOS: Settings > Privacy & Security > Tracking, and disable “Allow Apps to Request to Track.”
• Web: Manage cookie preferences via your browser settings or our cookie banner (if displayed).

11. International Data Transfers

Your data may be processed and stored on servers located in the United States and other countries where our service providers operate (including Google and Anthropic). By using the App, you consent to the transfer of your information to countries that may have different data-protection laws than your country of residence. We take steps to ensure that your data receives an adequate level of protection wherever it is processed.

12. Your Privacy Rights Under Applicable Law
