⚙️ How We Use Your Information
We use the information we collect to:
- Provide, operate, and improve the MunchLog application
- Calculate your personalized daily calorie and macro goals using the Mifflin-St Jeor BMR formula
- Display your nutrition history, weight trends, and water intake progress
- Send you push notifications (only if you've opted in) for meal reminders and goal celebrations
- Process your food descriptions through our AI to estimate calories and macronutrients
- Fix bugs, improve stability, and build new features based on aggregated usage data
We never use your personal health data for advertising purposes, and we never sell it to third parties.
🤖 AI Processing of Food Descriptions
MunchLog's core feature uses AI to estimate nutritional content from your meal descriptions. Here's how it works and what it means for your privacy:
How it works
When you type or say what you ate, your meal description is sent to our AI processing service (powered by Anthropic's Claude API). The AI analyzes the text and returns estimated calorie and macronutrient values. The description is processed to provide the estimate and is not stored by the AI provider beyond the immediate processing window.
What is sent to the AI
- Your plain-text meal description (e.g., "two scrambled eggs and toast")
- Optional: a food photo if you choose to attach one
We do not send your name, weight, age, or other profile data to the AI service.
Important disclaimer: AI-generated calorie and macro estimates are approximations only. They should not be used as the sole basis for medical, dietary, or health decisions. Always consult a qualified healthcare professional or registered dietitian for medical nutrition advice.
💾 Data Storage & Security
Local Storage
All your personal health data — meals, weight logs, water tracking, and profile information — is stored locally on your device using encrypted device storage. This means your data stays on your phone and does not leave it, except when using features that require server communication (such as AI meal analysis).
Security Measures
- All data transmission between the app and our servers uses TLS encryption (HTTPS)
- We do not store your meal descriptions or health data on our servers after processing
- Your device's native security (Face ID, PIN, etc.) protects app data at rest
Data Retention
Your data lives on your device for as long as the app is installed. Deleting the app removes all locally stored data. If you delete a meal entry or weight log within the app, it is permanently removed immediately.
🤝 Sharing Your Information
We do not sell, rent, or trade your personal information. We may share information only in these limited circumstances:
Service Providers
We work with a small number of trusted third-party services to operate MunchLog:
- Anthropic (AI processing): Meal descriptions are sent to Anthropic's Claude API for nutritional analysis. Anthropic's privacy policy governs their use of this data.
- RevenueCat (subscriptions): Handles in-app purchase processing. They receive transaction data but not your health data.
- Crash reporting service: Anonymous, non-identifiable error logs only.
Legal Requirements
We may disclose information if required by law, court order, or government authority, or if we believe disclosure is necessary to protect the rights, property, or safety of MunchLog, our users, or the public.
💳 In-App Purchases
MunchLog offers optional premium features through in-app purchases, processed by Apple App Store and Google Play Store. We do not collect or store your payment card information — all payment processing is handled entirely by Apple and Google.
Purchase history is managed through RevenueCat, which helps us validate your subscription status. RevenueCat receives a unique user identifier and transaction data. See RevenueCat's Privacy Policy for details.
👶 Children's Privacy
MunchLog is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at privacy@munchlog.net and we will take steps to delete that information.
For users between 13 and 18, we recommend parental guidance when using nutrition tracking apps, as health data is sensitive.
⚖️ Your Rights & Choices
Access and Deletion
Since your data is stored locally on your device, you have full control at all times:
- View all your data directly within the app
- Delete individual meal entries, weight logs, or water records at any time
- Delete your entire profile and all associated data by deleting the app
Push Notifications
You can enable or disable push notifications at any time through your device's Settings → Notifications → MunchLog.
California Residents (CCPA)
California residents have the right to know what personal information we collect, the right to delete it, and the right to opt out of the sale of personal information. We do not sell personal information. To exercise your rights, contact us at privacy@munchlog.net.
EU/EEA Residents (GDPR)
If you are located in the EU or EEA, you have rights under the General Data Protection Regulation including the right of access, rectification, erasure, and data portability.

📝 Changes to This Policy
We may update this Privacy Policy from time to time. When we make significant changes, we'll notify you through the app or by updating the "last updated" date at the top of this page. We encourage you to review this policy periodically.
