Privacy Policy

Last updated: May 2026

Mackro ("the App") is built to respect your privacy. This policy explains what data the App uses and how.

Data Stored on Your Device

All food logs, custom foods, macro goals, and settings are stored locally on your device using Apple's SwiftData framework. If you have iCloud enabled, this data syncs across your devices via CloudKit — encrypted in transit and at rest, managed entirely by Apple.

Apple HealthKit

With your permission, the App can write nutrition data (calories, protein, carbohydrates, fat) to Apple Health. This data is stored in the Health app and governed by Apple's privacy policies. The App does not read from HealthKit.

AI Photo Logging

When you use the AI photo logging feature, photos you choose are sent to Anthropic's Claude API for meal analysis. The following applies:

Photos are sent only when you explicitly tap "Analyze Photo"
Images are not stored or used for model training by Anthropic
Anthropic's data handling is governed by their privacy policy
This feature is capped at 10 uses per day

Analytics & Advertising

The App contains no third-party analytics, no advertising SDKs, and no crash reporting services. No behavioral data is collected or sold.

Notifications

If you enable meal reminders, the App uses iOS local notifications. These are processed entirely on-device and no notification data leaves your device.

Data Deletion

All app data can be deleted by removing the App from your device. To delete iCloud-synced data, go to Settings → [Your Name] → iCloud → Manage Storage.
