Cal 30
Privacy Policy

Your Privacy, Protected

Cal 30 is an AI-powered 30-day calorie and nutrition planner. This policy explains exactly what data we collect, why, and how we protect it.

Cal 30 Health & Nutrition iOS App Last updated: May 9, 2026
🔒

The short version: Cal 30 stores your nutrition and goal data securely in the cloud, uses AI to generate meal plans and scan food photos, and uses Apple Sign In so we never handle your password. We do not sell your data, serve ads, or share your information with advertisers — ever.

1

Account & Authentication

How you sign in and what account data we hold.

Sign In with Apple
Cal 30 uses Apple Sign In exclusively. Apple authenticates your identity and delivers a secure token to our app. We never receive or store your Apple ID password. Apple may provide a private relay email at your discretion — we use this only to associate your account.
Account Deletion
You can permanently delete your account and all associated data from within the app via Settings → Delete Account. Deletion is irreversible and takes effect immediately.

Health & Profile Data

What you share during onboarding and how it's used.

Onboarding Information
During setup you provide: gender, age, current weight, height, goal weight, weight-change speed, diet type (e.g. Balanced, Keto, Vegan), food restrictions, health conditions, activity level, country, and preferred meals per day. This data is used solely to calculate your personalized calorie and macro targets and to generate your 30-day plan.
Progress Tracking
Cal 30 tracks your 30-day cycle progress, including your start weight and target weight for each cycle. This data is stored securely in your account and is visible only to you.
No Apple Health Integration
Cal 30 does not read from or write to Apple Health. Your Apple Health data is never accessed by this app.
Medical Disclaimer
Cal 30 is a nutrition planning tool, not a medical device or service. Calorie and macro recommendations are for informational purposes only and do not constitute medical advice. Always consult a qualified healthcare professional before making significant dietary changes.

Meal Logs & Food Data

Every meal entry you log and how it's stored.

Manual Meal Entries
Meals you add manually — including name, type, portion size, calories, protein, carbs, and fats — are stored securely in your account. Your full meal history is accessible only to you.
AI-Generated Meal Plans
When you request a meal plan, your goals, diet type, restrictions, and calorie targets are sent to our AI service to generate personalized suggestions. The resulting plan is saved to your account.
Food Photo Scanning
When you scan a meal photo, the image is sent to our AI service for nutritional analysis. The image is used only for this single request and is not stored on our servers. The nutritional result is saved to your meal log. Camera and Photo Library access requires your explicit permission.
Barcode Scanning
When you scan a product barcode, only the barcode number is sent to the Open Food Facts public database to retrieve nutritional information for that product. No personal information is included in this request. The result is saved to your meal log.

AI Features

How AI powers meal generation, food scanning, and chat.

What Is Sent to AI
Three features use AI: Meal plan generation (sends your goals and diet preferences — no name or contact info); Food photo scanning (sends the selected image for nutritional estimation — not stored after processing); and AI nutrition chat (sends your messages with basic plan context). No personally identifying information is included in AI requests.
Daily Usage Limits
To protect your account, AI usage is capped per user per day. Limits reset at midnight.

Camera & Photo Library

Optional permissions used only for food scanning.

Food Scanning Only
Camera and Photo Library access is requested only when you choose to scan a meal. Photos are used only for that single analysis and are never stored on our servers or saved back to your photo library.
Revoke Anytime
Both permissions are optional. You can revoke them at any time via iPhone Settings → Cal 30. All other app features continue to work normally.
6

Notifications

Optional daily reminders to log your meals.

Local Notifications Only
All notifications in Cal 30 are scheduled locally on your device. No external messaging service is involved and notification content never leaves your device.
Optional Permission
Notification permission is entirely optional. Declining or revoking it has no impact on any other feature of the app.

Data Storage & Sharing

Where your data lives and who can access it.

Secure Cloud Storage

No Data Selling
We do not sell, rent, or share your personal data with advertisers, data brokers, or any third party beyond the service providers needed to operate the app.
