MacroCut Privacy Policy

Last updated: September 15, 2026

MacroCut ("the app", "we", "our") is developed by StackVigil ("the developer"). This policy explains what information MacroCut handles and how.

Summary

Information the app uses

To build your nutrition and fitness plan, MacroCut asks you for:

• Basic profile details: name, age, sex, height, weight, activity level, and goal
• Diet preference and any foods you want to exclude
• Optional VO₂ max fitness goals and cardio preferences, and strength training days per week
• Meal completion, meal swaps, and weight entries you log over time
• Strength training sets, reps, and weight you log against your workouts
• Blood glucose readings and HbA1c lab results you enter manually
• Optional photos you attach to meals

If you choose to connect Apple Health, MacroCut reads (never writes):

• Body weight
• VO₂ max / Cardio Fitness
• Step count
• Active energy burned
• Workouts
• Blood glucose

All of this information is stored only in local storage on your device (UserDefaults) or, for meal photos, in your device's local app storage. None of it is transmitted to any server, because MacroCut doesn't have one. We — the developer — never see any of your data, including your blood glucose readings or HbA1c results.

Apple Health

MacroCut requests read-only access to Apple Health data solely to personalize your nutrition plan, aerobic fitness roadmap, and glucose tracking, and to let you sync your logged weight, VO₂ max, and blood glucose automatically. In accordance with Apple's guidelines:

• MacroCut does not write any data back to Apple Health, except the read-only sync described above.
• Health data read from Apple Health is never used for advertising, marketing, or any purpose unrelated to the features described in the app.
• Health data is never sold, rented, or disclosed to any third party, including data brokers or resellers.
• Health data is never shared with third-party analytics or advertising services, because MacroCut does not include any.
• Blood glucose data is treated the same as every other Health data type MacroCut reads: read-only, on-device only, never transmitted anywhere.

Subscriptions and purchases

MacroCut offers an optional premium subscription (strength training plans with exercise form guides, the VO₂/cardio roadmap, glucose trend charts, and adaptive coaching) through Apple's App Store In-App Purchase system.

• All payment is processed entirely by Apple. MacroCut never receives, sees, or stores your payment card details, billing address, or any other payment information.
• MacroCut checks your subscription status on-device using Apple's StoreKit framework, purely to determine which features to display. This check does not transmit any of your personal or health data to Apple or to us.
• To manage, change, or cancel your subscription, use your Apple ID subscription settings — MacroCut has no ability to modify your subscription directly.

Data retention and deletion

Because everything is stored locally, you are always in control:

• Deleting the app deletes all of its data from your device.
• Using "Run onboarding again" in Profile settings clears your profile, meal history, plan adjustments, VO₂ plan, cardio history, strength training logs, glucose readings, HbA1c results, and reminders (your logged weight history is kept unless you also delete the app).
• MacroCut cannot delete data on our behalf because we never have a copy of it.

Notifications

If you enable meal reminders, MacroCut schedules local notifications on your device using iOS's built-in notification system. These notifications are generated and delivered entirely on-device; no reminder content is sent to or through any server.

Children's privacy

MacroCut is not directed at children under 13, and we do not knowingly collect information from children, consistent with the fact that the app collects no information at all beyond what is stored locally on the user's own device.

Changes to this policy

If this policy changes, we will update the "Last updated" date above. Continued use of the app after a change constitutes acceptance of the updated policy.

This document is a draft prepared for the developer's review. Have someone familiar with your local privacy/consumer-protection laws review it if you plan to distribute outside your home country — this draft is written to satisfy Apple's App Store requirements, not as legal advice. Given MacroCut now handles blood glucose data specifically, consider having this reviewed by counsel familiar with health-data regulations in the regions you plan to distribute in (e.g., HIPAA does not apply here since MacroCut is not a covered entity/business associate, but other regional health-data rules may still be relevant).
