Overview
BMI — Weight & Progress Tracker (the “App”) helps you track body progress. This policy explains what information the App handles, where it is stored, and when information may be processed by Apple or third-party services used to operate subscriptions and paywalls.
Data stored on your device
The App may store your height, weight history, BMI-derived information, goals, body measurements, notes, reminder settings, and progress photos. This information is used to provide the App’s tracking features.
Progress photos are stored in protected local app storage and are not uploaded to an App-operated server. The App has no user-account system or product backend for your sensitive body-progress data.
Apple Health
Apple Health integration is optional. If you enable it, the App requests access only to body mass. The App can import body-mass samples and, if you separately allow it, write new weight entries to Apple Health. The App remains usable without HealthKit.
Subscriptions and paywalls
Purchases are made through Apple’s App Store infrastructure. The App uses RevenueCat for subscription entitlement and purchase metadata, and Superwall for paywall presentation and interaction metadata. The App’s current privacy disclosures identify device identifiers, product interaction, and purchase history for analytics and/or app functionality, with those data categories described as not linked to you.
Your exact weight, BMI, measurements, notes, goals, and progress photos are not intentionally sent to RevenueCat or Superwall.
Analytics and advertising
The App does not use a general-purpose third-party analytics SDK or third-party advertising SDK for your sensitive body-progress data.
The App contains an optional Apple Ads attribution integration that is disabled by default. If enabled for an Apple Ads campaign, the App obtains a short-lived attribution token from Apple’s AdServices framework and sends it directly to Apple’s attribution endpoint. Apple’s returned campaign attribution metadata may be cached locally. The raw token is not intentionally persisted or logged, and this feature does not use the device advertising identifier.
Notifications
If you enable weigh-in reminders, the App schedules local notifications on your device. Reminder content does not include your weight or BMI values.
Data sharing
BMI does not intentionally sell your sensitive body-progress data. Information may be handled by Apple and the subscription/paywall services described above when those features are used, subject to their own terms and privacy practices.
Changes to this policy
If the App’s data practices materially change, this policy should be updated to reflect those changes.

Important health note.BMI is a screening and progress-tracking tool, not a medical service.
1. About the App
BMI — Weight & Progress Tracker provides BMI screening information and body-progress tracking for general informational purposes.
2. Not medical advice
BMI is a general screening measure and does not account for factors such as muscle mass, body composition, age, or individual health circumstances. The App does not provide medical advice, diagnosis, or treatment. Do not rely on the App as a substitute for advice from a qualified healthcare professional.
3. Premium subscriptions
Premium access may be offered through auto-renewable subscriptions purchased through Apple. Pricing, trial eligibility, renewal period, and billing terms are shown using live App Store product information at the time of purchase. Apple’s billing and StoreKit records are authoritative for your transaction.
If a seven-day free trial is offered for an annual subscription, eligibility is determined through Apple’s systems. You can manage or cancel subscriptions through your Apple account subscription settings.
4. Your use of progress features
You are responsible for deciding whether and how to use weight history, BMI information, body measurements, reminders, progress photos, and Apple Health integration. You should enter and interpret information with appropriate care.
5. Apple Health
Apple Health integration is optional. If enabled, access is limited to body-mass data as described in the App’s privacy policy and the permissions you grant through iOS.
6. Availability and changes
Features may be improved, changed, suspended, or removed as the App evolves. Subscription features are also subject to Apple’s App Store services and the availability of third-party subscription and paywall infrastructure.
7. Disclaimer
To the extent permitted by applicable law, the App is provided on an “as is” and “as available” basis. No guarantee is made that BMI calculations, trends, reminders, or other information will be error-free or appropriate for every individual circumstance.
