Privacy Policy for Peptide Tracker
Short version: Peptide Tracker is a personal tracking and education app. We use the data you enter to provide dose logs, body logs, schedules, reminders, exports, and subscription access. We do not sell your personal data. Health Connect and Apple Health access is optional and controlled by you.
This Privacy Policy explains how Peptide Tracker Calculator App ("Peptide Tracker", "we", "us", or "our") collects, uses, stores, and protects information when you use our mobile application. The app is intended for personal record-keeping, research, and educational purposes only. It does not provide medical advice, diagnosis, or treatment.
Information We Collect
Account information
When you sign in, we collect account information provided through the authentication provider you choose, such as your user identifier and email address. On Android, the app supports Google Sign-In through Supabase Auth. On iOS, the app supports Apple Sign-In through Supabase Auth.
Information you enter in the app
The app lets you create and manage personal tracking records. Depending on how you use the app, this may include:
- Peptide names, custom peptide settings, units, half-life estimates, peak-time estimates, interval settings, inventory details, and notes.
- Dose logs, amounts, units, routes, injection sites, notes, timestamps, and schedule information.
- Observation and symptom logs, including type, label, category, severity, notes, related peptide name, and timestamps.
- Body logs, including weight, body fat, waist, hip, chest, abdomen, neck, arm, thigh, resting heart rate, blood pressure, units, notes, and timestamps.
- Feedback, feature requests, ratings, and related message text that you choose to send.
- Legal disclaimer acceptance records, including the disclaimer version, acceptance time, source, account identifier, and email address.
Subscription information
If you purchase or restore a subscription, RevenueCat processes subscription events and sends subscription status to our backend so the app can unlock paid features. We store your app user identifier, subscription plan, and update time. Payment details are handled by the applicable app store and RevenueCat; we do not receive your full payment card information.
Notifications and device settings
If you enable reminders, the app stores notification preferences and schedule information so local device notifications can be scheduled. You can disable reminders in the app or through your device settings.
Health Connect and Apple Health Data
Health data access is optional. The app asks for health permissions only when you choose to connect Health Connect on Android or Apple Health on iOS. You can deny, limit, or revoke these permissions at any time in your device health settings.
Health data we may read
If you grant permission, Peptide Tracker may read selected wellness data to show context next to your personal tracking records. This may include:
- Steps and step trends.
- Sleep sessions, sleep duration, and sleep stages.
- Exercise or workout sessions and workout duration.
- Resting heart rate and heart rate variability.
- Active calories burned, exercise minutes, VO2 max, and heart rate recovery where available.
- Respiratory rate.
- Weight, body fat percentage, and lean body mass.
Health data we may write
If you explicitly choose to share a body log to Health Connect or Apple Health, Peptide Tracker may write eligible values you entered, such as weight, body fat percentage, resting heart rate, and blood pressure. Sharing is optional and occurs only when you turn on the sharing option for that entry or use a health-sharing action.
How health data is used
Health data is used to display wellness context, charts, trends, and exports inside the app, and to write eligible values back to Health Connect or Apple Health only when you choose to do so. We do not use Health Connect or Apple Health data for advertising, credit decisions, employment decisions, insurance eligibility, or sale to data brokers.
How health data is stored
Health metrics read directly from Health Connect or Apple Health are stored on your device for app display and syncing status. Manually entered body logs are saved in your Peptide Tracker account and may be stored in Supabase so you can access them across devices. These body logs can include health-related values that you typed into the app.
Your access and deletion controls for health data
- You can view, edit, export, or delete your body logs and other tracking entries in the app.
- You can revoke Health Connect permissions in Android Health Connect settings.
- You can revoke Apple Health permissions in iOS Health settings.
- You can delete your Peptide Tracker account in the app under Settings, Data & Account, Delete account.
- You can request access, correction, export, or deletion by contacting us at e.ahmadi95@protonmail.com.
