This Privacy Policy describes how we ("we", "our", or "us") collect, use, and protect your personal data when you use our workout tracking mobile application (the "App") available on Android and iOS platforms. By using the App, you agree to the practices described below.
1. Who We Are
We develop a mobile application to help you track workouts and monitor fitness progress. The App is intended for personal, non-medical use only.
2. What Data We Collect
- Account Data: Your Apple ID or Google Account ID and email address (via secure OAuth sign-in). We do not store passwords.
- Workout Data: Exercises, sets, reps, weights, durations, notes. Synced and stored securely via Firebase.
- Usage Data: App session durations, features used, device type. Tracked via Firebase Analytics.
- Crash Data: App errors, device type, app version. Collected via Firebase Crashlytics.
- Purchase Metadata: Subscription status, plan details via RevenueCat. No financial data is collected or stored by us.
- Health Data (optional): If you choose to connect Health Connect (Android) or Apple Health (iOS), the App reads your steps, active calories burned, body weight and body fat percentage, and writes your body weight, body fat percentage, completed workouts and an estimated calorie count for each workout. This is off until you connect it, and you choose which data types to allow. See section 4 for details.
- Watch Apps (iOS & Android): If using our watch applications, we read your heart rate from the watch strictly for read-only purposes. We do not store, transmit, or do anything else with this data.
3. How We Use Your Data
- Authenticate your account and sync your workout logs
- Show and sync the health data you choose to connect, and save your workouts and measurements to your health app (see section 4)
- Improve and debug app features
- Monitor usage trends to enhance the user experience
- Manage subscriptions and purchases
- Respond to customer support inquiries
4. Health Data (Health Connect and Apple Health)
Connecting Health Connect on Android or Apple Health on iOS is entirely optional. The App only asks for access when you tap Connect, and you can allow or decline each data type separately.
- What we read: your steps, active calories burned (the calories your body burned through the day, as shown by your health app), body weight and body fat percentage.
- What we write: body weight and body fat percentage you log in the App, your completed workouts (as strength training sessions) and an estimated calorie count for each workout. The estimate is calculated from your workout time and your body weight around that date. It is an approximation and not medical advice.
- Why: to show your steps, calories and body measurements in the App, to keep your weight and body fat in sync between the App and your other health apps, and to save your workouts to your health app. Imported values are stored in your Gymbro account so they can be restored if you sign in on a new device.
- Your control: you can turn the connection off at any time in the App (Settings > Health Connect or Apple Health) and revoke access in Health Connect or in your iPhone's Health settings. Turning it off stops all syncing. Records the App already saved to your health app remain there, under your control, and can be deleted in that app.
- Limited use: we use this data only to provide and improve these features for you. We do not sell it, and we do not use it for advertising, marketing or interest-based ads. We do not share it with third parties, except with the service providers that store it on our behalf (such as Firebase) or where required by law. Our use of information received from Health Connect and HealthKit follows the policies of Google Play and Apple for health data, including their limited-use requirements.
- Deletion: health data imported into the App is deleted when you delete your account.
5. Data Storage & Security
- All data is stored in secure, cloud-hosted databases using Google Firebase infrastructure
- We implement industry-standard security practices including data encryption at rest and in transit
- Despite our best efforts, no system is completely secure. Use at your own discretion.
6. Data Retention
- We retain your data as long as your account is active. Upon account deletion:
- Workout and personal data, including health data imported into the App, is deleted immediately
- Purchase metadata may be retained as required by platform or financial regulations
- Records the App wrote to Health Connect or Apple Health stay in that app, under your control, until you delete them there
7. Your Privacy Rights
- Depending on your location (e.g., EU, California), you may have the right to:
- Access and review the data we hold about you
- Correct any inaccurate personal information
- Delete your data permanently
- Export your workout data (e.g., CSV format)
- Withdraw consent for analytics, health data access or third-party integrations (in the App's Settings or your phone's Health settings)
- Contact us at support@gymbro.com to exercise these rights.
