Gravity Defying Fitness Mobile App Policy
This policy applies specifically to the Gravity Defying Fitness mobile application, developed and operated by Gravity Defying Fitness (also operating as GDF Athletic Club).
Our mobile application collects user-provided data (e.g. registration profile, physical body metrics, training schedules, and meal logs) to deliver and customize your training programs and coaching experience.
Location & GPS Data (Run Hub)
When you use the GDF Run Hub feature, the Gravity Defying Fitness mobile application requests access to your device's precise location (GPS) to track your running route, distance, pace, and split times. Location data is processed exclusively during active workout sessions for your personal fitness tracking and is never sold, shared with third parties, or used for advertising.
Microphone Access & Audio Processing
The mobile application requests optional access to your device's microphone to enable voice-based meal logging. When using dictation, speech is converted into text locally or securely via API. Raw audio is never recorded, stored, or sold. The transcribed text is used solely to assist with nutritional calculations.
Health & Fitness Data (Apple Health and Health Connect)
If you choose to connect Apple Health (iPhone) or Health Connect (Android), the Gravity Defying Fitness mobile application reads certain health and fitness data from it. Connecting is optional, and you can disconnect at any time in the app.
What we read: running and walking workouts you recorded with another app or device (such as a watch), including distance, duration, pace and active calories; the route of those workouts, where available; average heart rate during those workouts; and your daily step count. We do not read workouts that were entered by hand. We never write any data back to Apple Health or Health Connect.
How we use it: to add your runs to your GDF history and to count your daily steps in the app. For GDF challenges and events, imported runs are held for review by GDF staff before they count toward any leaderboard or standings. This data is never sold, never used for advertising, never shared with advertisers or data brokers, and never sent to OpenAI.
Where it is stored: imported workouts, routes, heart rate and step counts are stored securely with our provider, Supabase, and are linked to your account. GDF staff can view imported runs when reviewing them for challenges and events.
Motion & Step Data
If you enable daily step counting, the app uses your phone's motion sensor (pedometer) to count steps. On Android this requires the Activity Recognition permission, and on iPhone the Motion & Fitness permission. Step counts are stored with your account and used only for your in-app step totals and challenges. They are never sold or used for advertising.
Data Retention
We keep your data only for as long as we need it to provide the app and meet our legal obligations:
- While your account is open: we keep your profile, body metrics, training plans, workout and run history (including GPS routes), imported health data, step counts, meal logs, photos and posts so the app can show your history and progress. You can remove individual items, such as posts and photos, at any time in the app.
- When you delete your account: your login, profile and all data linked to it are permanently deleted from our live database straight away. This includes workout and run history, GPS routes, imported health data, step counts, body metrics, meal logs, and the photos and posts you uploaded.
- Backups: deleted data may remain in our provider's encrypted backups for up to 30 days, after which it is overwritten. Backups are used only to recover from a system failure.
- Purchase and billing records: records of payments and subscriptions are kept for as long as tax and accounting law requires, up to 7 years. When you delete your account, these records are separated from your account so they no longer identify you.
- Coaching records: notes our staff wrote in their own records may be kept after your account is deleted, with your name and personal details removed.
- Meal descriptions sent to OpenAI: OpenAI does not use them to train its models and may keep them for up to 30 days for abuse monitoring before deleting them.
Account Deletion
We respect your right to manage and delete your personal data:
- You can delete your account at any time directly inside the Gravity Defying Fitness app by navigating to Settings > Delete Account.
- You may also request permanent account deletion, or ask us to remove specific data such as imported health data, by emailing us at gdfathletic@gmail.com. We will complete your request within 30 days.
- You can stop sharing health and step data at any time by disconnecting in the app or changing permissions in Apple Health, Health Connect or your phone's settings. Data already imported stays with your account until you delete it or your account.
Third-Party Data Processors
The application works with trusted service providers to ensure secure storage and operations:
- Supabase: Provides enterprise-grade encrypted authentication, database storage, and secure cloud backups.
- OpenAI: Used solely for calculating meal nutrition estimates from user-provided descriptions. No personal identity data is shared.
