FitBridge Gym · effective 12 September 2026
FitBridge Gym is built so that your training data stays yours. This page explains what the app stores, where, and why.
What the app collects
- Workouts you log: exercises, sets, weights, reps, treadmill entries, notes, and coach notes generated on your device.
- Health data you allow from Apple Health: steps, distance, energy, heart rate, resting heart rate, heart-rate variability, VO₂ max, respiratory rate, sleep, blood oxygen, weight, body fat and workouts. The app writes back heart rate, steps, weight, body fat and workouts. Health data is never sold or used for advertising.
- Heart rate from a Bluetooth band while connected.
- Body logs and diet plans you enter or import.
- Account: your email address and a user ID, if you create an account.
- Challenge data you choose to share: display name, an optional cut-out photo, scores, posts and photos on a challenge wall.
- Location, only if you set a gym: the app records when you enter and leave a circle around it. Coordinates stay on your phone; only visit start and end times are stored.
Where it is stored
Everything is stored on your iPhone. If you sign in, your data is synced to your own space in Google Firebase (Firestore), protected by rules that let only your account read or write it, except challenge data, which members of that challenge can read. Heart-rate readings, steps and gym visits expire in the cloud after the retention period you choose (30, 90 or 365 days).
On-device intelligence
Coach notes, the coach chat, the weekly narrative, diet import and challenge suggestions use Apple's on-device model. Text and photos processed this way do not leave your phone.
Meal photos (from version 1.1)
If you choose to photograph a meal for a calorie estimate, that photo is sent over an encrypted connection to FitBridge's analysis service, which forwards it to Google's Gemini model to name the food and estimate portions. The photo is processed and discarded; it is not stored by FitBridge, and only a small thumbnail you can delete stays on your phone. The feature is optional, asks for your consent before the first photo, and is limited to 10 photos a day. Barcodes are looked up on Open Food Facts, a public database, without any account information. Your food log itself stays on your iPhone and, if you allow it, in Apple Health.
Challenge walls
Posts and photos on a challenge or squad wall are end-to-end encrypted. The key is created on the creator's phone and shared only inside invite links; FitBridge's servers store ciphertext and cannot read a wall.
What we do not do
- No advertising, no trackers, no analytics SDKs. We never sell your data, and we never share it for advertising or profiling. The one third party that ever receives your content is Google, when you choose to send a meal photo for analysis, as described above — and Google processes it to return the estimate, does not use it to train its models, and does not receive your name, account or any other health data. Google's handling of that request is covered by the Google APIs Terms of Service and Google's Privacy Policy, which provide protections equivalent to those described here.
- No location data is uploaded.
Your choices
