Big Freight Life LLC (“we”, “us”), the developer of Bio Break, is committed to protecting your privacy. Bio Break is designed to be private by default — there are no ads and we do not use third-party analytics or behavioral tracking. Free features store data locally on your device. Pro subscribers' data syncs automatically to our secure cloud backend. AI features are optional, off until you turn them on, and use summaries of your data rather than the entries themselves.

3. AI-Powered Features (Pro Only)
AI features are off until you turn them on. They need a separate permission, asked for on its own and switched off by default. You can use Bio Break, including Pro, with it off, and turn it off at any time in Settings > Data & Privacy. While it is off, nothing is sent to an AI provider, including by our servers.
What AI Does
- Pattern Detection: Looks across your recent days for trends worth pointing out
- Report Summaries: Writes a short summary section for the doctor report
- Photo Scan: Suggests a Bristol type from a photo you take. The suggestion is only recorded if you accept it
- Proactive Nudges: A scheduled job on our servers reviews your recent synced data every few hours and may send a wellness reminder. A structured decision model first judges whether a reminder is worth sending at all
What Is Sent
- Summaries of your entries: each day's counts and averages, and the names of the medications, symptoms and food categories you logged that day
- Never your notes, and never the individual entries themselves
- Never data read from Apple Health
- For Photo Scan only: the photo you take. It is classified and discarded, is not stored by us or by the provider, and never appears in your journal, backups or reports. You are told this before the camera opens
- The app's display language, so that results come back in it
How AI Processes Your Data
- Our backend sends each request to OpenRouter, which routes it to an AI model provider
- Every request is restricted to providers that do not retain the data or use it to train models. If no such provider is available, the request fails rather than falling back to one that does
- Decisions such as whether a reminder is worth sending are made by a structured decision model (TypeSafe's Jev) reached through the same provider. It receives the same summaries and returns a probability rather than text
- AI responses are for informational purposes only and do not constitute medical advice
AI Limitations
- AI features will never diagnose medical conditions
- AI responses are general guidance, not medical advice
- Always consult a healthcare professional for medical concerns
5. Data Storage & Security
On-Device Storage
- Local by default: All health data is stored on your device using iOS Data Protection (NSFileProtectionComplete)
- Keychain: Authentication credentials stored with kSecAttrAccessibleWhenUnlockedThisDeviceOnly
Cloud Sync (Pro)
- Convex backend: If you sign in and have Pro, entries upload automatically as you save them, including any notes you write. Data is encrypted in transit (TLS) and at rest
- iCloud (CloudKit): Data also syncs through your private iCloud database. This is on by default and is covered by Apple's encryption terms, including Advanced Data Protection if you have enabled it on your Apple Account
HealthKit Data
- Heart rate, blood pressure, sleep and menstrual flow read from HealthKit are used locally and never transmitted off-device
- HealthKit data is not stored in iCloud or synced to any backend
Privacy Manifest
- NSPrivacyTracking: false — we do not track users
- Tracking domains: None
6. Data Retention
On-Device Data
- Data is retained on your device for as long as you use the app
- Uninstalling the app removes all local data
Cloud Data (Pro)
- Account data is retained while your account is active
- You can delete your account and all server-side data through the app's Account settings
- Account deletion permanently removes all data from our servers
- If you cancel Pro, it stays available until the end of the period you have paid for. After that the app returns to the free tier: your journal stays on your device, and sync and AI features stop
- Push tokens from devices not used for 30 days are deleted
AI Data
- Summaries and photos sent for AI processing are processed transiently and not retained by the provider or used for training
- Photos taken for Photo Scan are not stored by us at any point
7. Cookies & Tracking
What We Don't Do
- No cookies
- No third-party behavioral analytics (we use Firebase Crashlytics for crash reporting only, not behavioral analytics)

9. International Data Transfers
- Local storage: Health data is stored on your device and does not leave your device unless you use Pro features
- iCloud sync: If enabled, data is transferred and stored by Apple under their privacy terms
- Cloud backend: If you use Pro features, your data may be transferred to Convex servers, and, if you turn AI on, to OpenRouter and the model providers it routes to, which may be located outside your country
