Privacy Policy
This policy explains what BiLT collects, why, and what we do with it. We've tried to write it in plain language. If anything is unclear, email [email protected].
Who we are
BiLT is a fitness tracking app developed by an independent developer ("BiLT," "we," "us"). The app is available on iOS and Android.
What we collect
Account information
When you create an account, we collect your email address (via Google Sign-In or Sign in with Apple) and a display name you choose. We do not collect or store passwords — authentication is handled by Google or Apple.
Fitness and health data you enter
BiLT stores the training, cardio, body, and nutrition data you log in the app. This includes workouts, sets and reps, cardio sessions, body measurements, food entries, photos you choose to attach, and any notes or preferences you set.
Apple Health data (iOS, if you opt in)
If you enable Apple Health integration, BiLT reads the following from Apple HealthKit:
- Workouts (type, duration, start/end time)
- Heart rate samples during your workouts
- Active energy burned
- Walking, running, and cycling distance
- Body weight
- Body fat percentage
This data is used to log cardio sessions and prefill weekly check-ins in your BiLT account. BiLT does not sell HealthKit data, use it for advertising, share it with data brokers, or use it for any purpose other than the features you've requested. You can disable Apple Health integration at any time in BiLT's settings, and you can revoke BiLT's HealthKit permission at any time in iOS Settings → Privacy & Security → Health.
Health Connect data (Android, if you opt in)
If you enable Health Connect integration on Android, BiLT reads the following from Google's Health Connect:
- Workouts (type, duration, start/end time)
- Heart rate samples during your workouts
- Active energy burned
- Walking, running, and cycling distance
- Body weight
- Body fat percentage
This data is used to log cardio sessions and prefill weekly check-ins in your BiLT account. BiLT does not sell Health Connect data, use it for advertising, share it with data brokers, or use it for any purpose other than the features you've requested. You can disable Health Connect integration at any time in BiLT's settings, and you can revoke BiLT's Health Connect permissions at any time in the Health Connect app.
Device and diagnostic information
When you submit feedback or a bug report, we collect basic device information (device model, OS version, BiLT version) and any screenshot or description you choose to attach. This helps us reproduce and fix issues.
What we don't collect
- We don't collect your location.
- We don't collect your contacts, calendar, photos (other than ones you explicitly attach), or anything else outside the app.
- We don't use third-party analytics, advertising, or marketing trackers.
- We don't collect data about how you use other apps.
How your data is stored
Your data is stored locally on your device and synced to Google Firebase (Firestore and Firebase Storage) using your authenticated account. Firebase is operated by Google. Data in transit is encrypted with TLS. Data at rest is encrypted by Firebase. Only you, through your authenticated account, can access your data.
What we do with your data
- Provide the app. Storing, syncing, and displaying your training and nutrition data is the core function.
- Improve the app. Bug reports and crash diagnostics help us fix problems.
- That's it. We don't sell your data. We don't share it with advertisers. We don't share it with data brokers. We don't use it to build profiles for any purpose other than serving you the app.
AI features
Some BiLT features (such as nutrition lookups and meal photo analysis) send your text or photo input to Anthropic's Claude API via a proxy we operate. These requests are routed through our infrastructure so that no API keys are stored on your device. Anthropic processes the input to generate the response and does not retain it for training. We don't store the AI responses on our servers beyond what's needed to display them back to you and save them in your BiLT account.
Your rights
You can:
- Export your data — contact us at [email protected]
- Delete your account — available in the app under Settings, or by emailing us
- Withdraw consent for optional integrations (Apple Health, Health Connect) at any time in Settings
- Ask questions about what we hold about you — email [email protected]
If you're in the EU, UK, California, or another jurisdiction with specific privacy rights (GDPR, UK GDPR, CCPA), the rights granted by those laws apply to you. The list above covers them in plain terms; the underlying legal rights apply regardless.
Children
BiLT is not directed at children under 13. We do not knowingly collect data from children under 13. If we learn we've done so, we'll delete it.
Changes to this policy
If we materially change this policy, we'll update the "Last updated" date and, for significant changes, notify you in-app or by email.

By using BiLT, you agree to these terms. If you don't agree, don't use the app.
What BiLT is
BiLT is a fitness tracking app for logging resistance training, cardio, nutrition, and related body data. It is a tool, not a coach or a medical service.
Eligibility
You must be at least 13 years old to use BiLT. If you're under 18, you should have a parent or guardian's permission.

You're responsible for the activity that happens under your account. Use a strong sign-in method (Google or Apple) and don't share access to your account with others.
Subscription and billing
BiLT is a paid subscription app. Subscription terms (price, billing period, free trial length) are disclosed at the point of purchase through Apple's App Store or Google's Play Store. Subscriptions auto-renew unless you cancel them through your App Store or Play Store account. Refund requests are handled by Apple or Google according to their policies.
Health and safety disclaimer
BiLT is not medical advice. The app is a tracking and informational tool. Training routines, nutrition targets, and any AI-generated suggestions are not personalized medical, nutritional, or fitness prescriptions. Talk to a qualified professional (doctor, registered dietitian, certified trainer) before starting a new training or nutrition program, especially if you have a medical condition, are pregnant, are recovering from injury, or are taking medication that may interact with exercise or diet.
You exercise at your own risk. BiLT is not responsible for injuries, health outcomes, or other consequences of acting on information in the app.

- Use the app to harass, harm, or violate the rights of others
- Attempt to access accounts or data that aren't yours

Intellectual property
BiLT, the BiLT name, and the BiLT app are the property of the developer. Your training data, photos, and content you create in the app belong to you. By using the app, you grant us a limited license to store, sync, and display your content as needed to provide the service.
AI-generated content
Some BiLT features use AI to generate suggestions, analyses, or descriptions. AI output can be wrong. Don't rely on it for medical, financial, or safety decisions. Always verify important information with a qualified source.
Service availability
We aim for high availability but don't guarantee it. The service may be unavailable for maintenance, updates, or reasons outside our control. We may modify, suspend, or discontinue features at any time.
Limitation of liability
To the maximum extent permitted by law, BiLT is provided "as is" without warranties of any kind. We are not liable for indirect, incidental, special, or consequential damages arising out of or related to your use of the app. Our total liability for any claim is limited to the amount you've paid us in the 12 months before the claim.
Termination
You can stop using BiLT and delete your account at any time. We may suspend or terminate your account if you violate these terms or use the app in a way that risks harm to others, to us, or to the service.
Changes to these terms
We may update these terms from time to time. If we make material changes, we'll update the "Last updated" date and, for significant changes, notify you in-app or by email. Continued use after changes constitutes acceptance.
