Privacy Policy

Last updated: May 14, 2026

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 privacy@biltbody.com.

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

This data is used to log cardio sessions 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 similar workout and heart rate data from Google's Health Connect. The same rules apply: this data is used only to log sessions in your BiLT account and is never sold, used for advertising, or shared with third parties.

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 privacy@biltbody.com
• 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 privacy@biltbody.com

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.

Terms of Service

Last updated: May 14, 2026

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.

Your account

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.

Acceptable use

Don't:

• Reverse engineer, decompile, or attempt to extract source code from the app
• Use the app to harass, harm, or violate the rights of others
• Attempt to access accounts or data that aren't yours
• Use the app for any unlawful purpose

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.
