SmartBell

Privacy Policy

Effective July 11, 2026 · Draft pending legal review

1. What we process

• Quiz answers: first name, fitness goals, experience level, training days per week, session length, age band (not your date of birth), sleep/stress level, muscle priorities, and injury or physical-limitation flags (knees, shoulders, lower back, hips, wrists, elbows, ankles, neck).
• Pre-participation screening: your yes/no answer about certain health conditions, and if applicable, your statement that a doctor has cleared you.
• Chat messages you send to the AI coach, and short notes it saves about your context (for example, a sport you play).
• Technical data: your IP address is used transiently for security and rate limiting and is stored only as a hashed value for a short period. We do not log the content of your messages.

We do not collect your date of birth, address, phone number, payment details, precise location, or biometric data.

2. Where your information is stored

Your profile, plan, and recent chat are stored in your browser's local storage on your device. They are cleared when you choose "Start over," when you clear your browser data, and automatically after 24 hours of inactivity — which protects you when using a shared gym device. SmartBell does not maintain a member database.

3. AI processing

To answer your questions, we send your message, your training profile (including injury flags), your current plan, and any saved notes to Anthropic PBC, which operates the Claude AI model, acting as our processor. Anthropic processes this data to generate a response under its commercial terms and does not use it to train its models. We instruct the AI to treat your information as data, never as instructions.

4. Why we process it

To build your workout plan; to answer your questions; to keep you safe (screening and injury-aware exercise selection); and to operate and secure the service.

5. Sharing

We share data with Anthropic (AI processing) and Netlify (hosting; processes requests transiently). We may disclose information if legally required. We do not sell your personal information or share it for cross-context behavioral advertising, and we do not give your individual data to your gym without telling you.

6. Retention and deletion

Because your data lives on your device, you control it — use "Start over" in the app or clear your browser storage to delete it. Hashed IP counters expire within 24 hours. We keep a record that a disclaimer was accepted (including a first name, timestamp, and disclaimer version) for legal purposes.

7. Your rights

You may request access, correction, deletion, or portability of your information by contacting us — though in most cases we hold no server-side copy of it. You will not be discriminated against for exercising these rights.

8. Health-adjacent information

Injury flags and screening answers relate to your physical condition. We collect them only to make exercise selection safer. Please do not include medical details, diagnoses, or other sensitive information in free-text chat messages.

9. Children

SmartBell is not intended for anyone under 16, and we do not knowingly collect information from children.

10. Security

We use encryption in transit (HTTPS), server-side secret management, rate limiting, and no third-party trackers or advertising cookies. No system is perfectly secure.
