Privacy Policy

Coach1 · Last updated November 6, 2026

Coach1 is a personal training and nutrition coaching app operated by the operator of Coach1. This policy explains what we collect, why, and your choices.

What we collect

• Account: your email and sign-in details, handled by our authentication provider (Clerk).
• Beta sign-up: your name and email from the sign-up page or the app's waitlist, and whether you asked for news and offers.
• Feedback and reviews: messages you send with Send feedback, your check-in answers, and your 6-month review, including a photo if you choose to add one.
• Profile and health information you give us: age, sex, height, weight, body fat, body measurements, training goals, injuries and health-screen answers, diet preferences and allergies.
• Training and nutrition activity: workouts, sets, reps and weights, form notes, meals you log, and your conversations with the in-app coaches.
• Apple Health (optional): if you turn it on, we read the data you allow: weight, body fat, sleep, resting heart rate, heart rate variability, steps, active energy, VO2 max, and workouts recorded by other apps and devices (for example Apple Watch, WHOOP or Garmin, if they share with Apple Health). We store daily totals, not minute-by-minute data, and use them only to coach you (for example, an easier session after a short night). We also save the workouts you finish in Coach1 to Apple Health, if you allow it. Apple Health data is never used for advertising or sold.
• Location (optional): used on your phone to find gyms and restaurants near you. Your location is not sent to our servers; only the gym or restaurant you choose is.
• Usage and diagnostics: which features you use and crash reports, to improve the app.

What stays on your phone

If you talk to your coach instead of typing, your voice is turned into text on your phone (by Apple's speech recognition, on-device on supported iPhones), and only the text is sent, like a typed message. Replies can be read aloud by your phone's built-in voice.

Camera video for rep counting, form checks and body scans is processed on your device and never uploaded. Progress photos are stored only on your phone. The one exception is a photo you choose to add to your 6-month review: it is stored privately on our servers, seen only by the Coach1 team, and used in marketing only if you say yes. If you ask for an AI form review or log a meal by photo, the still images you choose are sent for analysis and are not stored by us.

How we use it

• To create and adjust your training program, meal plans and coaching.
• To show your progress and send reminders you turn on.
• To run the free beta: hold your spot, email you about it (your spot, the waitlist, your free months ending), and, only if you said yes, send you news and offers.
• With your permission only: to quote your review (and show your photo, if you added one) in our marketing. You can take back that permission at any time by contacting us.
• To run, secure and improve the service, including measuring how well features like rep counting work.

We do not sell your personal information and do not use it for advertising.

AI processing

Coaching features use AI models provided by Anthropic. The information needed for a request (for example your profile and recent workouts) is sent to Anthropic to generate a response. Anthropic does not use this data to train its models.

Service providers

We use Clerk (sign-in), Cloudflare (servers and review-photo storage), Resend (email), Neon (database), Anthropic (AI), Apple (maps search on your device, App Store) and Open Food Facts (barcode lookups made from your phone). They process data only to provide their service to us.

Your choices

• Edit your profile in the app at any time.
• Turn off Apple Health sync, reminders or location access in the app or in iOS Settings, or choose which Apple Health data to share in the Health app. You can also ask your coach in the app to stop using your sleep and heart data.
• Delete your account in the app under Profile → Delete account. This permanently deletes your account and data from our systems. Anonymous usage totals may be kept.

Security and retention

Data is encrypted in transit and at rest. We keep your data while your account is active and delete it when you delete your account.
