Privacy Policy

Introduction

Nopi Fitness ("we", "our", or "us") operates the Nopi Fitness mobile application. This Privacy Policy explains how we collect, use, and protect your information when you use our app.

Information We Collect

Account Information

When you create an account, we collect your email address, display name, and profile photo. Authentication is handled by Clerk, a third-party authentication provider. You may also sign in with Apple or Google, in which case we receive only the information you authorize those providers to share.

Workout & Fitness Data

We collect the workout data you enter, including exercises, sets, reps, weights, cardio sessions, and training plans. This data is used to provide the core functionality of the app, such as tracking your progress and generating performance insights.

Physical Metrics

You may optionally provide physical metrics such as age, weight, height, body fat percentage, and muscle mass percentage. These are used to personalize your experience, including calorie estimates and AI coaching recommendations.

Health Data (Apple Health)

If you grant permission, the app reads and writes data through Apple HealthKit, including body weight, body fat percentage, muscle mass, and heart rate during workouts and cardio sessions. Heart-rate samples recorded during a session are stored on our servers as part of that session's history. Health data is never used for advertising and is only used to power the features described in this policy (progress tracking, calorie estimates, and AI coaching).

Location Data

If you grant permission, the app uses your device's location, including while the app is in the background, to record a GPS route during outdoor cardio sessions (e.g. runs). Route data is stored on our servers as part of that cardio session so you can review it later. Location access is only used for this feature and is never used for advertising.

Training Profile & Goals

You may optionally provide training preferences and goals — such as experience level, available equipment, session frequency, exercise preferences, injuries, and target weights or lifts — to personalize your training plan and AI coaching.

AI Coach Conversations

When you use the AI coach feature, your messages, any images you attach, voice input you dictate, and relevant workout and training profile data are sent to our AI provider, OpenAI, to generate personalized responses. Conversations are stored to maintain chat history within the app. Voice input is transcribed on your device before being sent as a text message.

How We Use Your Information

• To provide and maintain the app's core functionality
• To track your workout progress and personal records
• To power the AI coach with personalized recommendations based on your training history
• To enable social features such as sharing workouts with friends
• To improve the app and fix issues

Data Sharing

We do not sell or share your personal information for advertising purposes. Your data is shared only in the following cases:

• Friends: When you share a workout or cardio session, or when your account is set to share activity automatically, an accepted friend can see a summary of that activity — including duration, calories, total volume, personal records, and your profile photo — in their activity feed.
• Service Providers: We use third-party services to operate the app: Clerk (authentication) and OpenAI (AI coaching feature). These providers process data only as needed to provide their services, and may process or store data outside your home country, including in the United States.
• Legal Requirements: We may disclose information if required by law.

Data Security

We use industry-standard security measures to protect your data, including encrypted connections (HTTPS/TLS), rate limiting, and secure authentication. Access to user data is restricted to authenticated requests and scoped to your own account.

Data Retention & Deletion

Your data is retained as long as your account is active. You can request deletion of your account and all associated data — including workout history, physical metrics, health and location data, and AI coach conversations — by contacting us at stijn@nopi.studio. We will complete deletion requests within 30 days. Some data may persist briefly in backups before being purged on the normal backup rotation schedule.

Your Rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise any of these rights, contact us at stijn@nopi.studio. Nopi Fitness is operated from the United States; if you are located in the European Economic Area, the United Kingdom, or elsewhere outside the United States, be aware that your data will be processed in the United States by us and by our service providers (Clerk and OpenAI).

Children's Privacy

Our app is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected data from a child, please contact us so we can delete it.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this page.
