Your training data should not be a mystery.

Section 1

Overview

Dyne is a strength training product operated by FASHION ART 3.0 INC. The mobile app helps users create workouts, log sets, track recovery, monitor progress, manage subscriptions, receive weekly workout reports, optionally connect supported health platforms, and sync data across devices. This policy covers the Dyne marketing website and the Dyne mobile app.

Dyne is a cloud-connected service. While the app may keep some information on the device for app performance, cached media, and active-session continuity, user account, profile, workout, template, preference, and related training data are generally synchronized to Dyne's remote backend services, including Supabase-backed infrastructure.

Section 2

Information we collect

Account and sign-in information

We collect the information needed to create and secure your account, such as your email address and authentication credentials. If you choose Google or Apple sign-in, we may receive basic profile details associated with that provider, such as your name, email address, and profile image.

Training, health, and profile information

We collect information you enter to personalize the app and support workout generation, including your display name, sex, age or date of birth, height, weight, experience level, goals, workout frequency, preferred split, gym type, equipment inventory, training preferences, workout templates, and exercise preferences.

We also collect workout and progress records created through the app, such as sessions, exercise selections, sets, reps, weight, RPE, durations, workout history, body weight logs, body-fat entries, and body measurements.

App settings and feature preferences

We collect settings and preference data needed to run the app experience, such as units, language, notification preferences, timer audio and vibration preferences, keep-screen-on settings, adaptive replan and smarter workout analytics flags, weekly workout report settings, time zone, and delivery schedule preferences.

Subscription, referral, and device information

We collect subscription and entitlement status needed to manage Dyne Pro, free-workout trials, purchase restoration, and referral rewards. In the current app implementation, this can include referral codes, referral activity, and a device identifier used to apply referrals and reduce abuse.

Optional permissions and connected services

Dyne may request access to your photo library if you choose to set a profile image, and it may request notification permission so workout and rest timers can continue to work when the app is backgrounded or your phone is locked. These permissions are optional at the device level, although notifications are required to complete the current app setup flow.

If the feature is enabled for your account and supported on your device, Dyne can also connect to Apple Health on iPhone or Health Connect on Android. If you choose to connect one of those services, Dyne may import height, weight, and body-fat data and may export completed workouts; on Android, the current code can also export calories-burned data with the workout record.

Website and support information

If you contact Dyne by email, we receive your email address and the contents of your message. If you use the in-app support chat when it is available, Dyne and the support-chat provider may receive your support messages and account-support metadata such as your display name, email address, user ID, subscription tier, app version and build, platform, locale, time zone, account creation date, member since value, and referral code.

When you visit the website, infrastructure providers may process standard technical information such as IP address, browser details, and device information needed to deliver the site. The reviewed website code does not currently show third-party advertising SDKs or a dedicated web analytics tracker.

Diagnostic and security information

The reviewed mobile app code includes Sentry integration for error and performance monitoring. In addition, some protected Android backend requests use Google Play Integrity checks to help validate the request and reduce abuse. These flows may involve limited diagnostic, device, or request-integrity information needed to monitor reliability and protect the service.

Section 3

How we use information

• To create accounts, authenticate users, and keep accounts secure.
• To personalize workout plans based on your profile, gym inventory, preferences, and training history.
• To log sessions, calculate progress signals, recovery status, streaks, and other in-app insights.
• To store, synchronize, and process data in Dyne's remote backend systems.
• To process subscriptions, free-workout trial access, referrals, and entitlement changes.
• To generate weekly workout reports and deliver them in-app or by email when you enable those options.
• To operate optional health integrations, including importing supported body metrics and exporting completed workouts.
• To provide support, respond to requests, troubleshoot issues, and improve reliability.
• To monitor app reliability, investigate errors, and help protect the service against abuse.
• To enforce terms, prevent abuse, and comply with legal obligations.

In the current app architecture, workout generation may involve sending your training history, profile, and gym setup to Dyne's backend function so it can generate a tailored workout plan.

Section 4

Sharing and service providers

We do not sell your personal information. We may share information with service providers that help us operate Dyne, subject to contractual or operational controls appropriate to the service involved.

Current providers reflected in the reviewed code

• Supabase for authentication, database storage, synchronization, and backend functions.
• Google and Apple when you choose their sign-in flows.
• RevenueCat, Apple App Store, and Google Play for subscriptions, purchase validation, and entitlements.
• Sentry for mobile error and performance monitoring.
• Zoho Mail for weekly workout report email delivery when you enable that feature.
• Tawk for embedded support chat when live chat is configured and you choose to use that channel.
• Apple Health and Android Health Connect if you connect those services in eligible app builds and accounts.
• Google Play Integrity on supported Android protected requests to help validate requests and reduce abuse.
• Website infrastructure providers, including Google Fonts, when the website loads in your browser.

We may also disclose information if needed to comply with law, protect users or Dyne, investigate fraud or abuse, or as part of a business transfer such as a merger, acquisition, or asset sale.

The current app code includes Sentry for error and performance monitoring and configures default personally identifying information sending as disabled. Some protected Android backend actions also use Google Play Integrity checks as part of Dyne's service-protection flow.

The reviewed mobile app code includes an optional Apple Health and Android Health Connect integration path behind an account feature flag. In supported builds, connected providers can be used to import height, weight, and body-fat data and to export completed workouts; the current Android path can also write calories-burned data with those workout exports.

Section 5

Retention and security

Dyne keeps information for as long as needed to provide the service, maintain account continuity, meet security needs, resolve disputes, and satisfy legal obligations.

In the current app implementation, much of your Dyne account and training data is synchronized to remote backend systems. Signing out clears local app data stored on the device, including local database content and locally saved profile media, but signing out does not by itself delete remotely stored account or workout data associated with your account.

We use reasonable technical and organizational measures to protect data, but no method of storage or transmission is completely secure.

Section 6

Your choices and rights

• You can update much of your profile, gym, workout, and body-log data inside the app.
• You can manage notification, photo-library, and connected health-data permissions in your device settings.
• You can manage weekly workout report delivery, supported health integrations, and related feature settings inside the app where available.
• You can manage paid subscriptions through the relevant app store account.
• You can sign out to remove local app data from your device, but that does not delete remotely stored account data.
• You can contact Dyne to request access, correction, deletion, or other privacy help, subject to applicable law.

To make a privacy request, email support@dyne.fitness.

For Dyne account deletion instructions and a summary of what data is deleted or kept, see the Account Deletion page.

Section 7

Children's privacy

Dyne is not intended for children under 16. The current app setup flow also enforces a minimum signup age of 16. If you believe a child has provided personal information to Dyne, contact us and we will review the request.
