The short version

Workout Roulette (also called نوّع / Mixify) saves your workouts, custom plans, and settings on your phone. You don't create an account, and we never see what you train.

There are only three times data goes anywhere else, and each one is explained below:

• Health Connect — only if you turn it on, so completed workouts show up with the rest of your health data.
• Google Drive backup — only if you turn it on, and the backup goes to your own personal Google Drive, not to us.
• Anonymous statistics — crash reports and basic usage numbers that don't identify you.

Reminders and rest timers run entirely on your device. We do not sell your data, and we do not share it with advertisers or data brokers.

Syncing with Health Connect

Health Connect is Android's centralized hub for health and fitness data. If you choose to enable it, Workout Roulette can record your completed workout sessions there so they appear alongside your daily activity, steps, and recovery metrics.

This integration is completely optional. If you skip it, the app works exactly the same.

Device notifications & timers

Workout Roulette requests notification access (POST_NOTIFICATIONS) to deliver helpful, local training prompts:

• Daily workout reminders: A local notification (defaulting to 6:00 PM or your chosen time) prompts you to stay consistent. It is suppressed automatically on days you have already logged a session.
• Rest timer cues: Gentle audio and haptic feedback alert you when your rest period between sets has elapsed.
• 100% on-device: All scheduling and notifications execute strictly within your phone's Android operating system. No notification content, scheduling data, or interaction history is ever sent to external servers.
• Full user control: You can adjust the reminder time or disable notifications at any time in the app's Settings or your Android System Settings.

Backing up to Google Drive (optional)

Changing phones, or worried about losing months of training progress? You can save a backup to your own personal Google account and restore it later. This is disabled until you explicitly turn it on.

• The app gets a locked drawer, not your whole Drive. It can only access a hidden, private folder dedicated solely to this app (drive.appdata). Your personal documents, photos, and files are completely unreachable.
• The backup is strictly yours. Backup files reside in your personal Google Drive storage, not on developer servers. We cannot view, download, or delete your files.
• We never see your Google credentials. Authentication is handled directly and securely by Google Play Services.
• You can revoke access anytime. Turn off the backup feature in Settings, or delete the app's saved data from your Google Drive account settings.

Where your data lives

Your complete training logs—including workout history, custom plans, per-set weights and reps, exercise notes, progressive overload targets, 2D anatomical muscle volume distributions, custom timers, and preferences—are stored inside the app's secure private sandbox on your phone (Room database and encrypted DataStore). Other applications cannot access this data, and it is never uploaded automatically.

Want it all deleted? You have two instant options:

• Clear all data via Settings → Clear app data inside the app (or in your phone's Android App Settings).
• Uninstall the application from your device.

Once cleared, no trace remains on your phone or on any server—unless you created a Google Drive cloud backup yourself.

App statistics & diagnostics

We use Google Firebase (Crashlytics & Analytics) to diagnose application crashes, measure stability, and understand aggregate feature adoption. All diagnostics are completely anonymous:

• What we see: Device model, Android OS version, application version, crash stack traces, and anonymous aggregate counts (such as total roulette spins or sessions completed).
• What we never see: Your name, email, workout notes, lift numbers, training history, or any health metrics.

Children

Workout Roulette is designed for general fitness enthusiasts and is not directed at children under the age of 13. We do not knowingly collect personal or health information from children. If a child logs data on your phone, clearing the app's data wipes everything immediately.

Questions and updates

When the app introduces new capabilities that interact with device data, we will update this document and adjust the revision date above.
