Privacy Policy

1. Introduction

Cryptoniar Technologies ("we", "our", "us") operates Vyro, a fitness and workout app that lets you create routines, log workouts, and track your progress. Vyro does not require an account or login: you use the app on your device without signing in. This Privacy Policy explains what data we collect, what we do not collect, and how we use third-party services (Firebase, RevenueCat) in a way that respects your privacy.

2. Data Stored Only on Your Device

The following data is stored only on your device and is not sent to our servers or used for analytics:

• Your routines (name, days, exercises)
• Workout logs (exercises, sets, reps, weights, dates)
• Progress and statistics derived from your workouts
• Favorite exercises
• App preferences (e.g., theme, unit system: metric/imperial)
• Optional body weight, if you enter it in the app (used only locally for certain exercise calculations)

We do not collect your name, email, height, or any other personal or health data for our own systems. Vyro has no user accounts, so there is no profile data transmitted to us.

3. Firebase (Google)

Vyro uses Firebase services. Here is what each one does and what data is involved:

• Firebase Analytics — We use it to understand how the app is used (e.g., which screens are opened). We send only anonymous, technical information such as screen names and generic events. We do not send your name, weight, height, routines, workout data, or any identifiable or health-related information to Analytics.
• Firebase Crashlytics — When the app crashes, we send crash reports (stack traces, device type, OS version) to fix bugs. These reports do not include your routines, workouts, name, weight, height, or other personal data.
• Firebase Remote Config — We use it to deliver configuration (e.g., links to this Privacy Policy and Terms) without releasing a new app version. No personal data is sent; we only fetch these configuration values.

4. RevenueCat

Vyro offers optional paid features (e.g., Vyro PRO) through in-app purchases. We use RevenueCat to manage subscriptions and restore purchases. RevenueCat receives information related to your purchase (e.g., product ID, transaction status) from the App Store or Google Play. We do not send your name, weight, height, routines, or workout data to RevenueCat. For their privacy practices, see: www.revenuecat.com/privacy

5. Notifications

Vyro can show local notifications (e.g., workout reminders). These are scheduled on your device and do not involve sending your personal or workout data to our servers.

6. Data Storage and Security

Your routines and workout data stay on your device. Analytics and crash data are processed by Firebase under their security and privacy policies. We do not sell your data. No method of transmission over the Internet is 100% secure; we rely on industry-standard practices and our providers' safeguards.

7. Your Rights

Because we do not store your routines or workouts on our servers, there is no account to access or delete on our side. You can delete all app data by uninstalling Vyro. Depending on your jurisdiction, you may have additional rights (e.g., to object to processing). For any request or question, contact us via our website.

8. Children

Vyro is not directed at children under 13. We do not knowingly collect personal information from children under 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version on this page and may notify you via the app or website. Continued use of Vyro after changes constitutes acceptance of the updated policy.
