Privacy Policy

Chelnok Boxing Timer collects minimal personal information and stores workout data locally on your device.

Information We Collect

Chelnok collects minimal personal information. We collect:

• Device Information: your device model, OS version, and unique device identifiers for app functionality.
• Usage Data: workout sessions, timers used, and app settings stored locally on your device.
• Ad Data: Google Mobile Ads may collect information for personalized advertising.

We do not collect email, location, contacts, or other sensitive personal data.

How We Use Your Information

Your information is used to provide and maintain the app, display personalized advertisements, improve app functionality and user experience, and comply with legal obligations.

All workout data is stored locally on your device. We do not upload your personal training sessions to external servers.

Data Storage and Security

Your data is stored locally on your device using SharedPreferences. We implement reasonable security measures to protect your data. However, no method of transmission over the internet is 100% secure.

By using Chelnok, you acknowledge that you understand the inherent risks of data transmission and use.

Third-Party Services

Chelnok uses the following third-party services:

• Google Mobile Ads: for displaying advertisements. Google may collect data for ad targeting and measurement.
• Google Play Billing: for processing purchases, subscriptions, cancellations, and refunds.
• RevenueCat: for managing subscription status, entitlement checks, and purchase history.
• Flutter Text-to-Speech: uses device system text-to-speech for audio announcements.
• URL Launcher: opens links in an external browser.

These services are subject to their respective privacy policies. We recommend reviewing Google's privacy policy at https://policies.google.com/privacy.

Children's Privacy

Chelnok is designed for athletes 13+. We do not knowingly collect data from children under 13. If we become aware that a child under 13 has used the app, we will take steps to delete such data.

Parents: if your child has provided information to us, please contact us immediately.

Permissions

Chelnok requests the following permissions:

• VIBRATE: for haptic feedback during workouts.
• POST_NOTIFICATIONS: for workout notifications on Android 13+.
• WAKE_LOCK: to keep the screen awake during active timer sessions.

You can manage these permissions in your device settings.

GDPR Privacy Rights

If you are located in the European Economic Area, United Kingdom, or Switzerland, you may have rights to access, correct, delete, restrict, or object to certain processing of your personal data.

Because Chelnok stores workout data locally on your device and does not operate user accounts, most app data can be managed by deleting app data or uninstalling the app. For advertising data handled by Google, use your Google privacy and ads settings.

For details, see our GDPR Privacy Rights page.
