COMBAT CONDITIONING

C24 CARDIO

Privacy Policy

Effective date: 27 October 2026

This Privacy Policy describes how C24 Cardio (“C24 Cardio”, “we”, “us”, or “the app”) handles information when you use the C24 Cardio app on iPhone or Android (Android package name com.c24cardio.android) or the web version at sergiocoder007.github.io/C24-Cardio/.

WHO WE ARE

C24 Cardio is a combat-conditioning round timer. There is no account to create and no sign-in. For privacy questions, contact us through sergiocoder007.github.io/C24-Cardio/.

WHAT THIS APP DOES

You choose the number of rounds, the round duration and the rest between rounds, then run a timed workout with sound cues. In Training mode the app also calls out punch and kick combinations during each round. When you complete a workout, the app keeps a record of it on your device so it can show your training totals, progress and streak.

INFORMATION STORED ON YOUR DEVICE

The app stores the following on your device only, using the device’s standard web storage:

• Completed workouts: when each workout finished, how many rounds you completed, the round and rest durations used, and whether it was a Sparring or Training workout.
• Your settings: your last round, duration and rest choices, whether sound is on, and your Training mode choices (style, level and call pace).

Workouts you end early with “End workout” are not saved. This information never leaves your device through our code. We do not run a server or database for C24 Cardio, and we cannot see or recover your workout history.

INFORMATION WE DO NOT COLLECT

• No accounts, sign-in, email, phone number or profile information
• No location, contacts, camera, microphone or photo access
• No analytics, advertising or crash-reporting SDKs
• No advertising identifiers and no tracking across apps or websites
• No push notifications from a server and no Firebase or Google mobile services (the only notifications are the on-device workout timer and “workout complete” notices described below)
• No in-app purchases or payments

HOW INFORMATION IS USED

The workout records and settings on your device are used only to run the timer and to show your training totals, progress, records and streak inside the app. We do not use them for advertising, profiling or marketing.

SOUNDS AND SCREEN

Timer sounds are generated by the app or loaded from files bundled with it; nothing is recorded. Training mode combinations are spoken by your device’s built-in text-to-speech voice (or by voice clips bundled with the app); the text is generated on your device from the app’s built-in combination list and is not sent anywhere by our code. While a workout is running, the app asks your device to keep the screen on so the timer and sounds continue. The screen can sleep again when the workout ends.

THIRD-PARTY SERVICES

The app’s screens, images, fonts and sounds are bundled with the app and load no content from other websites. Apple, Google or your web browser may process technical information (such as your IP address) when you download, update or open the app, under their own terms. The mobile apps use Capacitor to display the app inside the system web view; no Capacitor analytics, advertising or push plugins are included.

ANDROID PERMISSIONS

The Android app includes the standard INTERNET permission that the Capacitor web view requires. C24 Cardio’s code does not use it to send your data anywhere. Keeping the screen awake during a workout does not require a runtime permission. To keep the timer, sounds and spoken combinations running while the screen is locked, the Android app uses a foreground service (FOREGROUND_SERVICE and FOREGROUND_SERVICE_MEDIA_PLAYBACK) that shows an ongoing notification with the round, time left and Pause/Stop buttons, and a WAKE_LOCK so the device does not sleep mid-workout. On Android 13 and later the app asks for the POST_NOTIFICATIONS permission to show that notification and the “workout complete” notice; if you decline, the timer and sounds still work. The service runs only during a workout and stops when it ends. The app does not request location, camera, microphone, contacts, photos or storage permissions.

BACKUPS

If your device or operating system backs up app data (for example Android backup or an iCloud device backup), your on-device workout history may be included in that backup. Those backups are handled by Apple or Google under your account settings, not by us.

SHARING WITH THIRD PARTIES

We do not sell or share personal information. Because your workout history stays on your device, we have nothing to share.

DATA RETENTION AND DELETION

Your workout history stays on your device until you delete it. To delete it, uninstall the app, or clear the app’s data (Android: Settings › Apps › C24 Cardio › Storage › Clear storage). For the web version, clear the site data for sergiocoder007.github.io in your browser. We keep no copy, so there is nothing for us to delete on a server.

YOUR PRIVACY RIGHTS

Depending on where you live, you may have rights to access, correct or delete personal data. Because C24 Cardio holds no account or server-side data about you, you can exercise these rights directly on your device as described above. You can also contact us at sergiocoder007.github.io/C24-Cardio/.

CHILDREN’S PRIVACY

C24 Cardio is a general fitness timer. We do not knowingly collect personal information from children, and the app has no sign-up flow.

CHANGES TO THIS PRIVACY POLICY

If C24 Cardio later adds accounts, cloud sync, analytics, advertising or any other data collection, we will update this page and its effective date before that change ships.
