Simple Stopwatch

This Privacy Policy governs the use of the mobile application Simple Stopwatch ("the Application") for Android devices, developed by Spacedancer. The Application is a precise stopwatch and countdown timer featuring offline voice control and audio announcements.

1. Information Collection and Use

The Application operates under a strict "Privacy First" and "Offline First" model. You can utilize all core features—including the stopwatch, countdown timer, lap recorder, and voice controls—without creating an account, registering, or providing any personal identification information (such as your name, email address, or phone number).

Local Preferences & App Settings

Your app preferences (such as sound state, voice command toggles, active tab navigation, and target countdown values) are saved exclusively within the Application's private internal storage on your physical device via Android's SharedPreferences. This data is never uploaded, shared, or accessible by the developer or any third parties.

2. Device Permissions and Offline Voice Processing

To deliver advanced timing features and hands-free operations, the Application requests specific device permissions. These permissions are used strictly on-device:

• Microphone Access (RECORD_AUDIO): Required solely to detect hands-free voice commands (such as "start", "pause", "lap", "stop", "reset"). Voice control uses an embedded, offline speech recognition engine (Vosk). Audio data is streamed in real-time directly to the local engine on your phone. Audio is never recorded, stored, or sent over the internet to any remote servers.
• Vibration Control (VIBRATE): Used strictly to provide tactile haptic feedback when interacting with buttons or when a countdown timer reaches zero.
• Text-To-Speech (TTS) Integration: Used to deliver spoken audio countdown announcements and notifications locally via your Android device's built-in Text-To-Speech engine.

3. Third-Party Advertising and Analytics

To support free development, the Application integrates the Google AdMob SDK to display banner advertisements at the bottom of the main screens.

When an active internet connection is available, Google AdMob may automatically collect limited technical data to serve non-intrusive advertisements, which may include:

• IP addresses (used for coarse, general location delivery)
• Device identifiers (such as the Android Advertising ID)
• Ad interactions and diagnostic data

This data is collected directly by Google AdMob solely to render ads, limit ad frequency, and prevent fraudulent activity in compliance with Google's Privacy Policy. For detailed information on how Google handles advertisement data, please visit:

4. Offline Operations

The Application is fully functional without an active internet connection. All stopwatch measurements, countdown timers, voice command recognition, and audio announcements work completely offline. When your device is disconnected from the internet, third-party ad banners simply do not load, and zero network traffic is generated by the app.

5. Children's Privacy

The Application does not knowingly collect or solicit personal information from anyone, including children under the age of 13. Because all voice processing and timing functions run entirely on your physical device, no personal data is transmitted. If you believe third-party ad services (Google AdMob) have inadvertently received data, please refer to Google's Ad Privacy policies.

6. Data Control and App Reset

Since all timer histories, sound toggles, and app state preferences are saved locally on your phone, you maintain full control over your data. You can erase all saved settings at any time by clearing the Application's storage via your device settings (Settings → Apps → Simple Stopwatch → Storage → Clear Data) or by uninstalling the application.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect app updates or regulatory requirements. Any updates will be posted directly to this URL and will take effect immediately upon posting.
