Privacy Policy
This Privacy Policy explains what information Volt Glow Charging Animation (the "app") handles, why, and who receives it. It describes the app's actual technical behaviour. The app has no user accounts and the developer does not run its own server: the developer does not receive your name, email address, photos, or any content you create in the app.
1. Summary
- No account or sign-in is needed.
- Your settings, favourites, battery alarms, charging history, and the photos or videos you add to the app stay on your device.
- The app shows ads through Google AdMob and asks for your consent where the law requires it, using Google's User Messaging Platform.
- Firebase Analytics and Firebase Crashlytics receive anonymous usage statistics and crash reports.
- The optional VIP subscription is sold through Google Play and only removes ads.
2. Information collected automatically
The following data is collected by the third-party software development kits (SDKs) built into the app, not by a server of the developer:
- Advertising ID and device identifiers: used to serve ads, limit how often an ad is shown, measure ads, and prevent fraud; received by Google AdMob. Firebase also uses an app instance ID to count usage; received by Google Firebase.
- Approximate location derived from your IP address: used by the ad network to choose ads suitable for your region and to apply regional privacy rules; received by Google AdMob. The app never requests your GPS or precise location.
- Device and app information (device model, Android version, language, app version, network type): used for ad delivery, statistics, and diagnosing problems; received by Google AdMob and Google Firebase.
- App interactions (for example which screens are opened, the VIP screen being opened, ad impressions and their estimated value): used to understand how the app is used and which ad placements work; received by Google Firebase Analytics. These events contain no personal content.
- Crash reports and diagnostic logs: used to find and fix errors; received by Google Firebase Crashlytics. Reports contain technical information such as the error, the device model, and the Android version, and do not contain your photos, videos, or settings.
- Purchase records of the VIP subscription: used to confirm that your subscription is active; handled by Google Play Billing.
3. Information stored only on your device
The following never leaves your device through the app and is not sent to the developer:
- Your settings: the chosen charging animation, style, language, sounds, battery alarm levels, vibration choice, emoji battery icon, favourites, and similar preferences.
- Battery readings and charging history: battery level, temperature, voltage, health, and charging sessions are read from Android and saved only on the device.
- Photos and videos you choose: when you create an animation or a photo slideshow, you pick images or a video with the Android system photo picker. The app copies only the items you pick into its private storage on the device to use them as a charging screen. They are not uploaded anywhere, and they are excluded from Android cloud backup and device-to-device transfer. You can remove them in the app at any time.
- Sounds: the plug-in, unplug, and full-battery sounds are generated inside the app. The app does not use the microphone.
Other app settings may be included in Android's own backup if you have enabled backup for your Google account; that backup is controlled by Android and Google, not by the developer.
4. Permissions
- Display over other apps (SYSTEM_ALERT_WINDOW): optional. Used only to show your chosen charging animation on screen when you plug in the charger. You turn it on yourself in the Android settings page. It does not capture, record, or read your screen or other apps.
- Notifications (POST_NOTIFICATIONS, Android 13 and later): optional. Used for the full-battery and low-battery alarms you set, and for the emoji battery icon in the status bar. Requested only when you turn one of these features on.
- Foreground service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_SPECIAL_USE): runs only while you keep the charging screen, a battery alarm, a charging sound, or the emoji battery icon turned on. It listens for the charger being plugged in or unplugged and for battery level changes, and shows an ongoing notification while it runs.
- Run at startup (RECEIVE_BOOT_COMPLETED): restarts that service after the phone restarts, so the features you turned on keep working.
- Internet and network state (INTERNET, ACCESS_NETWORK_STATE): used to load ads, send anonymous statistics and crash reports, and check subscriptions with Google Play. The charging animations are built into the app and work offline.
- Google Play Billing (BILLING): used only to buy and restore the VIP subscription.
- Advertising ID (AD_ID and the related Android ad services permissions, added by the Google Mobile Ads SDK): used by AdMob as described in section 2.
The app does not request access to your contacts, camera, microphone, precise location, phone calls, SMS, or your files. Photos and videos are reached only through the system photo picker, item by item, when you choose them.
5. Advertising
The app is free and shows ads through Google AdMob: native ads inside some screens and, after some actions, an occasional full-screen ad with a minimum time between ads. Ads are never shown to users with an active VIP subscription.
If you are in the European Economic Area, the United Kingdom, Switzerland, or another region where consent is required, the app shows Google's consent form (User Messaging Platform) before personalised ads are requested. You can change your choice at any time in the app: Settings → Privacy options (this item appears where a consent choice applies).
You can also reset or delete your advertising ID, or opt out of personalised ads, in your Android settings (Settings → Google → Ads, or Settings → Privacy → Ads, depending on the device).
California residents (CCPA/CPRA): the developer does not sell personal information for money. Sharing the advertising ID with Google AdMob for targeted advertising may count as "sharing" under California law; you can limit it by opting out of personalised ads as described above.

6. Purchases
The VIP subscription (weekly or yearly) is sold and billed by Google Play. It only removes ads; every feature and every animation stays free for everyone. Your payment details are handled by Google and never reach the app or the developer. The app receives only the purchase status from Google Play to know whether ads should be turned off.
7. Children
The app is not directed at children under 13 (or the minimum age required in your country) and the developer does not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will help remove it.
8. Data retention and deletion
- Data stored on your device stays there until you delete it in the app, clear the app's data in Android settings, or uninstall the app. Uninstalling removes it all.
- Data received by Google AdMob and Google Firebase is kept according to Google's retention policies. Firebase Analytics data is kept for the retention period set in the Firebase project, and crash reports are kept for a limited time by Crashlytics.
- Because the app has no accounts, the developer cannot link this data to your identity. You can reset your advertising ID in Android settings to break the link with past ad data.
9. Your rights
Depending on where you live (for example under the GDPR in the EU, the UK GDPR, the CCPA/CPRA in California, or Vietnam's personal data protection rules), you may have the right to access, correct, delete, or restrict the processing of your personal data, to object to processing, to withdraw consent, and to complain to a data protection authority. You can withdraw ad consent in Settings → Privacy options. For any other request, email us; we will respond within a reasonable time and explain what we can do, given that the developer holds no account data about you.
10. Security
The Google SDKs used by the app send data over encrypted connections (HTTPS). Data stored on your device is kept in the app's private storage, which other apps cannot read. No method of transmission or storage is completely secure, but we use the protections provided by Android and Google.
11. Changes to this policy
We may update this Privacy Policy when the app changes, for example when an SDK or a permission is added or removed. The updated version will be posted at this address with a new effective date. Please review it from time to time.
