## What the app does
Sparkvali is an offline puzzle game. You drag light bulbs around the screen until none of their wires cross. It includes 120 levels, a daily puzzle, optional skins, and optional in-app purchases.
## The short version
- Sparkvali does not collect, transmit, sell, or share any personal data.
- The app does not request internet access. It has no accounts, no ads, no analytics, and no crash-reporting services.
- Your progress stays on your device.
- Purchases are processed entirely by Google Play.
## Data stored on your device
The app stores the following on your device only, in its private app storage:
- Game progress: levels solved, stars, best moves and times, any puzzle in progress, and your purchased-hint balance.
- Daily puzzle history and your streak.
- Settings: skin, theme, sound, music, volume, haptics, reduced motion, colour-blind palette, timer visibility, and reminder time.
- A cached flag recording whether you own the Premium Collection. It is used only to show your purchase instantly at launch and is refreshed from Google Play every time the app starts.
This data never leaves your device through the app. We cannot see it.
## Device backup
If you have turned on Android's backup, Android may include your progress and settings in your Google account backup, and in device-to-device transfers. Google handles that backup under its own privacy policy. The purchase cache is excluded from backup. You can turn Android backup off in your device settings at any time.
## Notifications
The app can show one optional daily reminder when today's puzzle is unsolved. It asks for the notification permission only when you turn the reminder on in Settings. The reminder is scheduled on your device and sends no data. You can turn it off in Settings or in Android's notification settings. If your device restarts, the reminder resumes the next time you open the app.
## Purchases through Google Play
Sparkvali offers optional one-time purchases: the Premium Collection, and two hint packs. Payments are processed by Google Play under Google's terms and privacy policy (https://policies.google.com/privacy). We never receive your name, email address, or payment details. The app receives only a purchase confirmation from Google Play on your device, which it uses to unlock what you bought. Purchase verification happens on your device. We do not run a server.
## Permissions
The app's final Android manifest declares only these permissions:
- **Post notifications** (`POST_NOTIFICATIONS`): requested only if you turn on the daily reminder.
- **Google Play billing** (`com.android.vending.BILLING`): lets the app ask the Google Play Store app to show a purchase.
- **View network connections** (`ACCESS_NETWORK_STATE`): added automatically by the Google Play Billing Library. It can only check whether the device is online. It cannot send or receive data.
- An internal permission, generated by AndroidX, that protects the app's own broadcast receivers.
The app does **not** have the internet permission. Some Google components bundled with the Play Billing Library are designed to send diagnostic information to Google. Without the internet permission, they cannot transmit anything from this app. No location permission is declared, so the app cannot access your location.
## Advertising, analytics, and third parties
Sparkvali contains no advertising, no analytics, no tracking, and no social or sign-in features. Apart from Google Play Billing, the app uses only Google's AndroidX/Jetpack libraries and the Kotlin and Dagger/Hilt libraries. None of these collects data for us.
## Sharing results
If you tap Share after solving a puzzle, the app opens Android's share sheet with a short text message (for example, your moves, time, and streak). Nothing is sent unless you choose an app to share with and confirm. That app's privacy policy then applies.
## Data retention and deletion
Data is kept on your device until you delete it. You can delete it at any time:
- In the app: Settings › Reset all progress. This erases progress, streaks, stats, and settings. Purchases can be restored from Google Play.
- Uninstall the app. Android deletes all of its data from the device.
- Clear the app's storage in Android Settings › Apps › Sparkvali › Storage.
There are no accounts and no copies held by us, so there is nothing for us to delete on our side.
## Children
Sparkvali is rated for all ages, but it is not directed at children under 13, and its target audience is ages 13 and over. We do not knowingly collect personal information from anyone, including children.
## Your rights
### European Economic Area, United Kingdom (GDPR / UK GDPR)
We do not process personal data about you, so we do not act as a controller of your data through this app. You still have the rights of access, rectification, erasure, restriction, portability, and objection. Because we hold no data about you, a request will normally be answered by confirming that. You may also complain to your local data protection authority.
### California (CCPA / CPRA)
We do not collect, sell, or share personal information as those terms are defined in the CCPA/CPRA, and we do not use it for cross-context behavioural advertising.
### India (Digital Personal Data Protection Act, 2023)
We do not collect or process digital personal data through this app. For any question or grievance about privacy, contact us at the email below and we will respond within a reasonable time.
## Security
Because no data is transmitted, the main safeguard is Android's app sandbox, which keeps the app's files private to the app. The app declares no internet permission and disallows cleartext network traffic.
## Changes to this policy
If the app ever changes what it collects, for example by adding a feature or a third-party service, we will update this policy, change the effective date above, and update the app's Data safety information on Google Play before or when the change is released.
