_Last updated: 2026-05-19_

## 1. Information We Collect
### 1.1 Information you provide
**None.** Block Puzzle does not ask for an account, name, email, phone
number, or any other personally identifying information.
### 1.2 Information stored locally on your device
The App stores your high score, lifetime gameplay statistics, settings
(theme, sound, vibration, language), tutorial-shown flag, unlocked
achievements, and completed daily-challenge dates in your device's local
storage (Android DataStore Preferences). This data **never leaves your
device** and is removed when you uninstall the App or use the "Reset
Data" button inside Settings.
### 1.3 Information collected automatically
We use **Google AdMob** to display advertisements. AdMob may collect
device identifiers (advertising ID, IP address, basic device information)
to serve relevant ads. AdMob's data handling is governed by Google's
privacy practices:
- [Google Privacy Policy](https://policies.google.com/privacy)
- [How Google uses information from sites or apps that use our services](https://policies.google.com/technologies/partner-sites)
---
## 2. Advertising
The App contains four types of AdMob ads:
- **Banner** (Home and Stats screens)
- **Interstitial** (occasionally between games)
- **Rewarded** (optional, when you tap "Revive" on Game Over)
- **App Open** (occasionally when the App returns from background)
Ads support free development and distribution of the App.
You can opt out of personalized advertising through your Android device's
settings:
- **Settings → Google → Ads → Reset advertising ID / Opt out of Ads
Personalization**

## 3. Children's Privacy
The App is rated for all ages but is not specifically directed at
children under 13. We do not knowingly collect personal information from
children. The advertising network (Google AdMob) is configured according
to Google Play's Families Policy where applicable.
---
## 4. Data Security
All gameplay data is stored locally on your device. We do not operate
servers and do not transmit personal data of our own. Ad-related data is
handled by Google AdMob under its own security practices.
---
## 5. Your Rights
Because we do not collect personal data ourselves, there is no account
to delete on our side. To remove all local data created by the App:
1. Open the App → **Settings → Reset Data**, **OR**
2. Uninstall the App from your device.
For questions about AdMob data, please refer to Google's privacy
controls linked above.

## 6. Changes to This Policy
We may update this Privacy Policy from time to time. Updates will be
reflected on this page with a revised "Last updated" date.
