# Privacy Policy — Block Puzzle : Grid Blast
**Effective date:** 2026-09-01
**Contact:** aziz_ahmad@outlook.sg
This privacy policy applies to the mobile application **Block Puzzle : Grid Blast** (the "App"), available on the Apple App Store and Google Play Store, published by Aziz Ahmad ("we", "us").
## Summary
- The App does **not** require an account and does **not** collect, store, or transmit any personal information itself.
- Your best score and settings are stored **only on your device**.
- The App shows **non-personalized ads** served by Google AdMob. The advertising SDK may process a limited set of device data to serve and measure those ads.
- The optional "Remove Ads" purchase is processed entirely by Apple or Google; we never see or store your payment details.
- The App contains no analytics SDK and no social features. It offers an optional, opt-in daily reminder using local notifications only — no push service or server is involved.
## Data stored on your device
The App saves the following data locally on your device only:
- your best score and lifetime gameplay stats (games played, lines cleared, best combo streak, perfect clears, pieces placed, and similar counters used to track achievements),
- which achievements you've unlocked,
- your preferences: sound effects, music, haptics, and app language,
- whether you've opted in to the daily reminder notification,
- whether you've completed the first-launch tutorial,
- whether the "Remove Ads" purchase is active.
This data never leaves your device, is not backed up by us, and is deleted when you uninstall the App.
## Advertising (Google AdMob)
The App uses **Google AdMob** to display interstitial and optional rewarded advertisements. Ads are requested in **non-personalized mode**: we do not request ads based on your interests or profile, and the App does not use Apple's App Tracking Transparency framework because it does not track you across apps.
To serve and measure even non-personalized ads, Google's SDK may collect and process certain data, such as:
- IP address (coarse location inference, fraud prevention),
- device information (model, OS version, language),
- advertising identifier (IDFA/GAID) subject to your device settings,
- ad interaction data (impressions, clicks).
This processing is governed by Google's policies:
- How Google uses information from sites or apps that use its services: <https://policies.google.com/technologies/partner-sites>
- Google Privacy Policy: <https://policies.google.com/privacy>
You can reset or limit your advertising identifier at any time in your device settings (iOS: Settings → Privacy & Security → Apple Advertising / Tracking; Android: Settings → Google → Ads).
If you purchase **Remove Ads**, interstitial ads are permanently disabled. The optional rewarded ads ("Continue" and "Undo") remain available and are only ever shown when you explicitly choose to watch them.
## Reminder notifications
The App can optionally remind you once a day to come back and play, if you turn this on in Settings. This uses your device's **local notifications** only — nothing is sent to or scheduled by a server, and no data about you is collected or transmitted. You can turn it off at any time in Settings, or by disabling notifications for the App in your device's system settings.
## In-app purchases
The App offers a single one-time purchase, **Remove Ads**. The transaction is processed entirely by Apple (App Store) or Google (Google Play). We do not receive or store your name, payment details, or billing address. Purchases can be restored on a new device via the "Restore Purchases" button in Settings.
## Children
The App is a general-audience game with no age-restricted content, no chat, and no user-generated content. Ads are always served in non-personalized mode. We do not knowingly collect personal information from anyone, including children.
## Your rights
Because the App itself does not collect personal data, most data-protection requests (access, deletion, portability) concern data processed by Google as an advertising partner — please refer to the Google links above. For anything else, contact us at aziz_ahmad@outlook.sg and we will help.
## Changes to this policy
If we change this policy (for example, when adding new features), we will update this page and the effective date above. Significant changes will be reflected in the App's store listing.
