Blastoku: Block Combo Blast
Privacy Policy
Effective November 6, 2026
Blastoku: Block Combo Blast (Android, package com.kausarstudio.blastoku)
Developer: Kausar Studio · Contact: support@kausarstudio.com
In short: the game has no accounts, and we (Kausar Studio) do not collect, receive or sell any of your personal data. Your game progress stays on your device. To show ads, the game uses Google AdMob, which collects some device and usage data as described below. Where the law requires it, you are asked for consent first, and you can change your choice at any time from the game's Settings.
1. Who we are
Blastoku is made by Kausar Studio, an independent developer. Questions about this policy: support@kausarstudio.com.
2. Information the game stores on your device
The game saves the following only on your device, so you can continue where you left off:
- Game progress: the Classic run in progress and today's daily board in progress (board, pieces, score and combo), saved after every move; your best score; and the score of the last daily board you finished.
- Settings: your Sound, Music, Vibration and Reduce motion choices, the block colours you picked, and how many of the 3 ads toward the Neon block colours you have watched.
- Ad counters: how many matches ended since the last full-screen ad, when the last full-screen ad closed, how many were shown in the current session, how many reward ads you watched today, and when an ad-free pass ends. They are used only to space ads out and to keep the daily limits.
This information never leaves your device through the game and is not sent to us. The game also keeps it out of Android's cloud backup, so it is not copied to your Google account. On Android 12 and newer, a direct device-to-device transfer when you set up a new phone can still carry it over. Uninstalling the game, or clearing its storage in Android Settings, deletes this data.
3. Sharing your score
When you tap Share after a run, the game draws a score card image with your score and your best score on your device and opens Android's share sheet. Nothing is sent unless you pick an app to share with; what you share then goes to that app and the people you choose, under their own policies. We never receive it.
4. Advertising (Google AdMob)
The game shows ads provided by Google AdMob (Google LLC). No ad appears on the game screen while you place pieces, and no full-screen ad appears on the Pause screen unless you ask for one:
- A full-screen ad between matches, when you tap Play again or Home after a game over: at most once every 3 matches, at least 2 minutes after any other full-screen ad, never in the first 2 minutes after you open the game, and at most 6 times per session. A short "Ad break" notice appears first, so the ad never opens under your tap.
- Optional rewarded ads, each named before the ad plays, and you never have to watch one:
- Continue: 3 small pieces that fit when no space is left, once per run.
- Shuffle: a new set of 3 pieces, up to twice per run.
- Undo: takes back your last move, once per run.
- No ad breaks for 15 min: from the Pause screen, after you have seen an ad break; for 15 minutes no full-screen ad appears between matches (ad cards stay).
- Neon block colours: 3 ads, one at a time ("Ad 1 of 3"); your progress is kept. A best score of 5,000 unlocks them without ads. Each reward can be earned at most 5 times a day.
- An ad card marked "Ad" (a "native" ad) on the Home screen and on the game over screen.
To serve and measure ads, Google's Mobile Ads SDK automatically collects and shares with Google the following data:
| Data | What it is | Why |
|---|---|---|
| Approximate location | Your device's IP address, which can be used to estimate a general location | Advertising, analytics, fraud prevention |
| Device or other identifiers | Android advertising ID, app set ID and, where applicable, identifiers related to accounts signed in on the device | Advertising, analytics, fraud prevention |
| App interactions | Interactions such as app launches, taps and ad views | Advertising, analytics, fraud prevention |
| Diagnostics | Performance information such as crash logs, app launch time and hang rate | Analytics, fraud prevention |
This data is encrypted in transit (TLS) and is processed by Google, not by us. Ads are limited to content suitable for general audiences with parental guidance (rating PG) or below. Learn how Google uses this information: How Google uses information from sites or apps that use its services and the Google Privacy Policy.
5. Permissions
The game asks for no permission that shows a prompt. The Google Mobile Ads SDK adds these, all used only for ads:
| Permission | Why |
|---|---|
| Internet, network state | Load ads; the game itself needs no connection |
Advertising ID (AD_ID) and Android's ad services (ad ID, attribution, topics) |
Advertising and ad measurement, as described above |
| Wake lock, foreground service | Background tasks of the ads SDK (through Android's WorkManager) |
The game itself uses the network only through these ads and when you open a link.
6. Your consent (EEA, United Kingdom and Switzerland)
If you are in a region where consent is required, a consent message from Google's User Messaging Platform appears when you first open the game, before any ad is requested. You can accept, decline or manage your choices. You can change your decision at any time: open the game, go to Settings and tap Privacy options (shown in the regions where it applies). Your consent choice is stored on your device.
7. Your choices
- Read this policy: tap Settings > Privacy policy in the game; it opens this page in your browser. Offline, the game shows its address so you can open it later.
- Advertising ID: you can reset or delete your advertising ID in Android Settings (Privacy > Ads, or Google > Ads, depending on your device).
- Personalized ads: where consent applies, use Privacy options in the game's Settings. You can also manage ad settings at My Ad Center.
- Play offline: the game is fully playable without an internet connection; no ads are loaded while you are offline, so rewarded offers are not shown then.
- Delete your data: uninstall the game or clear its storage to remove all data kept on your device. For data held by Google, use Google's tools linked above.
8. Children
Blastoku is intended for players aged 13 and over and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the game, contact us and we will help remove it.
9. Data retention, deletion, sharing and security
We do not keep, sell or share any personal data, because the game does not send personal data to us. The data on your device stays until you uninstall the game or clear its storage. Data collected by Google AdMob is kept, deleted and protected by Google under its policies, on Google's servers, which may be outside your country. The game itself does not use analytics, does not have accounts and does not offer in-app purchases.
10. Your rights
Depending on where you live (for example under the GDPR, the UK GDPR, Indonesia's Personal Data Protection Law (UU PDP), or US state privacy laws such as the CCPA/CPRA), you may have rights to access, correct, delete or object to the processing of your personal data, and to opt out of personalized advertising. Because we do not hold your personal data, these requests are handled through the choices above and through Google for advertising data. You are welcome to contact us with any question.
11. Changes to this policy
We may update this policy, for example when the game adds new features. The effective date at the top shows the latest version. Significant changes will also be mentioned in the game's update notes.
