Privacy Policy — Shih Tzudoku

Updated on November 7, 2026.

1. Who we are

Shih Tzudoku is a logic puzzle game for phones, published by Tatubola Games (“we”). This policy explains which data the game handles, why, who it is shared with, and how you control it.

Contact for any privacy matter: contato@tatubolagames.com.

2. Summary

  • We do not ask for your name, phone number or precise location. If you link an Apple or Google account (optional), we receive its identifier and e-mail, only so you can sign in.
  • The game creates an anonymous account, with only a random identifier, to keep your progress and take part in the ranking.
  • Your nickname, avatar and score are shown to other players in the ranking. Do not use your real name.
  • We measure how the game is used and when it crashes, anonymously, and you can turn that off in Settings.
  • We may show ads. Where the law requires it, only after your consent.
  • You can delete your account and its data inside the game at any time.

3. Data we handle

1. Anonymous account identifier

On the first launch the game creates an anonymous account in Firebase Authentication (Google). It is a random code, not tied to your name. If you uninstall the game, this code may be lost.

Optionally, in Settings, “Account”, you can link an Apple or Google account to your game, to get your progress back on another device. In that case Firebase Authentication receives the account identifier and the e-mail that Apple or Google provide (Apple may provide a hidden e-mail). We use it only so you can sign in to your account.

2. Game data

Kept on your device, and in the cloud (Google Cloud Firestore) linked to the identifier: solved levels and times, scores, helps used and won, the daily streak and gifts opened, ranking prizes, the catalog items you own and the game settings (language, sound, theme and others).

3. Profile and public ranking

You choose a nickname and an avatar. They are visible to other players, with your score and position, in the general and daily rankings. Pick a nickname that does not reveal who you are.

4. Game usage (Google Analytics for Firebase)

Events such as starting and finishing a level (with its size, difficulty, time and points), using a help, finishing the daily challenge, losing a streak and watching a rewarded video. Google also collects technical device data (model, system, language, approximate country from the IP address). This is tied to the anonymous identifier, never to a name or e-mail.

5. Crash reports (Firebase Crashlytics)

When the game crashes, we receive the type of error, the state of the app, the device model and system, and the anonymous identifier, so we can fix the problem.

6. Ads (Google AdMob)

The game may show full-screen ads between levels and videos you choose to watch to earn a help. For that, Google and its ad partners may handle the device advertising identifier (if you allow it), the IP address (from which they may estimate the approximate location) and device data, to choose and measure ads and prevent fraud. Where required (European Economic Area, United Kingdom and Switzerland) we show a consent form before requesting any ad. On iPhone, the system asks whether you allow apps to track you.

7. Remote configuration (Firebase Remote Config)

The game asks the server, for example, whether ads are on. This request uses Firebase installation identifiers.

8. Premium purchase (RevenueCat, App Store and Google Play)

The game sells one optional, one-time purchase, the Premium (no ads and helps that renew every day). Payment is made directly on the App Store or Google Play, which charge you and tell us only whether the purchase was made. We use RevenueCat, Inc. to verify the purchase: it receives the anonymous account identifier, the purchase history of the game and technical device data, so the Premium comes back after you reinstall the game or change device.

9. Reminders (notifications on the device)

If you allow it, the game schedules notices on the device itself about the daily challenge, the streak and the ranking, at most one in the morning and one in the evening. They are made and shown by the device and send no data to us. To choose the time, the game reads the time zone of the device. You turn them off in Settings, “Reminders”, or in the system settings.

10. Catalog images

If the catalog has an image for an avatar, a frame or a gift, the game downloads it from a server and keeps it on the device. As with any internet access, the server receives the IP address of the connection; we do not tie this to you.

What we do not collect

Name, phone, address, precise location, contacts, photos, microphone and camera. The e-mail only reaches us if you link an account. We also do not see or keep card numbers or other payment data: the App Store or Google Play handle them.

  • Making the game work (account, progress, ranking, prizes): performing the service you asked for by installing the game.
  • Understanding usage and fixing errors (analytics and crashes): our legitimate interest in improving the game, and your consent where the law requires it. You can turn it off in Settings, “Help improve the game”.
  • Showing ads: your consent where the law requires it, and our legitimate interest in keeping the game free.
  • Selling and verifying the Premium: performing the purchase contract you made.
  • Security and fraud prevention in the ranking and prizes: legitimate interest.
  • Reminders (notices on the device): your consent, given through the system notification permission.

5. Who we share it with

We use Google LLC as processor for the Firebase services (Authentication, Cloud Firestore, Cloud Functions, Remote Config, Analytics and Crashlytics), for Google AdMob (which may involve ad partners), and RevenueCat, Inc. to verify the Premium purchase. If you link an account, Apple or Google handle the sign-in. Your nickname, avatar and score are public to other players. We do not sell your data.

Google servers may be outside your country. These transfers rely on the safeguards of applicable law, such as the Brazilian LGPD and, where it applies, the GDPR.

6. How long we keep it

Account data stays while the account exists. When you delete the account, we remove the game data, the profile and the ranking entries tied to the identifier. Analytics data is kept for the limited period set in Google Analytics (at most 14 months) and crash reports for the Crashlytics period. Google backups may take some time to clear.

7. Your rights and how to use them

You may ask for access, correction, deletion, portability, information about sharing, objection to processing and withdrawal of consent (Brazilian LGPD, the GDPR and similar laws).

  • Delete the account and data: in the game, Settings, “Delete account”. It erases the identifier and the progress and creates a new identifier.
  • Turn off analytics and crash reports: Settings, “Help improve the game”.
  • Change your ad consent: Settings, “Privacy options” (shown where the law requires it).
  • Tracking on iPhone: iPhone Settings, Privacy & Security, Tracking.
  • Advertising identifier: in the privacy settings of your device.
  • Getting the Premium back: in the game, Settings, Premium, “Restore purchases”. Refunds are requested from the App Store or Google Play.
  • If you cannot use the game, write to contato@tatubolagames.com with your player code (Settings) and we will handle the request.
  • Turn off reminders: Settings, “Reminders”, or the notification settings of the device.

You may also complain to the Brazilian data protection authority (ANPD) or to the authority of your country.

8. Children

Shih Tzudoku is not directed at children under 13 and we do not ask anyone’s age. If you believe a child gave us data improperly, write to contato@tatubolagames.com and we will delete it.

9. Security

Data travels over encrypted connections and is kept in Google services, with access rules that let each player read and write only their own data. No system is completely secure, and we cannot guarantee absolute protection.

10. Changes to this policy

We may update this policy. The update date is at the top of this page, and relevant changes will be announced in the game.
