Privacy Policy for Sudoku Pentathlon

Last updated: July 31, 2026

This Privacy Policy describes how Sudoku Pentathlon (the “App”), Android package com.noyly.sudoku_pentathlon, published by Noyly Games and operated by Noyly (노일리, the “Developer,” “we,” “us,” or “our”), collects, uses, and protects information when you use our mobile Sudoku game on Android (and other platforms where the App is offered).

1. Summary

The App is offered to users aged 13 and older on Google Play. It does not require you to register with your name, email, or phone number to play. Most game progress is stored on your device. If you choose optional Google Sign-In, we store a display nickname, gameplay progress (including XP, achievements, and statistics), and daily ranking data in the cloud. We do not sign you in automatically when you open the App; sign-in runs only when you choose it. Third-party services (Google AdMob, Firebase, Google Play Billing) may process additional technical or purchase-related data as described below.

Cloud features (sign-in, leaderboard, purchases): You must be at least 13; ages 13–17 need parental/guardian consent; ages 18+ may proceed on their own. Before using these features, the App shows an in-app notice; tapping confirm means you attest that any required consent has been obtained (Section 11).

2. Information We Collect

2.1 Data stored on your device (local)

This data stays on your device unless you use cloud features below or uninstall the App (which removes local app data).

2.2 Optional Google Sign-In and cloud data

If you sign in with Google, we may process and store in Firebase (Firestore):

Cloud sync runs only while you are signed in. Guest play remains on your device unless you choose to sign in.

Google may provide account information according to your Google account settings and Google’s Privacy Policy.

2.3 Automatically collected data (third-party SDKs)

The App uses third-party SDKs that may collect data such as:

2.4 In-app purchases (Google Play)

Purchases are processed entirely by Google Play. We receive only what Google provides to the App (such as product ID, purchase state, and subscription renewal status) to unlock ad-free features. We do not store payment card numbers. Refunds and subscription management follow Google Play policies.

3. How We Use Information

4. Legal Basis (EEA/UK users)

Where applicable, we rely on:

5. Data Sharing

We do not sell your personal information. Data may be processed by service providers under their own policies, including:

We may disclose information if required by law or to protect our rights and users.

6. Data Retention

7. Data Security

Data transmitted between the App and our cloud or third-party services is protected using industry-standard HTTPS/TLS encryption. No method of storage or transmission is 100% secure; we work to protect your information using reasonable safeguards.

8. Your Choices and Rights

Depending on your region, you may have rights to access, delete, or object to certain processing. Contact us using the email below.

Consent revoke / change link (EEA, UK):

https://noyly.com/privacy-policy.html#advertising-and-consent

If you are in the European Economic Area, the United Kingdom, Switzerland, or another region where consent is required for advertising, you can change or withdraw your choices for ads in the App at any time. The App uses Google’s User Messaging Platform (UMP). In eligible regions you may see options such as Consent, Do not consent, and Manage options, depending on your location and AdMob settings. Withdrawing consent for personalized or non-personalized ads may mean fewer or no ads, and ad-based hints or Expert unlock may not be available.

In the App (recommended):

  1. Open Settings (gear icon on the main screen)
  2. Tap Ad privacy choices (or the equivalent label in your language)
  3. Update your preferences in the Google consent screen (accept, reject, or allow non-personalized ads only, depending on options shown)

On your device (Google):

If the in-app consent screen does not open (e.g., you purchased ad removal), use the device links above or email us at support.pentathlon@gmail.com with subject Ad consent / privacy.

9. Account Deletion (in the App)

Delete account in Settings: When signed in with Google, open Settings → Delete account. You must confirm by typing your in-game nickname, acknowledge that all data will be permanently deleted, and re-authenticate with Google. Upon successful deletion:

  • Your Firebase Authentication account is removed
  • Your Firestore profile (including cloud progress), private sync metadata, and daily ranking entries tied to your account are deleted from our servers
  • Local app data on your device may remain until you clear storage or uninstall

11. Children’s Privacy and Minors (Ages 13–17)

Children’s Privacy: Our service is not intended for children under 13. If you are under 13, please do not use our service.

11.1 Users under 13

Sudoku Pentathlon is listed on Google Play for audiences 13 years of age and older. The App is not directed to children under 13, and we do not knowingly collect personal information from anyone under 13.

If you are a parent or guardian and believe your child under 13 has used the App or provided personal information, contact us at support.pentathlon@gmail.com. We will take steps to delete that information promptly.

11.2 Cloud features — age and in-app notice

Before you use cloud features (Google Sign-In, global leaderboard, cloud progress sync, or in-app purchases/subscriptions), the App displays a notice. You may proceed only if you are at least 13 years old. If you are 13 to 17, you must have obtained parental or legal guardian consent for personal data processing. If you are 18 or older, you may proceed on your own.

When you tap the confirmation button in that notice, you represent that:

We do not separately verify parental identity on each use; the notice is how we inform users and record their attestation before cloud processing begins. Parents and guardians remain responsible for supervising use of the App by minors in their care.

Cloud features covered by this notice include:

In-app notice (English, as shown in the App):

“To use cloud features (leaderboard, purchases), you must be at least 13. If you are 13–17, you need consent from a parent or legal guardian. If you are 18 or older, you may proceed on your own. By continuing, you confirm any required consent has been obtained.” — Confirm: “Continue (I have parental consent)”.

In-app notice (Korean):

“클라우드 기능(리더보드, 구매)을 사용하려면 만 13세 이상이어야 합니다. 13~17세는 보호자 동의가 필요합니다. 18세 이상은 본인이 진행할 수 있습니다. 계속하면 필요한 동의를 받았음을 확인합니다.” — 확인: “계속 (보호자 동의 완료)”.

Parents and guardians may:

We encourage families to review Google Family Link and device-level ad and account controls.

11.3 General age representation

12. International Transfers

Google and Firebase may process data in countries other than your own, including the United States, under appropriate safeguards described in their policies.
