Sudoku Time Privacy Policy

This is the English version of the Sudoku Time Privacy Policy (Korean v1.1.0). If the two versions differ, the Korean version prevails.

App information

App name: Sudoku Time (스도쿠타임) Developer: ZZARI Google Play / App Store: coming soon (links to be added) Contact: support@zzari.co

Article 1 (Purpose)

This Privacy Policy sets out how ZZARI (developer: Chunchu Kim; the "Company" or "Developer") collects, uses, provides and protects personal information in the sudoku game app "Sudoku Time" (the "App"), distributed through Google Play and the App Store.

Article 2 (Your game stays on your device)

Sudoku Time has no servers, no sign-up and no login.

The following information saved by the App is stored only on your device and is never sent outside it, including to the Company.

• One game in progress: the puzzle board and the numbers you entered, the solution, the cells given at the start, the difficulty and the elapsed time

The Company does not collect this information and has no way to access it. The saved game is deleted when you complete the puzzle, and everything is removed from your device when you delete the App.

Article 3 (Personal information collected and how)

1. Collected automatically (ads)

• Advertising data (Google AdMob): advertising identifier (Android advertising ID; on iOS, the IDFA only if you allow app tracking), device information (model, OS, app version), IP address, and ad impression and click information
• Ad consent status: whether users in the European Economic Area (EEA), the UK and Switzerland consent to personalised ads (Google's consent management tool)

The App does not use any other usage analytics, behaviour tracking or crash reporting tools.

2. Optional

• Email address (only if you email us with an inquiry)

3. How it is collected

• Automatically through the ad SDK (Google AdMob) while the App runs
• Provided directly by you when you send an inquiry email

4. Not collected

The Company does not collect:

• App usage statistics or behavioural analytics data
• Location, contacts, photos, call logs or account information
• The game data described in Article 2

Article 4 (Permissions used by the App)

The App does not request any other permissions (camera, photos, location, contacts, notifications, etc.).

Article 5 (Purposes of processing)

1. Providing ads and measuring their effectiveness
2. Responding to inquiries
3. Complying with legal obligations

Puzzle generation, rule checking and elapsed time are all handled on your device.

Article 6 (Retention and destruction)

• Information stored on your device: deleted from your device when you complete the puzzle or delete the App; starting a new game overwrites the previous one. The Company keeps no copy.
• Advertising data: handled under the service provider's (Google's) policies.
• Inquiry information: destroyed without delay within 3 years after the inquiry is resolved. Electronic files are deleted in a way that cannot be recovered.
• Where applicable law requires retention, it is kept for the required period and then destroyed.

Article 7 (Provision to third parties and outsourcing)

1. Provision to third parties

As a rule, the Company does not provide personal information to third parties without your consent. Your game data is never sent outside your device.

2. Outside services

The Company uses the following outside service to provide ads. It may process data outside Korea (e.g. in the United States).

• Google LLC: providing ads (AdMob) and managing ad consent — Google Privacy Policy

3. When the App communicates outside the device

The App communicates outside your device in the following two cases.

• Ads: Google AdMob (paragraph 2) shows ads and processes the advertising data in Article 3(1).
• Version check: the settings screen requests a public version information file on the Company's website (https://zzari.co/apps/versions/sudokutime.json) to check for the latest version. No game data is sent. As with any internet request, connection information such as your IP address may be recorded in the web server's access logs.

When you tap "Rate the app", "Update", "Privacy policy", "Terms of use" or "Contact us", the app store, a web browser or a mail app opens, and any further processing follows that service's policies.

Article 7-2 (Ads and opting out of personalised ads)

Google AdMob ads appear at the bottom of the home, completion and settings screens. No ads are shown while you are solving a puzzle.

• Information collected by ad platforms is handled under each platform's privacy policy.
• On iOS, the App asks whether to allow app tracking on first launch. You can keep using the App if you decline, and the IDFA is not collected in that case.
• Users in the EEA, the UK and Switzerland choose whether to consent to personalised ads on first launch, and can change this at any time in the App's Settings → "Ad privacy settings".
• You can reset your advertising ID or turn off personalised ads in your device settings.
  • Android: Settings → Google → Ads
  • iOS: Settings → Privacy & Security → Tracking

Article 8 (Children under 14)

The App is a puzzle game for everyone and is not primarily directed at children. The Company does not ask for or collect users' ages, and advertising data is handled as described in Article 7-2.

Article 9 (Your rights and how to exercise them)

You may at any time request access to, correction, deletion or suspension of processing of your personal information by contacting us below.

Your game data is stored only on your device, so deleting the App removes all of it.

Article 10 (Security measures)

• Administrative: a designated privacy officer and internal policies
• Technical: HTTPS communication and the principle of least privilege
• Physical: game data is processed only on your device and never sent outside it
