Information we handle and how it is collected

Stored only on your device (never sent to us)

The App reads the device ringer mode (normal / silent / vibrate) to decide whether to play stone sounds. The value is not stored or transmitted.

For development diagnostics, engine commands (the moves of the game) may be written temporarily to the device system log (logcat). This log never leaves the device and contains no personally identifying information.

Collected automatically by the Google ads SDK (sent to Google)

The App includes the Google Mobile Ads SDK (AdMob) for rewarded ads. Every time the App starts, the SDK initializes and preloads a rewarded ad automatically, even if you never tap “광고보기” (Watch ad). In doing so, the following is sent to Google LLC:

• Device identifiers: Android advertising ID (AAID) and, on Android 13+, the AdServices advertising ID
• IP address (from which approximate location may be inferred)
• Device and app information such as model, OS version, language, package name and version
• Ad interactions: requests, impressions, clicks, completed views
• SDK diagnostics and performance data
• On Android 13+: Privacy Sandbox interest Topics and ad attribution (measurement) data

Game records, SGF files, coin balance and tsumego data are not included in ad requests. We do not receive this information about individual users from Google.

When you contact us

Only if you email us, we receive your email address and whatever you write in the message.

What we do not process

The App does not access location (GPS), camera, microphone, contacts, photos or media files, health data or payment data, and does not process sensitive data or national identification numbers. The App uses no analytics or crash-reporting tools of its own.

Purposes of processing

• Game records / SGF: listing games in the Records tab, reviewing games, resuming unfinished games.
• Coins and daily-gift date: managing the in-app virtual coins and granting one gift per day.
• Tsumego progress: showing solved problems and mistakes.
• Data handled by the ads SDK: serving and measuring rewarded ads, fraud prevention, ad personalization (unless you turn it off), SDK diagnostics, all processed by Google.
• Support emails: answering your inquiry and fixing problems.

Retention

• On-device data stays on your device until you delete it in the Records tab, clear the App’s storage or uninstall the App. We keep no copy.
• Android Auto Backup: if Google backup is on, game records and app preferences (coins, tsumego progress) may be backed up to your own Google account (Google Drive) and restored when you reinstall or move to a new device. Google stores this backup under its policies and your backup settings; we cannot access it.
• Ads SDK data is retained by Google under the Google Privacy Policy.
• Support emails are deleted without delay once the inquiry is resolved, unless the law requires us to keep them.

Disclosure to third parties

We do not sell or provide your personal information to third parties. The only user information we hold is support email, which we disclose only when required by law through due process. The Google ads SDK sends the data described above directly to Google, as detailed in the next two sections.

Processors and third-party SDKs

We do not outsource the processing of personal information. The App contains the following external components:

International transfer

Because of the Google ads SDK, some data is transferred outside Korea (PIPA Article 28-8):

Recipient

Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (contact via the Google Privacy Policy)

Countries

United States and other countries where Google operates data centers

Data

Advertising IDs, IP address, device/app information, ad interactions, SDK diagnostics, and on Android 13+ interest topics and attribution data

When and how

Over the internet when the App starts (SDK initialization and ad preload) and when ads are requested or shown

Purpose

Ad delivery and measurement, fraud prevention, personalization, diagnostics

Retention

As set out in the Google Privacy Policy

How to refuse

Delete or reset your advertising ID and turn off ad privacy features (see “Automatic collection”). Nothing is sent while the device is offline, although the SDK may send diagnostic data it queued once a connection is available again. AI games, records and tsumego still work offline, but rewarded ads (coin rewards) are unavailable. You can also uninstall the App.

Device permissions

All permissions declared in the release build are normal (install-time) permissions. The App asks for no runtime permissions such as location, camera, microphone, contacts, storage or notifications.

Automatic collection (advertising identifiers)

The App does not use cookies. The Google ads SDK uses the advertising ID and, on Android 13+, Privacy Sandbox features (Topics and attribution). The App itself has no ad-personalization switch, but you can limit tracking in device settings (menu names vary by manufacturer and Android version):

• Delete or reset the advertising ID: Settings › Google › Ads or Settings › Privacy › Ads
• Turn off ad topics, app-suggested ads and ad measurement (Android 13+): Settings › Privacy › Ad privacy
• Manage personalized ads for your Google account: My Ad Center

If you delete your advertising ID, a string of zeros is sent instead. Ads may still appear, but they will not be personalized.

Deletion

We hold no copy of on-device data, so you delete it yourself. Deleted data cannot be recovered.

• Single game record: in the 기록실 (Records) tab, tap the trash icon next to a record. It is deleted immediately without a confirmation dialog.
• All data: Settings › Apps › AI HyoGo › Storage › Clear data, or uninstall the App. There is no in-app menu that resets coins or tsumego progress at once.
• Google backup copy: Settings › Google › Backup or the Backups section of the Google Drive app.
• Support emails: permanently deleted from our mailbox after the inquiry is resolved.

See the step-by-step account and data deletion guide.

Your rights

You may request access to, correction or deletion of, or suspension of processing of your personal information, and withdraw consent at any time. On-device data can be viewed in the App and deleted as described above. Ads data can be limited in device settings, and requests about data held by Google can be made to Google. For anything else, email [email protected]; we reply without delay and within 10 days. Because we hold no data that identifies you, we cannot view or delete data on your device on your behalf. You may also exercise your rights through a legal guardian or authorized agent.

Children

The App is a board game for teenagers and adults who enjoy Go and is not directed at children under 14. We collect no information that identifies a child. The ads SDK does not distinguish users by age, so parents should review the ad settings above on a child’s device.

A child under 14 who emails us may need a legal guardian’s consent. If we learn that we received an email from a child under 14 without guardian consent, we delete it without delay.

Security measures

• No server: we run no server that stores user records, so we cannot leak them through a server breach.
• App-private storage: records are kept in Android’s per-app sandboxed storage that other apps cannot read.
• Minimal permissions: no dangerous runtime permissions are used.
• Support email is handled only in an access-controlled mailbox and deleted after resolution.

Security of the ads SDK and of Google backups is managed by Google.
