Go School: Baduk Problems — Privacy Policy

Last updated: 12 September 2025

Quick summary for users of our Go apps
The app collects IP address and an anonymized device ID to fix bugs and protect against hacking/fraud. These are not linked to your identity.
If you sign in, we also collect your first name and email address. Your first name may appear on leaderboards and friend invites. You can change it to an alias in Account → Profile → Edit. Your email may be used for essential account notices.
Your privacy matters to us. This policy explains what we collect, why, and how we use and share your information.

We at Go School / İstanbul Go Okulu (“Go School“, “we“, “our” or “us“) respect your privacy. This Privacy Policy describes how we handle information when you use our websites and applications, including Go School: Baduk Problems and gookulu.com (together, the “Services”). By using the Services, you agree to this Policy.

We focus on three principles:

Collect only what’s useful to provide and improve the Services.
Be transparent about the data we hold.
Build with privacy in mind by design and by default.

1) Information We Collect

1.1 Usage and Security Data (not linked to identity)

IP address
Anonymized device identifier (e.g., a random app-instance ID)

Purpose: diagnosing crashes and bugs, preventing abuse (hacking, fraud, spam), keeping the Services secure.

1.2 Account Data (only if you sign in)

First name (displayed on leaderboards/invites; you can set an alias)
Email address (for essential notices, account security, and support)

1.3 Optional Data You Share

Profile details you choose to provide (e.g., avatar), messages you send us, support requests, feedback, problem submissions.

We do not collect sensitive categories of data.

2) Cookies and Similar Technologies

We use cookies/local storage to operate sign‑in sessions, remember preferences, and understand basic usage (e.g., pages visited). If you block cookies, some features (like sign‑in) may not work.

We may use privacy‑focused analytics (for example, IP‑masked, aggregated event metrics) to understand overall usage and improve the app. Where third‑party analytics (e.g., Google Analytics) are used, they set their own cookies. See their policies for details. You can adjust your cookie settings in your browser at any time.

We do not sell your personal data.

3) How We Use Information

We use information to:

provide and secure the Services (authentication, fraud prevention, abuse detection),
fix bugs, diagnose crashes, and improve performance/features,
show names/aliases on leaderboards and social features,
send essential messages about your account, purchases, or policy changes,
comply with legal obligations.

We may create aggregated/de‑identified statistics (which do not identify you) to improve the Services. We may use and share such aggregated data without restriction.

4) When We Share Information

We share data only as needed to operate the Services or when required by law:

Service providers (e.g., hosting, analytics, email delivery, payment processing) under contracts requiring confidentiality and use limited to our instructions.
Legal/Compliance: if required by applicable law, court order, or to protect our rights, users, or the security of the Services.
Business transfers: in connection with a merger, acquisition, or asset transfer, subject to this Policy continuing or successor providing equivalent protection.

We do not disclose personal data to third parties for their own direct marketing without your explicit consent.

5) International Transfers

Our servers or providers may be located in different countries. Where data is transferred internationally, we take appropriate safeguards consistent with applicable law (e.g., contractual protections). By using the Services, you understand your information may be processed outside your country.

6) Data Security

We use administrative, technical, and physical safeguards appropriate to the nature of the data, including encrypted transport (HTTPS), access controls, and monitoring. No method of transmission or storage is 100% secure, but we continuously improve our protections.

7) Data Retention

We keep personal data only as long as necessary for the purposes described here, to comply with legal obligations, or to resolve disputes. Usage logs are retained for limited periods unless needed for security or investigations.

8) Your Rights and Choices

Depending on your location (e.g., KVKK in Türkiye, GDPR in the EU/EEA/UK), you may have rights to access, correct, delete, object to or restrict processing, and data portability.

Profile/alias: change your display name in Account → Profile → Edit.
Access/Deletion requests: contact us at iletisim@gookulu.com from your registered email; we may need to verify your identity.
Email choices: essential emails are necessary for the service; marketing emails (if any) include an unsubscribe link.
Cookies: manage via your browser settings.

If you believe your privacy rights have been infringed, you may contact the Turkish Data Protection Authority (KVKK) or your local supervisory authority.

9) Children’s Privacy

Our Services are not directed to children under 13. We do not knowingly collect personal data from children under 13. If you believe a child under 13 has provided personal data, please contact us at iletisim@gookulu.com and we will delete it promptly.

10) Community and Public Areas

If you use community features (e.g., forums, chat, leaderboards), your username/alias may be visible to others. Do not share personal information in public areas.

11) Third‑Party Links and Ads

The Services may link to third‑party sites or show third‑party content. Their data practices are governed by their own policies. If we show ads, we aim to minimize personal data sharing; any third‑party cookies/beacons are subject to the third party’s policies.

12) Changes to This Policy

We may update this Policy from time to time. We will post updates here and adjust the “Last updated” date. If changes are material, we will provide additional notice (e.g., in‑app message). Your continued use of the Services after changes become effective means you accept the updated Policy.
