This is a translation of the Korean policy. If the two versions differ, the Korean version prevails.
1. Scope
This policy applies to the content on mariago.kr and to the MariaGO game subdomains linked from those pages. Once you move to an external site, its own policy governs how your information is handled.
2. Information that may be processed
The main pages do not require sign-up and have no input fields that directly collect your name, phone number or address. The connected games may store values such as a random identifier, the model you selected and the code of a game in progress in your browser storage, to let you continue games and keep your settings.
To save games, the Go service keeps a random guest identifier and access key, the board state, the move order, the number of captured stones and the time each game was created and updated on the server. These values are used for reviewing games and continuing after reconnecting, and are not used to verify anyone's real identity.
For security and troubleshooting, the web server may temporarily keep ordinary access logs that include the access time, requested address, browser type and IP address.
3. Purpose of use
- Saving game progress and providing record viewing and continuing games
- Keeping the screen and AI model settings you selected
- Blocking abnormal requests, analysing service failures and improving stability
- Improving content and features based on anonymised usage flows
4. Retention and deletion
Data stored in your browser is removed from that device when you delete the site data or local storage in your browser. In that case the access keys for saved games are also lost, and you may not be able to open earlier game records again.
Game records and access logs on the server are kept for as long as needed to run the service and investigate errors, and are cleaned up once that purpose is gone. Where the law requires retention, we follow the required period.
6. Ads and external services
Google AdSense ads are shown on MariaGO's dev log posts, About page and Go research notes. Ad providers may use cookies or similar identification technologies to show ads, limit frequency, prevent abuse and measure performance. Third-party ad vendors, including Google, may serve ads based on your previous visits.
You can review and manage personalised ad settings and how ad data is used at Google My Ad Center and in Google's advertising policies.
7. Your choices and changes to this policy
You can limit cookies and site data in your browser settings or delete information that has already been stored. If you block storage, some features such as continuing games, the record list and settings may not work properly.
When features or external services change, we update this document to match how things actually work and renew the effective date below. Important changes are announced separately on the main site.
Effective date: October 4, 2026
5. Dev log comments
When you comment on a dev log (/devlog) post, the information below is collected, and the comment is posted only if the author has agreed to its collection and use.
The email address and IP address are never shown on screen and are stored only in the server database. New comments do not ask for a password. Comments left with a password before Google sign-in can still be edited or deleted only with that password. Private comments can be seen only by the author and the admin.
Authors can edit or delete their comments with the same Google account, and deleting a comment also deletes the information collected with it. If you have forgotten the password of an older comment, please contact us on the Q&A board. Comments that defame others or contain personal information may be removed without notice.
