Privacy policy

1. Information collected

We may collect names, phonetic name readings, company names, email addresses, phone numbers, inquiry details, account identifiers, nicknames, gender, age groups, self-reported skill levels, selected avatars, learning history, ranks and badges, game and operation history, device and browser information, IP addresses, cookies and other usage information.

Nicknames and avatars may be visible to other users. Gender, age group and self-reported skill are not made public.

2. Purposes of use

Information is used to provide the Service, verify identity, manage membership and learning records, operate friend games, answer inquiries, improve quality, investigate defects, prevent misuse, send important notices, analyze usage and meet legal requirements.

3. Analytics

To improve the Service, we collect events such as starting a lesson, first completion, registering a member profile, starting a game, sharing and viewing Premium information. Analytics events do not include names, email addresses, member IDs, room codes or passcodes. Page URL queries and invitation information are removed before transmission.

Before registration, learning records are stored in the same browser for seven days after the last use. If you choose to save them when registering or signing in, they are carried over to your member account. The date of the first visit stored in the browser is used to identify continued use. Clearing browser data removes pre-registration records and the information used to recognize return visits.

The Service uses Google Analytics 4 to collect browsing information through cookies and similar technologies. Collected data is managed under Google’s terms and privacy policy. Collection can be limited through browser settings or the Google Analytics Opt-out Browser Add-on.

4. Third-party disclosure, outsourcing and business succession

The Company does not provide personal data to third parties except with the individual’s consent, when entrusting necessary handling to service providers, in a business succession, or as required by law. Service providers are appropriately selected and supervised.

If the business relating to the Service is succeeded through a merger, company split, business transfer or other event, the Company may transfer relevant user information to the successor. The successor will handle it within the purposes identified before the succession.

5. Security

We implement reasonable security measures, including access controls, authentication and protection of communications, to prevent leakage, loss, damage, unauthorized access and similar risks.

6. Disclosure, correction, deletion and other requests

Requests for notification of purposes of use, disclosure, correction, addition, deletion, suspension of use, erasure or cessation of third-party provision of retained personal data are handled in accordance with law after identity verification.
