Privacy Policy

AI Taekwondo Co., Ltd. (the “Company”) provides the easy tedu service (the website and the dojang screen apps, the “Service”) and treats your personal information with care. This policy explains what information we process and why, how long we keep it, and what rights you have.

1. Why we process personal information

We process personal information only for the purposes below. If a purpose changes, we will tell you in advance and ask for your consent.

• Signing up and verifying who you are, managing your account, and managing dojang membership and permissions
• Registering dojang screens (TVs, tablets), controlling them remotely, and playing class videos
• Receiving and answering inquiries and consultation requests
• Keeping the Service stable — preventing misuse, finding the cause of failures, and improving performance
• Providing class history (so a dojang can see its own class times)

2. What we collect

The users of the Service are dojang operators (masters and instructors). We do not register individual trainees or collect trainees’ personal information.

A. Information you enter

B. Information created automatically while you use the Service

C. Camera and microphone

We access the camera and microphone only when you use ‘Live view’ or ‘Share My Camera’. If you don’t use these features, we don’t access them.

• Video and audio travel directly between devices. When a direct connection isn’t possible because of the network, they pass through a relay server operated by the Company.
• In no case does the Company record or store video or audio. We keep only figures used to check connection quality (resolution, frames per second, latency, etc.), and these contain no video or audio.
• To find a connection path between devices, a public STUN server operated by Google may be used as a backup, and your IP address may be sent to that server.

3. How long we keep it

Where another law requires us to keep information, we follow that period. If you use a paid service, under Korea’s Act on the Consumer Protection in Electronic Commerce we keep contract and withdrawal records for 5 years, payment records for 5 years, and consumer complaint and dispute records for 3 years.

4. Sharing with third parties

We do not provide your personal information to third parties, except when you have agreed in advance, or when an investigative agency or other authority requests it through a lawful procedure.

5. Service providers and international transfers

We entrust the tasks below to outside providers to run the Service. All of them are located outside Korea.

You may refuse these international transfers. However, push notifications and emails are essential to the Service, so if you refuse, you won’t be able to use some features such as signing up and remote launch. Please tell us through the contact in Section 8.

6. Destruction

When the retention period ends or the purpose is fulfilled, we destroy the information without delay. Electronic files are deleted in a way that cannot be recovered, and any printouts are shredded or incinerated. Access and performance logs are deleted automatically after the periods in Section 3.

7. Your rights and how to use them

You may at any time:

• View your personal information or ask for a copy
• Ask us to correct wrong information
• Ask us to delete it (except where a law requires us to keep it)
• Ask us to stop processing it

You can check and change most account information yourself on the Settings screen of the Service, and you can delete your account there too. For anything else, contact us through Section 8 and we will handle it without delay.

We do not collect personal information from children under 14. Only dojang operators can create accounts.

8. Privacy officer

9. How we keep information safe

• Passwords are stored encrypted in a way that cannot be reversed.
• All communication is encrypted (HTTPS).
• We keep only an irreversibly transformed value instead of the original IP address.
• Access to systems that handle personal information is limited to the minimum staff needed.
• We keep access records so that misuse can be checked.

10. Cookies

We use cookies to keep you signed in and to remember your language. On the website, the analytics tool in Section 5 may also use cookies to improve screens. You can refuse cookies in your browser settings, but then you may not stay signed in and some features may be hard to use.

11. Where to get help

If you need advice or help about a privacy violation, you can contact the Korean agencies below.
