If the App is distributed through another authorized app store, enterprise distribution channel, testing channel, or direct distribution method, your use of the Services may also be subject to the terms and rules applicable to that channel.

You agree to comply with all applicable platform terms and policies. If platform rules impose stricter requirements for purchases, subscriptions, digital goods, NFT-related functionality, wallet interactions, external links, or user disclosures, those requirements apply to the affected version or distribution channel of the App.

23. Changes to these Terms

We may update or modify these Terms from time to time.

If we make material changes, we may provide notice through the App, our website, the applicable app store listing, email, or other reasonable means. The updated Terms will be effective as of the date stated at the top of the document unless otherwise specified.

24. Governing Law

These Terms will be governed by and construed in accordance with the laws of Republic of Korea, without regard to conflict of law principles.
