Terms of Use

Last updated: 31 August 2026

These terms govern your use of Balloon Journey Japan (the “Game”), published by UNVELL Inc. (“we”). By downloading or launching the Game you agree to them.

1. Licence

We grant you a personal, non-transferable, non-exclusive licence to use the Game for your own non-commercial entertainment. We retain ownership of the Game and everything in it.

2. An online, server-run game

Your balloon is simulated on our servers so that it keeps flying while the app is closed. The Game therefore needs an internet connection to check in, and the state held on our servers is the authoritative one. We may update, suspend or modify the service, and we will give reasonable notice on this site before any planned discontinuation.

3. Transfer codes instead of accounts

There is no account and no password. Moving your balloon to another device uses a short transfer code the Game issues. Anyone who has that code can claim the balloon, so keep it to yourself. We cannot identify you without it, which means we cannot recover a balloon whose code has been lost or given away.

4. Purchases

Any purchases are processed by Apple or Google under their terms, and are tied to the store account you bought them with. Purchasable content is cosmetic — appearance and presentation. Refunds are handled by the store, according to that store’s policy.

5. What you agree not to do

• Reverse engineer, decompile, modify or redistribute the Game.
• Tamper with the messages between the Game and our servers, or otherwise falsify position, progress or records.
• Automate play, or run more balloons than the Game itself offers you.
• Sell, trade or transfer a balloon or a transfer code for money.
• Use the Game or this site to disrupt the service or other players.

Where we find such conduct we may reset the affected records or end access to the service for the balloon involved.

6. Availability

The Game is provided “as is”. We do not warrant that it will be uninterrupted or error-free, and to the extent permitted by law we disclaim implied warranties of merchantability, fitness for a particular purpose and non-infringement.

7. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental or consequential loss arising from the use of, or inability to use, the Game.

8. Age

The age rating shown on the App Store and Google Play applies.

9. Store terms

Where the standard end user licence agreement of Apple or Google applies and conflicts with these terms in respect of the Game, that agreement prevails.

10. Governing law

These terms are governed by and construed under the laws of Japan.

11. Changes

We may change these terms. Where a change is significant we will say so on this page and in the Game.

12. Contact
