Terms of Service — Echo Cave

By loading or playing Echo Cave, you confirm you have read and agree to these Terms of Service. If you do not agree, please do not use the game.

1. Introduction

Welcome to Echo Cave. These Terms of Service (“Terms”) govern your use of the game and its associated pages. We have kept them concise and proportionate to a free, no-registration game.

2. The game

Echo Cave is a non-violent, family-friendly arcade game in which players navigate a sound wave through a fictional resonant cave system collecting harmonic crystals. The game is provided entirely free of charge with no account or payment required.

Echo Cave is a work of sonic fiction. The acoustics, cave physics, and crystal mechanics depicted are fanciful and not scientifically accurate. The game is not affiliated with any geology, acoustics, or speleology institution.

3. Who can play

Echo Cave is open to all players with a web browser. No age verification is required because no personal data is collected. Parents and guardians are encouraged to exercise reasonable oversight of children’s internet use generally.

4. Permitted and prohibited use

You may play Echo Cave for personal, non-commercial enjoyment. You must not:

Use bots, scripts, macros, or any automation to play the game or alter scores
Reverse-engineer, decompile, or modify the game’s code for harmful or commercial purposes
Flood or attack our servers or network infrastructure
Use the game or its content for any commercial purpose without prior written permission
Use the game in any manner that violates applicable law or infringes the rights of others

5. Intellectual property and licence

You receive a limited, personal, non-exclusive, non-transferable, revocable licence to play the game for private enjoyment only. No other rights are granted.

Echo Cave's sound wave character is a creative abstraction of acoustic physics. The game is not intended as an educational resource for real sound science or cave exploration.

6. Fair play

Echo Cave is designed to be enjoyed honestly. Deliberately exploiting bugs or unintended mechanics to achieve results not available through normal play is prohibited and may result in restricted access.

7. Availability

We provide Echo Cave on an “as is” and “as available” basis without guarantees of uptime or error-free operation. We reserve the right to update, modify, suspend, or discontinue the game at any time without notice.

8. No warranties

To the fullest extent permitted by law we disclaim all warranties — express or implied — including merchantability, fitness for a particular purpose, and non-infringement. Use of the game is entirely at your own risk.

9. Limitation of liability

To the maximum extent permitted by applicable law we are not liable for any direct, indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use Echo Cave. Because the game is free our maximum aggregate liability to you is zero.

10. External links

11. Governing law

These Terms are governed by applicable law. Disputes arising from your use of Echo Cave are subject to the jurisdiction of competent courts, except where mandatory consumer protection law in your jurisdiction provides otherwise.

12. Changes to these Terms

We may revise these Terms at any time. The effective date at the top of this page indicates when the current version applies. Continued use of the game after a revision constitutes acceptance.
