Terms of Service

Last updated: 2026-05-08

These terms describe how HexWave is offered. They are written in plain language and kept short on purpose. If anything below is unclear, see Contact.

1. Acceptance of Terms

By creating an account or using HexWave at https://hexwave.app, you agree to these terms. If you do not agree, please do not use the service.

2. The Service

HexWave is an I Ching reading product. It calculates a Birth Hexagram triad from your birth date using the Plum Blossom method, surfaces a daily hexagram, and offers Mutual Hex Maps and Bond Levels between people you add. The reading interpretations are synthesized by a language model driven by our proprietary calculation frameworks and curated prompts, and are then cached. We provide the service as is, without warranty of any specific outcome. The I Ching is a system of symbols; HexWave is a reading tool for educational and entertainment purposes, not a medical, legal, or financial advisor.

3. Subscriptions

HexWave Premium subscriptions, when available, will be sold through the mobile app via the Apple App Store or Google Play. Subscription terms, payment processing, taxes, and refunds are handled by Apple or Google. The free tier never expires and never requires a card. See our Refund Policy for refund terms.

4. Acceptable Use

Use HexWave for yourself and the people you connect with. Do not attempt to scrape the content library, reverse the calculation engine, abuse the LLM generation pipeline, impersonate other people, or use the service to harass anyone. We may suspend accounts that violate these constraints. HexWave is subject to fair-use limits and anti-abuse measures; we may rate-limit or temporarily restrict excessive automated requests.

5. Intellectual Property

The I Ching itself belongs to no one. The HexWave product (the calculation engine, the design, the prompt architecture, and the specific compilation of the generated interpretations) is owned by HexWave. You retain ownership of the birth data and content you provide. You grant HexWave a non-exclusive, worldwide license to process that data solely to deliver the service to you.

6. Limitation of Liability

To the fullest extent permitted by law, HexWave is provided as is. HexWave is not liable for indirect, incidental, or consequential damages. Total liability under these terms is limited to the amount you paid HexWave in the twelve months preceding the claim.

7. Governing Law

These terms are governed by the laws of the State of Israel. Disputes will be resolved in the courts of the State of Israel.

8. Changes

We may update these terms. Material changes will be announced in the app and on this page. Continued use after a change means you accept the updated terms.
