Terms of Use (EULA)

Effective date: 25 March 2026

Crux — End User License Agreement (EULA)

This End User License Agreement ("Agreement") is between you ("User") and Matthew Chrisp ("Developer"), the creator of the Crux application ("App"). By downloading, installing, or using Crux, you agree to be bound by this Agreement. If you do not agree, do not use the App.

This Agreement supplements the standard Apple Licensed Application End User License Agreement (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). Where this Agreement conflicts with Apple's standard terms, the more restrictive provision applies.

1. License

The Developer grants you a limited, non-exclusive, non-transferable, revocable licence to use Crux on Apple devices that you own or control, in accordance with Apple's Usage Rules and this Agreement.

2. AI-Generated Content Disclaimer

Crux uses Google's Gemini AI to provide decision-coaching conversations. You acknowledge and agree that:

(a) All AI-generated responses are for informational and reflective purposes only. They do not constitute professional advice of any kind, including but not limited to legal, medical, financial, psychological, therapeutic, relationship, or career advice.

(b) The AI may produce responses that are inaccurate, incomplete, or unsuitable for your circumstances. You are solely responsible for any decisions you make based on your use of the App.

(c) The Developer does not guarantee the accuracy, reliability, or appropriateness of any AI-generated content.

(d) You should consult qualified professionals for decisions involving health, legal matters, finances, relationships, or other areas requiring professional expertise.

3. Data Processing

When you use Crux, your conversation text, decision tree data, and impact ratings are transmitted to Google's Gemini AI service for processing. Anonymous usage analytics (stage completion, timing, and decision category) are collected via Firebase Analytics. No conversation content or personal details are included. You can opt out in Profile settings. This data is subject to Google Cloud's Terms of Service and the Firebase Terms of Service. The Developer does not control how Google processes or retains API request data. Please refer to the Privacy Policy for full details.

4. In-App Purchases

(a) Crux offers consumable in-app purchases ("Decision Sessions") processed entirely by Apple. The Developer does not collect or store your payment information.

(b) Consumable purchases are non-refundable once the session has been started (i.e., the user has sent at least one message in the session). Unused purchased sessions remain available until consumed.

(c) Free sessions included with the App are provided at the Developer's discretion and may be changed in future updates.

(d) Refund requests for unused sessions must be directed to Apple in accordance with Apple's refund policies.

5. Acceptable Use

You agree not to use Crux to:

(a) Process content that is unlawful, harmful, threatening, abusive, or otherwise objectionable.

(b) Seek guidance on illegal activities, self-harm, exploitation, or harm to others.

(c) Attempt to circumvent the App's content boundaries or safety measures.

(d) Reverse-engineer, decompile, or disassemble the App or its components.

(e) Use the App in any manner that could damage, disable, or impair the service.

(f) Make decisions affecting other individuals' wellbeing without their knowledge or informed consent, where professional guidance would be appropriate.

6. Account and Data

(a) Sign in with Apple is optional. If you create an account, your name and email are stored in Firebase Authentication solely for account management.

(b) You may delete your account at any time from the Profile screen. Deletion permanently removes all local data and your Firebase authentication record.

(c) Decision data is stored locally on your device. Deleting the App permanently erases all local data.

7. Age Requirement

Crux is intended for users aged 17 and older. By using the App, you confirm that you are at least 17 years of age. The Developer does not knowingly provide services to individuals under 17.

8. Intellectual Property

The App, including its design, code, system prompts, coaching methodology, and all related materials, is the intellectual property of the Developer. This Agreement does not transfer any ownership rights to you. Your decision content and conversation history remain yours.

9. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE DEVELOPER DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APP OR ANY DECISIONS MADE BASED ON AI-GENERATED CONTENT, REGARDLESS OF THE THEORY OF LIABILITY.

WITHOUT LIMITING THE FOREGOING, THE DEVELOPER ACCEPTS NO LIABILITY FOR THE OUTCOMES OF ANY DECISIONS MADE BY THE USER, WHETHER OR NOT THOSE DECISIONS WERE INFORMED BY THE APP'S AI-GENERATED CONTENT.

11. Indemnification

You agree to indemnify and hold harmless the Developer from any claims, damages, losses, or expenses arising from your use of the App, your violation of this Agreement, or any decisions you make based on the App's content.

12. Changes to This Agreement

The Developer may update this Agreement from time to time. Continued use of the App after changes are posted constitutes acceptance of the revised terms.

13. Termination

The Developer may terminate or suspend your access to the App at any time, without notice, for conduct that violates this Agreement. Upon termination, your licence to use the App is revoked.

14. Governing Law

This Agreement shall be governed by and construed in accordance with the laws of New Zealand, without regard to its conflict of law provisions.
