Effective date: October 29, 2026 Last updated: November 4, 2026
These Terms of Use ("Terms") form an agreement between you and Colyden LLC ("Enphana," "we," "us," or "our") governing your use of the Enphana mobile app and associated documentation (collectively, the "App").
If you do not agree to these Terms, do not use the App.
Contact: support@colyden.com
These Terms apply to your relationship with Colyden LLC. If you download the App through the Apple App Store, your use is also subject to applicable Apple terms, including Apple's standard end-user license agreement. If you download it through Google Play, your use is also subject to Google Play's terms of service. If a mandatory store term conflicts with these Terms, that mandatory store term controls for the conflict.
1. Eligibility and authority
The App is a general-audience service and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we learn that a child under 13 has provided personal information through the App, we will delete it. See our Privacy Policy for details.
2. The App is a personal wellness tool, not medical care
Enphana helps you record everyday observations and explore possible patterns in your own information. It is not a medical device, healthcare provider, emergency service, diagnostic tool, treatment plan, or substitute for professional medical advice, diagnosis, or treatment.
The App may show correlations, trends, suggestions, nutrition values, or experiment results. These are informational observations, not proof of cause and effect, medical conclusions, or individualized clinical advice. You are solely responsible for decisions you make based on the App. Read the Health and Safety Disclaimer before using the App.
3. License to use the App
Subject to these Terms and your applicable subscription status, Enphana grants you a limited, personal, non-exclusive, non-transferable, revocable license to download and use the App on devices you own or control. The App is licensed, not sold.
You may not, unless permitted by applicable law:
- copy, modify, distribute, sell, lease, sublicense, or exploit the App;
- reverse engineer, decompile, or attempt to derive source code;
- interfere with the App, its security, or another person's use of it;
- use the App unlawfully, deceptively, or in a way that infringes another person's rights; or
- remove proprietary notices.
4. Your information and device responsibility
You are responsible for the accuracy, legality, and appropriateness of information you enter, import, export, or share. Do not enter information that you are not authorized to use.
Core App content is stored locally on your device. You are responsible for protecting your device, local backups, and exported files. Enphana cannot recover locally stored content after deletion, device loss, corruption, or uninstall unless you have retained a usable backup, including a cloud backup you created (see Section 5). See the Privacy Policy, Consumer Health Data Privacy Policy, and Data Deletion Policy for details.
5. Connected services and permissions
Some features are optional and require device permissions, Apple Health, Health Connect, camera or microphone and speech-recognition access, RevenueCat, or an app-store account. The camera can be used for barcode and nutrition-label scanning; the microphone can be used for voice food search. Those services are not controlled by Enphana and may have separate terms and privacy policies. Your use of them is subject to their applicable terms.
You can decline or revoke permissions, although this may make a feature unavailable. Apple Health and Health Connect data are read only and used only to provide the App's requested import and wellness-tracking features.
Cloud backups. With an Enphana account and active access, you can create up to three cloud backups of your App data. Cloud backups are a convenience, not a guarantee: we do not promise they will always be available or complete, so keep your own exports as well. If your access ends, cloud backups become eligible for deletion 90 days later and are removed by scheduled cleanup. Deleting your account deletes them immediately.
AI links and third-party AI. You can create a temporary link that lets an AI app you choose read selected Enphana information. Anyone with the link can read it until it expires (within 72 hours) or you revoke it. You decide what to share and with which provider. AI providers are not controlled by Enphana, may have their own terms and privacy practices, and may produce inaccurate, incomplete, or unsafe output. AI output is not medical advice. AI responses are not all handled the same way. Project proposals and AI Profile changes that need manual review are presented for your approval before saving. Certain valid, trusted AI Profile return links can apply changes automatically when you open them in Enphana, without a separate Save confirmation. The App displays the result and provides an undo option where available. Review the information supplied by an AI provider, since it may be incomplete or inaccurate.
Share links. You can share a recipe or meal through a link that anyone who has it can open and copy until it expires (30 days) or you revoke it. Share only content you have the right to share.
6. Subscription and paid access
Premium provides ongoing access to the App's creation and editing features, and to cloud backups, AI links, and share links, after an initial trial. If your trial or subscription ends, you retain access to your existing local history and available export, import, and deletion controls, but cannot create or update paid-feature content, or create cloud backups, AI links, or share links, without an active trial or subscription. Subscription purchases are made through Apple App Store or Google Play and are subject to the applicable store's terms, billing rules, and refund process. RevenueCat supports subscription entitlement administration.
Pricing, billing period, taxes, auto-renewal, free-trial or introductory-offer details, cancellation instructions, and availability are disclosed by the store before purchase and are incorporated into your purchase. Manage or cancel your subscription through the store account used to purchase it. See the Subscription Terms for Enphana-specific details.
7. Intellectual property
The App, its software, visual design, text, trademarks, and other content are owned by Enphana or its licensors and protected by law. These Terms do not grant you any ownership rights except the limited license above. You retain rights in the information you enter, subject to the rights needed to operate the App as described in the Privacy Policy.
8. Feedback
If you send us ideas, feedback, or suggestions, you grant us a non-exclusive, worldwide, royalty-free right to use them to operate, improve, or promote Enphana without compensation. We will not identify you as the source without your permission. Do not include sensitive health information, passwords, one-time codes, or payment information in feedback.
9. Changes, availability, and termination
We may change, suspend, or discontinue all or part of the App, including features or subscriptions, as permitted by law. We may update these Terms by posting a revised version with a new effective date and giving additional notice when required. If you do not agree to revised Terms, stop using the App.
We may suspend or terminate access if you materially violate these Terms, misuse the App, or if required for legal or security reasons. You may stop using the App at any time. Ending access or deleting an Enphana account does not automatically cancel an app-store subscription or delete content stored locally on your device; manage subscriptions through the applicable store and local data through the App's deletion controls.
10. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE." ENPHANA DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION. WE DO NOT WARRANT THAT THE APP WILL PRODUCE ACCURATE, COMPLETE, OR CLINICALLY VALID RESULTS.
Nothing in these Terms excludes a warranty, right, or remedy that cannot lawfully be excluded.
11. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, ENPHANA AND ITS AFFILIATES, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THE APP OR THESE TERMS.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) US$100.
Some jurisdictions do not allow certain exclusions or limitations. In those jurisdictions, these provisions apply only to the extent permitted by law.
12. Governing law and disputes
These Terms are governed by the laws of the State of Colorado, excluding its conflict-of-laws rules, except where the law of your residence requires otherwise. The state courts located in Jefferson County, Colorado, and the United States District Court for the District of Colorado will have exclusive jurisdiction over disputes, except where applicable law provides otherwise.
13. General terms
If a provision is unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our written consent; we may assign them in connection with a merger, acquisition, or sale of assets. These Terms and the documents they incorporate are the entire agreement between you and Enphana about the App.
