Terms of Use

Acceptance of Terms

By downloading, installing, or using Aether ("the App"), you agree to be bound by these Terms of Use ("Terms") and our Privacy Policy. These Terms form a legally binding agreement between you and Aether Health ("Aether," "we," "us," or "our"). Aether Health is operated by its developer, who runs the Aether application. You can contact us at hello@aetherhealth.app.

If you do not agree to these Terms, do not install or use the App. By using Aether, you confirm that you are at least 13 years old and have the legal capacity to enter into this agreement. If you are using Aether on behalf of an organisation, you represent that you have the authority to bind that organisation to these Terms.

These Terms apply to your use of the Aether iOS application available on the Apple App Store. The Apple Media Services Terms and Conditions also apply to your use of the App, and section 12 sets out terms that apply because you got Aether from the App Store.

Description of Service

Aether is an iPhone health and wellness application that brings data from your wearable devices and Apple Health into one private daily view. The App:

• Reads health and fitness data from Apple Health (HealthKit), including data from Apple Watch and from other apps and devices that write to Apple Health. Aether only reads this data; it does not write anything to Apple Health.
• Connects, if you choose, to your Oura account (Oura API v2) and your WHOOP account (WHOOP developer API) using OAuth sign-in, to import ring- and strap-derived metrics
• Calculates a personalised daily Aether Score (0–100) with sleep, recovery, and activity sub-scores, together with trends and an on-device daily finding
• Lets you add lab values you already have (typed in, imported from Apple Health clinical records, or scanned from a PDF or photo on your iPhone) and confirm them before they are saved
• Offers an optional Cloud Coach that answers questions about your logged days (see Section 3 and our Privacy Policy)
• Offers optional extras: a daily summary notification, a Home Screen widget, a workout Live Activity, a shareable score card, an export of your log that you can copy or share, and a local air-quality reading

Aether is a paid subscription app. There is no free version: using Aether requires an active Aether Premium subscription or free trial (see Section 5).

We reserve the right to modify, suspend, or discontinue any feature of the App at any time. We will endeavour to provide reasonable notice for material changes that affect existing functionality you rely on.

Health Disclaimer

Specifically:

• Aether is not a substitute for professional medical advice, diagnosis, or treatment.
• Aether has not been approved, cleared, or authorised by any medical regulatory body (including the FDA, CE, or equivalent authority) as a medical device.
• Data accuracy is subject to the limitations of your connected devices (Apple Watch, Oura Ring, WHOOP, and any other device or app that writes to Apple Health). Aether inherits those limitations and does not independently validate health readings.
• Sleep staging, HRV, and readiness algorithms are approximations based on consumer wearable data, not clinical-grade measurements.
• The Aether Score is a proprietary composite metric for personal reference only — it does not represent a clinically validated measure of your health status.
• Lab values are shown as you enter or confirm them. Aether does not interpret lab results, does not say whether any value is normal or abnormal, and does not replace review by your doctor or the laboratory that issued them. Scanned or imported values may be read incorrectly; you are responsible for checking each value against the original report before saving it.
• Cloud Coach replies, and any daily summary notification text it generates, are produced automatically by a third-party AI model. They may be incomplete or wrong, are not medical advice, and are not a diagnosis or treatment plan.
• Aether is not designed for emergencies. If you think you may have a medical emergency, call your local emergency number immediately.

Always consult a qualified healthcare professional:

• Before making any changes to your exercise, sleep, diet, or medication based on data or insights from Aether.
• If you experience any symptoms, health concerns, or unexpected changes in your health metrics.
• For any condition that may be indicated by your health data.

Do not delay or disregard professional medical advice because of anything you have seen or read in Aether.

Account & Device Requirements

Device requirements:

• An iPhone running iOS 26 or later.
• An Apple Watch is recommended for HealthKit heart rate and activity data, but not strictly required.
• An Oura Ring or a WHOOP strap, with its own account, if you wish to use the Oura or WHOOP connections.

Accounts:

• Aether does not require you to create an account. You can use the App without registering.
• There is no Aether account or Aether sign-in. Subscriptions are tied to your Apple ID through the App Store.
• Oura and WHOOP users must authorise Aether via OAuth through their existing Oura or WHOOP account. Those accounts are governed by Oura's and WHOOP's own terms and policies.

You are responsible for maintaining the security of your device and for ensuring that only authorised users have access to the App on your device. Aether stores credentials in the iOS Keychain — do not share your device passcode or Face/Touch ID with others if you want to keep your health data private.

Subscription & Billing

Aether offers one subscription, Aether Premium, which includes every feature of the App. It is available as a yearly or a monthly plan:

Subscription terms:

• Billing: Subscriptions are billed yearly or monthly, depending on the plan you choose, through your Apple ID account to the payment method associated with it.
• Free trial: Both plans start with a 7-day free trial. When the trial ends, it converts automatically to a paid subscription at the price of the plan you chose ($24.99 per year or $2.99 per month) unless you cancel at least 24 hours before the trial ends. You are not charged if you cancel in time. The App Store offers one free trial per Apple Account for Aether Premium, and trial eligibility is determined by the App Store.
• After the trial or subscription ends: Without an active trial or subscription, the App shows the subscription screen instead of its features. The data Aether stored on your iPhone is not deleted, and you can still export your log from that screen.
• Auto-renewal: Subscriptions automatically renew at the end of each billing period (each year or each month) at the then-current price unless cancelled at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the end of the current period.
• Cancellation: You may cancel your subscription at any time through your iPhone's Settings → [your name] → Subscriptions. Cancellation takes effect at the end of the current billing period — you retain access to Premium features until then.
• Refunds: All refund requests are handled by Apple in accordance with Apple's App Store refund policy. Aether Health does not directly issue refunds. To request a refund, visit reportaproblem.apple.com.
• Price changes: Apple may adjust App Store pricing in certain regions. If prices change, you will receive notice from Apple before your next billing period.
• Offers: From time to time, Apple or Aether Health may offer discounted pricing to some customers, for example a win-back or promotional offer for people whose trial or subscription has ended (such as a reduced price for the first year of the yearly plan). Any such offer is at Apple’s and our discretion, eligibility is determined by the App Store, and the price and duration shown on the purchase screen apply. After the offer period, the subscription renews at the regular price unless you cancel at least 24 hours before renewal.
• Cloud Coach limits: Cloud Coach has a daily reply limit: 5 replies a day during the free trial and 20 a day on a paid subscription.

Family Sharing availability for Aether Premium is subject to Apple's Family Sharing policies and may be enabled or changed at our discretion.

User Responsibilities

When using Aether, you agree to:

• Use the App only for its intended personal wellness purpose, in accordance with these Terms and all applicable laws.
• Grant accurate and appropriate device permissions — providing incorrect permissions may lead to inaccurate or incomplete health data.
• Not rely on Aether for any medical or clinical purpose, including but not limited to diagnosis, monitoring of a medical condition, or making treatment decisions.
• Not attempt to reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the App.
• Not use automated tools, scripts, or bots to access or interact with the App or any APIs used by the App.
• Not attempt to access, modify, or interfere with data belonging to other users.
• Not use the App in any way that violates Apple's App Store Guidelines or the terms of any connected third-party service (Oura, WHOOP, OpenRouter, etc.).
• Ensure your device software is reasonably up to date for security purposes.

You understand that your health data is generated by third-party devices and platforms (Apple Watch, Oura Ring, WHOOP, and others that write to Apple Health) and that the accuracy of Aether's insights depends directly on the accuracy of that underlying data. Aether is not responsible for inaccuracies originating from your wearable devices or the third-party APIs we access on your behalf.

Intellectual Property

All intellectual property in the Aether application — including but not limited to the software code, algorithms, Aether Score methodology, visual design, user interface elements, logos, trademarks, and written content — is owned exclusively by Aether Health and is protected by applicable intellectual property laws.

These Terms grant you a limited, non-exclusive, non-transferable, revocable licence to use the App on your personal Apple devices, solely for your own personal health and wellness purposes. This licence does not include the right to:

• Copy, reproduce, or redistribute any part of the App or its content
• Create derivative works based on the App
• Use Aether's name, logo, or trademarks without prior written permission
• Use the App for commercial purposes or on behalf of third parties without written authorisation

Your health data remains yours. We do not claim ownership of the health data generated by your devices or the insights derived from it within your personal use of the App.

Limitation of Liability

Disclaimer of warranties: Aether is provided "as is" and "as available," without warranties of any kind, whether express or implied. To the maximum extent permitted by applicable law, Aether Health expressly disclaims all warranties, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

We do not warrant that:

• The App will be uninterrupted, error-free, or available at all times
• Health data or insights will be accurate, complete, or current
• The App will meet your specific health or wellness requirements
• Any defects or errors will be corrected

Limitation on damages: To the maximum extent permitted by applicable law, Aether Health, its operators, and any affiliates will not be liable for:

• Any indirect, incidental, special, consequential, or punitive damages
• Loss of data, profits, revenue, or business opportunities
• Personal injury, property damage, or health outcomes arising from reliance on Aether's insights or data
• Damages arising from third-party device inaccuracies, API unavailability, or interruptions in HealthKit, Oura, WHOOP, OpenRouter, or other third-party services
• Unauthorised access to or alteration of your health data

In all cases, our total aggregate liability to you for all claims arising out of or relating to Aether shall not exceed the greater of (a) the amount you paid for your Aether subscription in the 12 months preceding the claim, or (b) USD $100.

Some jurisdictions do not allow the exclusion of certain warranties or limitation of liability. In such jurisdictions, our liability is limited to the minimum extent permitted by law.

Indemnification

You agree to indemnify, defend, and hold harmless Aether Health and its operators from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or in connection with:

• Your use or misuse of the App
• Your violation of these Terms
• Your violation of any applicable law or regulation
• Your reliance on Aether's health insights for medical or clinical decisions contrary to the warnings in these Terms
• Any claim made by a third party arising from your use of the App

This indemnification obligation does not apply to any claims arising from Aether Health's own gross negligence or wilful misconduct.

Termination

By you: You may stop using Aether and delete the App from your device at any time. If you have an active subscription, cancel it through iOS Settings before deleting to avoid future charges (see Section 5).

By us: We may suspend or terminate your access to Aether, or to specific features, at any time if:

• You violate these Terms
• We are required to do so by applicable law
• We discontinue the App or a feature (with reasonable notice where practicable)
• Continued access poses a security or integrity risk

Upon termination, your right to use the App ceases immediately. If you have paid for a subscription period that extends beyond termination due to our action (rather than your violation of these Terms), we will work with Apple to arrange an appropriate refund for the unused period.

Sections 3 (Health Disclaimer), 7 (Intellectual Property), 8 (Limitation of Liability), 9 (Indemnification), and 11 (Governing Law) survive termination of these Terms.

Governing Law

These Terms are governed by and construed in accordance with applicable laws. As Aether is available to users globally, the following applies:

Any disputes arising from these Terms or your use of Aether will be resolved in accordance with the laws of the jurisdiction in which Aether is operated, except where mandatory consumer protection laws in your country of residence provide greater protections (which shall apply to that extent).

Notwithstanding the above, users in the European Economic Area retain the right to bring claims in their country of habitual residence and have those claims resolved under applicable EU consumer protection laws.

We strongly prefer to resolve any disputes directly and informally. Before initiating any formal proceedings, please contact us at hello@aetherhealth.app to describe your concern — we will make every reasonable effort to reach a resolution.

Apple App Store Terms

These Terms are the end user license agreement (EULA) for Aether. If you got Aether from the Apple App Store, the following also applies, and it takes priority over anything else in these Terms that conflicts with it:

• Agreement with us, not Apple. These Terms are between you and Aether Health only, not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for Aether and its content.
• Scope of license. We grant you a limited, non-transferable license to use Aether on any Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. Aether may also be used by other accounts associated with you through Family Sharing or volume purchasing, where those apply.
• Maintenance and support. We are solely responsible for providing maintenance and support for Aether, as described in these Terms or as required by law. Apple has no obligation to provide any maintenance or support for Aether.
• Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If Aether fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for Aether to you. To the maximum extent permitted by law, Apple has no other warranty obligation for Aether, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are our responsibility.
• Product claims. We, not Apple, are responsible for addressing any claims by you or a third party relating to Aether or your possession or use of it, including (i) product liability claims; (ii) any claim that Aether fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation, including in connection with Aether's use of HealthKit.
• Intellectual property. If a third party claims that Aether or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement and discharge of that claim.
• Legal compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Developer contact. Questions, complaints or claims about Aether go to Aether Health at hello@aetherhealth.app (see Contact Information below).
• Third-party terms. You must comply with applicable third-party terms when using Aether, for example your wireless data service agreement.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. Once you accept these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

Changes to Terms

We may update these Terms from time to time. When we make material changes, we will:

• Update the "Last updated" date at the top of this page.
• Post a notice within the Aether app for significant changes.
• Where required by applicable law, seek fresh acceptance of updated Terms before they apply to you.

Non-material changes (such as formatting improvements, clarifications, or corrections that do not affect your rights) take effect immediately upon posting. Material changes take effect 30 days after notice, or at your next app session after the notice period, whichever is later.

Continued use of Aether after the effective date of updated Terms constitutes your acceptance of the updated Terms. If you do not agree, you should stop using the App and cancel any subscription before the changes take effect.

The current version of these Terms is always available at aetherhealth.app/terms.
