Read this part even if you read nothing else
Cold water immersion and heat exposure carry real physical risk, including cold shock, involuntary gasping, drowning, arrhythmia, fainting and hyperthermia. Kelvy is a log and a timer. It is not a medical device, it does not supervise you, and it cannot tell when you are in trouble. Never plunge alone. Get out when your body says stop.
These Terms of Use are an agreement between you and Avokado Labs (“we”, “us”), Republic of Türkiye, covering the Kelvy iPhone app and its Apple Watch app (“Kelvy”, “the app”). By downloading or using the app you agree to them. If you do not agree, do not use the app.
How we handle information is described separately in our Privacy Policy, which forms part of this agreement.
We grant you a personal, non-exclusive, non-transferable, revocable licence to use Kelvy on Apple devices that you own or control, as permitted by the App Store Terms of Service. You may not sell, rent, sublicense, reverse engineer, decompile or attempt to derive the source code of the app, except to the extent that applicable law expressly allows it.
Kelvy is not medical advice and is not a medical device. Nothing in the app diagnoses, treats, cures or prevents any condition. The protocols, durations, temperatures and defaults it offers are conveniences for logging, not recommendations, and they are not tailored to you.
Cold water immersion can trigger cold shock, involuntary gasping and hyperventilation, and can cause drowning even in shallow water. It can provoke dangerous heart rhythms. Heat exposure can cause fainting, dehydration and hyperthermia. Risk is higher if you are pregnant, have a heart condition, high or low blood pressure, epilepsy, diabetes, Raynaud’s, a respiratory condition, or if you have consumed alcohol or drugs.
You agree that:
Goals, streaks and reminders exist to help you keep a record. They are not a reason to stay in longer than is safe. Do not let a number in an app override what you feel.
Temperatures, durations, heart rate, heart rate variability and calories shown in Kelvy come from what you enter and from sensors and data provided by Apple devices and Apple Health. We do not warrant that any of it is accurate, complete or fit for any particular purpose, and you must not rely on it for medical, clinical, diagnostic or safety decisions.
Kelvy Pro is an auto-renewing subscription sold through the App Store. Current plans and prices are shown in the app before purchase, in your local currency as set by Apple.
Where a plan is offered with a free trial, the trial length is shown in the app before you purchase. Eligibility is determined by Apple, and a free trial is generally available only once per Apple Account per subscription group. If you have already used a trial, the app will not offer one.
Unless you cancel at least 24 hours before the trial ends, it converts to a paid subscription and your Apple Account is charged. Any unused portion of a free trial is forfeited when you purchase a subscription, where Apple’s rules require this.
You manage and cancel your subscription in your Apple Account settings, not in Kelvy — we cannot cancel it for you. Deleting the app does not cancel a subscription.
Refunds are handled by Apple under the App Store Terms of Service. We do not process payments and cannot issue refunds. Requests go to Apple at reportaproblem.apple.com.
If you are a consumer in the EU or UK, your statutory withdrawal rights are unaffected by this section.
Your sessions are stored on your device, not on our servers. That means we cannot recover them for you. If you lose or reset your device without a backup, or delete the app, the history is gone. Use the CSV export if your history matters to you.
You are responsible for what you write into notes, and for keeping your own backups.
Do not use Kelvy to break the law, to interfere with the app or Apple’s services, to circumvent the subscription, or to build a competing product from its code or assets.
Kelvy, including its software, design, text, icons and name, belongs to us and is protected by copyright and other laws. These terms give you a licence to use the app, not ownership of it. Your own session data belongs to you.
We may change, suspend or discontinue features, and we may update these terms. When we update them, we will change the date at the top of this page; material changes will be signalled in the app before they take effect. Continuing to use the app after a change means you accept the updated terms.
You may stop using Kelvy at any time by deleting it. We may suspend or end your licence if you materially breach these terms. Sections that by their nature should survive — ownership, disclaimers, limitation of liability and governing law — survive termination.
To the maximum extent permitted by law, Kelvy is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that data will be preserved.
Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.
To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, lost profits or loss of goodwill, arising out of your use of Kelvy. Our total liability for any claim relating to the app is limited to the amount you paid us for it in the twelve months before the claim arose.
Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by our negligence, or for fraud.
This agreement is between you and us, not with Apple, and Apple is not responsible for Kelvy or its content. Apple has no obligation to provide maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price, if any; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
We, not Apple, are responsible for addressing any claim relating to the app, including product liability claims, claims that the app fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation. We, not Apple, are responsible for the investigation, defence, settlement and discharge of any third-party claim that the app infringes intellectual property rights.
You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
Apple and Apple’s subsidiaries are third-party beneficiaries of these terms, and upon your acceptance they have the right to enforce them against you.
These terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-law rules. If you are a consumer, this does not deprive you of the protection of mandatory consumer law in your country of residence, or of the right to bring proceedings there.
