Terms of Service

These terms describe how NERYUNE may be used. Short and in plain language, because that is how we prefer to work.

1. What NERYUNE is

NERYUNE is a wellness app for tracking daily fluid intake. It is not a medical device and it does not provide medical advice, diagnosis or treatment.

NERYUNE provides an estimated hydration target for general wellness. Individual needs may vary. This is not medical advice.

If you have a condition that affects fluid intake, follow the advice of a medical professional.

2. The free core

The free part of NERYUNE: manual water logging with the Today view, a fixed daily goal you set yourself, and CSV export of your data. Everything you have logged always stays visible and deletable on your device, and CSV export works whether or not you subscribe.

3. Subscriptions (NERYUNE Premium)

The intelligent layer of NERYUNE is offered as the NERYUNE Premium subscription: the adaptive daily goal (weight, activity, weather), smart reminders, all drink types with hydration factors, all analytics and history views, the Apple Health (iOS) and Health Connect (Android) integrations, and achievements. New subscribers may be offered a free trial, currently 14 days; after the trial the subscription renews at the shown price unless it is cancelled before the trial ends. Subscriptions are billed and managed by Google Play on Android and by the App Store on iOS, under those stores' own terms. Prices, renewals, refunds and cancellation are handled in your store account; you can cancel at any time through the store. Uninstalling the app does not cancel a subscription. Paid features never remove anything from the free core.

4. Acceptable use

Use NERYUNE for personal, lawful purposes. Do not attempt to disrupt or overload the service, gain unauthorized access to it, or present content you share (for example, share cards) as coming from someone else.

5. No warranty of outcomes

NERYUNE is provided "as is". All numbers the app shows are estimates for general wellness, not guarantees. We do not promise any specific wellness or health outcome and, to the extent permitted by applicable law, we are not liable for decisions made on the basis of the app's estimates.

6. Changes to these terms

We may update these terms, for example when new features ship. The current version is always published on this page with its date. Continued use of the app after a change means you accept the updated terms.
