Welcome to Waltermelon! These Terms & Conditions ("Terms") govern your use of the Waltermelon mobile application (the "App"), developed and operated by Paweł Ławiński and Mateusz Tylman ("we", "us", or "our"). By accessing or using the App, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use the App.

Waltermelon is a hydration tracking app available on iOS and Android. It allows you to log drinks, track your daily water intake, set hydration goals, and connect with friends. Please note that Waltermelon is not intended to diagnose, treat, cure, or prevent any disease, and should not be used as a substitute for medical advice.

For details about how we collect and process your personal data, please refer to our Privacy Policy (coming soon).

If you have any questions, contact us at support@waltermelon.app.

Waltermelon is available for users aged 4 and above. However, if you are under 13 years of age, you may only use the App under the supervision and with the consent of a parent or legal guardian.

By creating an account, you (or your parent/guardian) confirm that you meet the age requirement and have the legal capacity to enter into a binding agreement under applicable law.

You can create an account using your email and password, or by signing in with your Google or Apple account. You are responsible for keeping your login credentials secure and for all activity under your account.

You may delete your account at any time via the App settings or by contacting us at support@waltermelon.app.

Waltermelon offers optional premium features through in-app subscriptions, available via the Apple App Store and Google Play. These subscriptions are billed and managed by the respective app store and are subject to their terms and conditions.

Subscription details, including pricing, duration, and renewal terms, are shown in the App at the time of purchase. Unless canceled at least 24 hours before the end of the current period, subscriptions automatically renew.

You can manage or cancel your subscription at any time through your Apple or Google account settings. We do not process payments directly and cannot issue refunds. Refund requests must be handled through the app store used for the purchase.

We may add, remove, or change features within the App—including those available through premium subscriptions—at any time. We aim to improve Waltermelon continuously, and this may involve adjusting the content or functionality of both free and paid features. We will notify you of any material changes where required by law or platform policies.

You agree to use the App only for lawful purposes and in accordance with these Terms. You must not:

• Access or use the App in any way that violates applicable laws or regulations;
• Attempt to reverse engineer, decompile, or modify any part of the App;
• Interfere with or disrupt the App, its servers, or its networks;
• Upload or distribute malware, spam, or harmful content;
• Attempt to gain unauthorized access to other users' data or accounts;
• Use the App to harass, threaten, or harm others;
• Use the App for any commercial purpose without our prior written consent.

We reserve the right to suspend or terminate your access to the App if you violate these rules or otherwise misuse the service.

Waltermelon is designed to help you track your hydration and encourage healthy habits. However, it is not a medical or health application.

This App is not intended to diagnose, treat, cure, or prevent any disease. All hydration goals and suggestions are based on general formulas and the personal data you provide, such as age, weight, activity level, and environment.

We are not medical professionals, and the App does not provide medical advice. You should consult a doctor or qualified healthcare provider if you have any specific health concerns or medical conditions. You can manually adjust your hydration goal in the App at any time.

Use Waltermelon as a helpful tool to support your hydration habits, but always listen to your body and consult a professional if you're unsure about your needs.

Waltermelon includes social features that allow users to connect with friends and view each other's hydration stats. By default, all accounts have a public profile visible to other users.

Your public profile may include your name, avatar, hydration streak, and intake progress. You are responsible for the content you add to your profile and must ensure it is appropriate, respectful, and lawful.

You may not upload or share content that is offensive, abusive, illegal, or infringes on the rights of others. We may remove content, restrict access, or suspend accounts that violate these Terms. Users can report inappropriate behavior or profiles directly through the App.

By uploading content to your profile, you grant us a worldwide, non-exclusive, royalty-free license to use, display, and distribute that content within the App.

We respect your privacy. When you use Waltermelon, we collect certain personal information—such as your age, weight, height, activity level, climate, gender, pregnancy, and breastfeeding status—to calculate your daily hydration goal. You can override this goal at any time.

We also use analytics tools and third-party services (like Supabase, PowerSync, Firebase, and Appsflyer) to help us improve the App and understand how it's used. We do not sell your data.

If you choose to connect Waltermelon with Apple Health (iOS) or Health Connect (Android), hydration data will be read and written only with your permission.

The App may interact with or include integrations from third-party services. We are not responsible for the terms, content, privacy practices, or reliability of these services. Your use of them is subject to their own terms and policies.

For full details on how we collect, use, and protect your data, please refer to our Privacy Policy.

All rights to the Waltermelon app, including its design, code, content, branding, and features, are owned by Paweł Ławiński and Mateusz Tylman or their respective licensors.

You are granted a personal, non-exclusive, non-transferable, revocable license to use the App for your own non-commercial purposes. You may not copy, modify, distribute, sell, or reverse-engineer any part of the App without our prior written consent.

All trademarks, logos, and names associated with Waltermelon are protected and may not be used without permission.

We welcome your feedback, ideas, and suggestions to improve Waltermelon. By submitting feedback through the App or via email, you grant us the right to use it without restriction or obligation to compensate you.

From time to time, we may offer access to experimental or beta features. These features are in development and may change, break, or be removed at any time without notice. By using beta features, you understand that they may not function as expected and are provided "as is."

You can delete your Waltermelon account at any time through the App settings or by contacting us at support@waltermelon.app. Deleting your account will permanently remove your personal data from our systems, in accordance with our Privacy Policy.

We may suspend or terminate your access to the App if you violate these Terms, misuse the service, or engage in behavior that harms other users or the platform.

We also reserve the right to discontinue or modify the App at any time.

These Terms are governed by the laws of the Republic of Poland and applicable European Union regulations.

If you have a concern or dispute, we encourage you to contact us first at support@waltermelon.app so we can try to resolve it informally.

If a dispute cannot be resolved, it will be subject to the jurisdiction of the courts located in Poland, unless applicable consumer protection laws in your country provide otherwise.

The App is provided "as is" and "as available" without warranties of any kind. We do not guarantee that the App will be uninterrupted or error-free, or that any content is accurate or reliable.

To the extent permitted by law, we are not liable for indirect, incidental, or consequential damages, including loss of data, profit, or health outcomes.

You agree to indemnify and hold harmless the creators of Waltermelon from any claims, damages, or liabilities arising from your misuse of the App or your violation of these Terms.

Sections that, by their nature, should survive account termination—including Intellectual Property, Disclaimers, Limitation of Liability, and this Indemnification clause—will remain in effect even after your account is deleted.

We may update these Terms & Conditions from time to time to reflect changes in the App or applicable laws. When we make significant changes, we will notify you through the App or by other reasonable means.

The updated Terms will take effect once published. By continuing to use Waltermelon after the changes take effect, you agree to the revised Terms. If you do not agree, you should stop using the App and delete your account.
