Terms of Service

Effective date: 2026-05-27 Last updated: 2026-05-27

These Terms of Service (“Terms”) govern your use of Glug (“the App,” “we,” “us”), operated by Olcay Kuk. By installing or using the App, you agree to these Terms. If you do not agree, do not use the App.


1. The App

Glug is a personal hydration tracker that helps you set a daily water goal, log drinks, view your history, and receive reminders. The App is intended for general wellness purposes only and is not a medical device, not a substitute for medical advice, and not intended to diagnose, treat, cure, or prevent any disease. If you have a medical condition (kidney disease, heart failure, pregnancy, on diuretics, etc.) consult a qualified healthcare professional before relying on any hydration target produced by the App.


2. Eligibility

You must be at least 13 years old (or the minimum age in your jurisdiction, e.g. 16 in some EEA countries) to use the App. By using the App you confirm you meet this requirement.


3. Your account

You can use the App entirely as a guest. If you choose to sign in (email/password), you are responsible for:

You may delete your account at any time from Settings → Delete account. Deletion is permanent and removes your cloud data within 30 days (see Privacy Policy Section 5).


4. In-app purchases and subscriptions

The App offers optional in-app purchases and subscriptions, including:

4.1 Billing

All purchases are processed by Apple App Store (iOS) or Google Play (Android). Pricing, payment, and refunds are governed by the store’s policies, not by us. We do not have direct access to your payment method.

4.2 Auto-renewal

Subscriptions renew automatically at the end of each billing period unless you cancel at least 24 hours before the period ends. You can manage or cancel subscriptions in your device’s store settings:

4.3 Refunds

Refund requests must be made directly to Apple or Google. We cannot issue refunds independently.

4.4 Restore purchases

If you reinstall the App or switch devices (within the same store account), use Settings → Restore purchases to re-activate your entitlements.

4.5 Pricing changes

We may change subscription prices. If we do, the new price applies from your next renewal, after we notify you (in the App or via the store, per the store’s notification policy).


5. Acceptable use

You agree not to:


6. Our intellectual property

The App, including all code, design, graphics, text, icons, and trademarks, is owned by Olcay Kuk and protected by intellectual property laws. We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for your own personal use, subject to these Terms.


7. Your content

You retain ownership of the content you create in the App (drink logs, custom drinks, profile information). By using cloud sync, you grant us a limited license to store, process, and transmit that content solely to operate the App for you.


8. Notifications

The App schedules local notifications on your device. We do not run a push server. You can disable notifications at any time in your device’s system settings or by setting reminder mode to “Off” in the App.


9. Third-party services

The App relies on third-party services described in the Privacy Policy, including Supabase, Apple App Store, Google Play, RevenueCat, and OpenWeatherMap. These services have their own terms which apply to your use of those services.


10. Disclaimers

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that:

You use the App at your own risk.


11. Limitation of liability

To the maximum extent permitted by law, Olcay Kuk is not liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising from your use of the App, even if we have been advised of the possibility of such damages.

Our total liability for any claim relating to the App is limited to the greater of (a) the amount you paid us in the twelve months before the claim or (b) USD 25.

This section does not limit liability for fraud, gross negligence, willful misconduct, death, or personal injury caused by our negligence, or any other liability that cannot be excluded under applicable law.


12. Termination

You may stop using the App at any time by uninstalling it. We may suspend or terminate your access to the App, including any cloud sync, if you violate these Terms. Termination does not entitle you to a refund of any active subscription or in-app purchase (subject to store policies).


13. Changes to these Terms

We may update these Terms as the App evolves. If we make a material change, we will notify you in the App and update the “Last updated” date above. Continued use of the App after a change means you accept the updated Terms.


14. Governing law

These Terms are governed by the laws of Republic of Turkey, without regard to conflict-of-laws principles. Disputes will be resolved in the competent courts of Republic of Turkey, unless mandatory consumer protection laws in your country provide otherwise.
