Otterly — Terms of Use

These Terms of Use ("Terms") govern your use of Otterly, a hydration and water-tracking app for iPhone and Apple Watch. Please read them carefully.

Last updated: 4 July 2026

1. Acceptance and who we are

Otterly is provided by Huseyin Yenilmez, an individual developer based in Türkiye ("we", "us"). By downloading, installing, or using Otterly, you agree to these Terms. If you do not agree, please do not use the app.

2. License to use the app

We grant you a personal, non-commercial, non-exclusive, non-transferable, revocable license to use Otterly on Apple devices that you own or control, in accordance with these Terms and Apple's usage rules. You may not copy, modify, reverse-engineer, resell, or redistribute the app except as permitted by law.

3. Subscriptions (Otterly+)

Otterly offers optional Otterly+ purchases that unlock the "plus" entitlement:

Monthly — otterly.plus.monthly — $1.99 / month
Annual — otterly.plus.annual — $11.99 / year, with a 7-day free trial
Lifetime — otterly.plus.lifetime — $29.99 one-time purchase

The following standard terms apply to the auto-renewing subscriptions (Monthly and Annual):

Your subscription renews automatically unless you cancel it at least 24 hours before the end of the current period.
You can manage or cancel your subscription at any time in your Apple Account settings.
Payment is charged to your Apple Account upon confirmation of purchase.
The renewal amount is charged within 24 hours before the end of the current period.
Any unused portion of a free trial is forfeited when you purchase a subscription.
Refunds are handled by Apple, not by the developer. Please request refunds through Apple.
Family Sharing is supported.

The Lifetime option is a one-time purchase and does not auto-renew.

4. Apple's Standard EULA

In addition to these Terms, your use and any purchases are also governed by Apple's Standard End User License Agreement (the Licensed Application EULA), available at:
https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

5. Acceptable use of social features

If you use Otterly's optional social features (friends, duels, leagues), you agree that:

Your display name must not be offensive, hateful, obscene, or impersonate another person or brand.
You will play fairly — no cheating, exploiting, or manipulating scores, streaks, or leaderboards.
We may remove abusive accounts or content, and reset manipulated scores, to keep the community fair and friendly.

6. Health disclaimer

Otterly provides general hydration guidance only and is not medical advice. Hydration needs vary from person to person and by circumstance. Always consult a doctor or qualified healthcare professional for any medical or health decisions, and do not rely on Otterly for medical purposes.

7. Disclaimer of warranties

Otterly is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to fitness for a particular purpose, accuracy, or uninterrupted operation. We do not guarantee that the app will be error-free or that goals, reminders, or weather-based adjustments will be accurate for your situation.

8. Limitation of liability

To the maximum extent permitted by applicable law, we will not be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, arising out of or related to your use of Otterly. Nothing in these Terms limits any liability that cannot be limited under applicable law, including your statutory consumer rights.

9. Governing law

These Terms are governed by the laws of Türkiye, without regard to conflict-of-law principles. This does not deprive you of any mandatory consumer protections available to you where you live.

10. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date above. Your continued use of Otterly after changes take effect constitutes acceptance of the updated Terms.
