Terms of Use
Last updated: August 17, 2026
These terms are the agreement between you and JUNAID MOHAMMED ABDUL NAYEEM for the use of Water Tracker: Sipster. By downloading or using the app you accept them. The End User Licence Agreement covers the licence to the software itself and forms part of these terms.
1. The licence you get
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Sipster on devices you own or control, for your own non-commercial use. You may not copy, sell, rent, sublicense, reverse-engineer or redistribute the app, remove its notices, or use it to build a competing product. See the EULA for the full terms of that licence.
2. What the free version includes
The free version is not a trial and does not expire. Logging, your daily goal, reminders, four quick-add cups and the last 30 days of history are free for as long as you use the app. Nothing you have already logged is removed if you stop paying for Pro. The free version displays advertising.
3. Sipster Pro subscriptions
| Plan | Product identifier | Price (USD) |
|---|---|---|
| Pro Weekly | sipster.pro.weekly | $3.99 per week |
| Pro Monthly | sipster.pro.monthly | $9.99 per month |
Prices are shown in the app in your local currency before you confirm, and may differ by country and change over time. The price you see at the moment of purchase is the price that applies.
- Auto-renewal. Subscriptions renew automatically at the end of each period unless cancelled at least 24 hours before that period ends. Your store account is charged for the renewal within 24 hours of the end of the current period.
- Billing. All payments are taken by Apple (App Store) or Google (Google Play). We never receive your payment details.
- Managing or cancelling. Cancel any time in your store account settings — iOS: Settings → your name → Subscriptions; Android: Play Store → Payments and subscriptions → Subscriptions. The app links you straight there. Deleting the app does not cancel a subscription.
- After cancelling. Pro features remain available until the end of the period you have already paid for. The app then returns to the free version with your logged data intact.
- Refunds. Refunds are handled by Apple or Google under their own policies, not by us. We cannot issue or reverse a store charge, though we are happy to help you contact them.
4. Not medical advice
Sipster is a general wellness and habit tool. It is not a medical device and does not diagnose, treat, cure or prevent any condition. Its goals, suggestions and warnings are informational only and are not a substitute for professional advice.
The right fluid intake differs from person to person and depends on your body, health, medication, activity and climate. Drinking substantially more water than your body needs can be harmful, and the app's warnings are not a safety guarantee. If you have a medical condition, are pregnant, take medication that affects fluid balance, or have any concern about your hydration, consult a qualified professional and follow their guidance over anything in this app. In an emergency, contact your local emergency service.
5. Reminders are best-effort
Reminders are scheduled by your device's operating system. Battery savers, Do Not Disturb, force-quitting the app, revoked notification permission and system power management can delay or suppress them. We cannot guarantee that any individual reminder will be delivered at an exact moment, and you should not rely on Sipster where a missed reminder would matter medically.
6. Your data is your responsibility
Because Sipster stores your history on your device, that copy goes with the device. Uninstalling the app, wiping the phone, or losing it deletes your logs, and we cannot recover them for you — we never had them. Pro includes CSV export; use it if your history matters to you.
7. Acceptable use
Don't use the app unlawfully; don't attempt to breach, probe or overload our systems; don't attempt to obtain Pro features by circumventing the store's purchase process; and don't send abusive, unlawful or infringing content through the in-app support channel. We may suspend access where these terms are broken.
8. Availability and changes
The app and its server-side features are provided as-is and may change, be interrupted or be withdrawn. Some features depend on services we do not control (Apple, Google, and our hosting provider) and can fail with them. We may add, change or remove features between versions.
9. No warranty
To the fullest extent permitted by law, Sipster 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 its calculations are accurate for your circumstances.
10. Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, for lost data, or for any health outcome arising from your use of the app. Where liability cannot be excluded, our total liability is limited to the greater of the amount you paid us for the app in the twelve months before the claim, or USD $25. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you, and nothing here limits liability that cannot lawfully be limited.
11. Termination
You may stop using the app at any time by deleting it. We may terminate this licence if you materially breach these terms. On termination your right to use the app ends; sections that by their nature survive (liability, disclaimers, governing law) continue to apply.
12. Governing law
These terms are governed by the laws of the State of Illinois, USA, without regard to its conflict-of-laws rules, and the state and federal courts located in Illinois have exclusive jurisdiction — except where the law of your country of residence gives you the right to bring proceedings locally, which these terms do not remove.
13. Changes to these terms
We may update these terms; the current version always lives at this URL with its date. Continuing to use the app after a change means you accept the updated terms.
