Privacy Policy
SipSense — Hydration Coach
This Privacy Policy explains what information SipSense ("the App," "we," "us") collects, how we use it, and the choices you have. SipSense is developed by Opia Prosper.
By using SipSense, you agree to the collection and use of information as described here. If you don't agree, please don't use the App.
1. Information we collect
SipSense does not require you to create an account with an email or password. Instead, a private account is created automatically on your first launch, tied to your device and your subscription. We collect the following categories of information:
| Category | What it includes |
|---|---|
| Hydration profile | Biological sex, body weight, activity level, climate, hydration goal, and the obstacle you select during onboarding — used to calculate your personalized daily hydration target. |
| Hydration logs | The water amounts and times you log in the App. |
| Apple Health data | With your explicit permission, SipSense reads your recent workouts, sleep, and step count from Apple Health to personalize your reminders and daily goal, and writes the water amounts you log back to Apple Health so your hydration stays part of your overall Health data. |
| Subscription data | Your subscription status and a randomly generated purchaser ID, handled through Apple's In-App Purchase system and our subscription-management provider, RevenueCat. We never see or store your payment details — Apple processes all payments directly. |
| Push notification token | A device token used to deliver reminders and account-related notifications through Firebase Cloud Messaging (Google). |
| Technical data | Basic device and diagnostic information (e.g. device timezone, app version) needed to make the App function correctly, such as scheduling reminders at the right local time. |
2. How we use your information
- To calculate and continually personalize your daily hydration goal and reminder schedule.
- To sync your logged water intake with Apple Health, if you've enabled that permission.
- To operate your subscription — confirming your entitlement and restoring purchases across devices.
- To send you reminder and account-related push notifications, if you've allowed notifications.
- To maintain, secure, and improve the App.
3. Apple Health data specifically
Any data we read from or write to Apple Health is used solely to power SipSense's own features — personalizing your hydration goal and syncing your logged water intake. In line with Apple's requirements for HealthKit:
- We do not use your Health data for advertising, marketing, or any purpose unrelated to the App's core hydration features.
- We do not sell your Health data, or share it with data brokers or advertising platforms.
- You can revoke SipSense's access to Apple Health at any time in iPhone Settings → Privacy & Security → Health → SipSense.
4. Who we share information with
We do not sell your personal information. We share limited data only with the service providers that help us run the App, each of which processes data under its own privacy policy:
- Apple — processes all subscription payments and, if enabled, stores your synced Health data on your device and in your personal iCloud/Health data.
- RevenueCat — manages subscription status and entitlements on our behalf. See RevenueCat's Privacy Policy.
- Google Firebase — delivers push notifications. See Firebase's Privacy Policy.
- Our own backend server, which stores your hydration profile and logs so they sync across sessions.
We may also disclose information if required by law, or to protect the rights, property, or safety of SipSense, our users, or others.
5. Data retention
We retain your hydration profile and logs for as long as your account is active, so your history and streaks stay intact. If you'd like your data deleted, contact us using the details below and we'll delete your account and associated data, typically within 30 days.
6. Your choices
- Health data: revoke access anytime in iPhone Settings → Privacy & Security → Health.
- Notifications: disable anytime in iPhone Settings → SipSense → Notifications.
- Subscription: manage or cancel anytime in iPhone Settings → [Your Name] → Subscriptions.
- Account deletion: email us (below) to request deletion of your account and all associated data.
7. Children's privacy
SipSense is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we'll delete it.
8. Security
We use reasonable technical and organizational measures to protect your information. No method of transmission or storage is 100% secure, so we can't guarantee absolute security.
9. International users
Your information may be processed on servers located outside your country of residence, including in the United States, wherever our service providers operate.
10. Changes to this policy
We may update this Privacy Policy from time to time. If we make material changes, we'll update the "Last updated" date above. Continued use of the App after changes means you accept the updated policy.

Terms of Use
SipSense — Hydration Coach
These Terms of Use ("Terms") govern your use of the SipSense mobile application ("the App"), provided by Opia Prosper ("we," "us"). By downloading, accessing, or using SipSense, you agree to these Terms. If you don't agree, please don't use the App.
1. The service
SipSense helps you build a hydration habit through a personalized daily water goal, adaptive reminders, streak tracking, and Apple Health integration. Features that rely on adaptive reminders or Apple Health sync require the relevant permissions to be granted on your device.
2. Not medical advice
3. Subscriptions and billing
SipSense is offered through auto-renewing subscriptions (Weekly and Annual plans), managed entirely through your Apple ID. Current pricing for each plan is shown in the app and at checkout via the App Store before you ever pay.
- Payment is charged to your Apple ID account at confirmation of purchase.
- Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period.
- Your account will be charged for renewal within 24 hours prior to the end of the current period, at the price of the selected plan.
- You can manage or cancel your subscription anytime in iPhone Settings → [Your Name] → Subscriptions, or via the App Store.
- Any unused portion of a free trial period, if offered, is forfeited when you purchase a subscription.
- Refunds are handled by Apple in accordance with Apple's own refund policies — we don't have the ability to issue refunds directly.
4. Your account
SipSense creates a private, device-linked account for you automatically — no email or password is required. You're responsible for keeping your device secure, since access to the App on your device is what secures access to your account.
5. Acceptable use
You agree not to: reverse-engineer or decompile the App beyond what's permitted by law; use the App for any unlawful purpose; interfere with or disrupt the App's servers or networks; or attempt to gain unauthorized access to any part of the App or its systems.
6. Apple Health data
If you enable Apple Health integration, SipSense reads and writes data through Apple's HealthKit framework strictly to power the App's own features. See the Privacy Policy above for details on how this data is used. You can revoke this access anytime in iPhone Settings → Privacy & Security → Health.
7. Intellectual property
The App, including its design, graphics, and content (excluding your own logged data), is owned by us and protected by copyright and other intellectual property laws. You're granted a limited, non-exclusive, non-transferable license to use the App for your personal, non-commercial use.
8. Disclaimer of warranties
The App is provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose. We don't guarantee the App will be uninterrupted or error-free.
9. Limitation of liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the App.
10. Termination
We may suspend or terminate your access to the App if you violate these Terms. You can stop using the App and cancel your subscription at any time as described above.
11. Changes to these Terms
We may update these Terms from time to time. If we make material changes, we'll update the "Last updated" date above. Continued use of the App after changes means you accept the updated Terms.
12. Governing law
These Terms are governed by the laws of Nigeria, without regard to conflict-of-law principles.

This is Apple's standard EULA territory too — if you'd rather not maintain custom Terms, App Store Connect lets you use Apple's Standard EULA instead. This page exists so the language matches SipSense's actual features (Health sync, subscriptions) more specifically.
