Privacy Policy

Welcome to WaterCue! This privacy policy explains our policies regarding the collection, use, and protection of your personal data.

1. Data Collection & Privacy Protection

Our App is a purely local application. We value your privacy highly and do not actively collect, store, or transmit any of your personal identity information, health data, location information, or usage history.

2. Local Data Storage

All configuration data regarding your water logs, hydration targets, cup shapes, and reminder times are stored directly on your personal iOS device (using SwiftData for encrypted sandbox storage).

3. iCloud Sync Explanation

When you manually enable "iCloud Sync" in the settings, your water log data will be synchronized across multiple devices bound to your personal Apple account via Apple's official iCloud (CloudKit) platform.

We do not have our own cloud servers, so we cannot access, read, view, or modify any of your data synced to iCloud. You can turn off this feature at any time through the iOS system settings and delete the corresponding backup from the cloud.

4. Permission Usage

• Notification permission: Only used to send local push notifications to remind you to drink water within the time window you set. We never use this permission to collect information or push commercial advertisements.

5. Third-party SDKs & Tracking

Our App does not integrate any third-party advertising, analysis, or tracking SDKs, and will never track your network activity in the background or share any data with third parties.

6. Changes to Privacy Policy

We may update this privacy policy from time to time. The updated privacy policy will take effect once published.
