PetDrinkDiary Privacy Policy

1. Information We Process

PetDrinkDiary currently does not provide account registration, login, subscription services, advertising services, community interactions, cloud account synchronization, or developer-operated server data storage services.

When you use the App, relevant information is primarily stored locally on your device. Depending on the features you actively use and the permissions you grant, we may process the following information.

1.1 Hydration Records and App Settings

To provide hydration recording, statistics, reminders, and goal-management features, the App stores the following information locally on your device:

• Hydration time, hydration amount, beverage type, and notes;
• Daily hydration goals, information related to goal generation, and results of manual changes;
• Reminder times, reminder intervals, Do Not Disturb settings, and reminder toggle status;
• Unit, language, onboarding status, and other App preference settings;
• Personal milestones, interaction status, and related unlock records.

This information is used to provide hydration recording, statistical displays, reminders, goal suggestions, Widget displays, and normal App functionality.

1.2 Today’s Check-in Data

When you actively create a check-in record for today, the App stores the check-in date, streak information, daily hydration amount, beverage statistics, completion rate, and data needed to generate a share card locally on your device.

This data is used only for in-App display, statistics, and generating today’s check-in or personal milestone share images. It is not uploaded to developer-operated servers.

1.3 Information You Actively Provide

You may actively enter or modify certain information, such as your nickname, body weight, activity level, or other information used to generate hydration goals.

This information is stored locally on your device by default and is used to generate or adjust suggested hydration goals. You may modify this information in the App at any time.

1.4 Apple Health Data

After you actively authorize Apple Health access, PetDrinkDiary may read the following data:

• Body mass;
• Biological sex;
• Step count;
• Hydration data.

Body mass, biological sex, step count, and related information may be used to assist in generating suggested hydration goals. Hydration data may be used for synchronization with Apple Health and for displaying related hydration records and statistical information within the App.

PetDrinkDiary writes hydration records newly created in the App to Apple Health.

When you modify a hydration record linked to Apple Health, the App will attempt to update the corresponding Apple Health hydration sample if the hydration amount or hydration time changes. If you only modify the beverage type or notes, the App will not modify the corresponding hydration sample in Apple Health.

PetDrinkDiary does not write body mass, biological sex, or step count data to Apple Health.

When you delete a hydration record in the App that is linked to Apple Health, the App will attempt to delete the corresponding Apple Health hydration sample. Such synchronization, update, or deletion may not be completed due to system permissions, Apple Health status, or other system-related reasons.

1.5 Location and Weather Information

When you authorize location permission and actively generate or regenerate a hydration goal, PetDrinkDiary may obtain your current location on a one-time basis and use WeatherKit to obtain a reference for the current local temperature.

Your current location and current temperature are used only to make appropriate adjustments to suggested hydration goals, such as increasing the suggested hydration amount in higher-temperature environments.

PetDrinkDiary does not perform continuous location tracking or background location tracking. We do not store your precise coordinates, city, location history, or weather history, and we do not upload this information to developer-operated servers.

1.6 Notification Information

When you authorize notifications and enable hydration reminders, PetDrinkDiary uses iOS local notification features to send hydration reminders.

Relevant reminders are processed locally by your device system. PetDrinkDiary does not use remote push notifications and does not upload notification content or reminder times to developer-operated servers.

1.7 Camera, Photo Library, Profile Images, and Check-in Photos

You may actively choose a profile image or a photo for today’s check-in and provide an image to the App through the camera or photo library.

These images are used only for profile display, today’s check-in cards, and personal milestone share cards. Profile images are stored in the Application Support directory on your device; check-in photos are processed locally for the current card. Images are not uploaded to developer-operated servers, and the App does not maintain a remote image database.

1.8 System Sharing

When you actively tap the share button, the App invokes the iOS system sharing feature. Shared content may include your profile image, nickname, hydration data, check-in date, streak information, and a photo you selected, depending on the share card you generate.

You choose the target application. How a third-party application handles content it receives is governed by that application’s own privacy policy.

1.9 Saving Images

When you actively tap “Save Image,” the App saves the generated share image to the system photo library. The App does not save images automatically and does not create an additional copy on developer-operated servers for this purpose.

1.10 Widget and App Group Local Shared Information

When you use the home screen Widget, PetDrinkDiary locally shares necessary hydration summary information between the App and its Widget through App Group on your device, such as:

• Daily hydration amount;
• Daily goal;
• Hydration progress;
• Remaining hydration amount;
• Number of hydration records;
• Latest hydration information;
• Unit and language settings.

This sharing occurs only between the App and its Widget extension on the same device. It does not constitute providing or uploading the relevant information to third parties.

2. How We Use Information

We use relevant information only to the extent necessary to provide the following functions:

• Providing hydration recording, editing, deletion, statistics, and history-viewing features;
• Generating, updating, or displaying suggested hydration goals;
• Synchronizing hydration records created in the App with Apple Health;
• Providing local hydration reminders;
• Referencing the current temperature to adjust suggested hydration goals when you grant authorisation;
• Storing check-in data for today that you actively create for in-App display, statistics, and share-image generation;
• Generating today’s check-in and personal milestone share images and, when you actively choose to do so, invoking system sharing or saving them to the system photo library;
• Displaying Widgets, profile images, personal milestones, and interactive content;
• Maintaining the normal operation of local App features and improving the basic in-App experience.

PetDrinkDiary does not sell your personal information, use your personal information for targeted advertising or cross-app tracking, or provide it to third parties for marketing purposes.

3. Information Storage and Sharing

3.1 Local Storage

PetDrinkDiary hydration records, today’s check-in records, settings, reminder configurations, profile images, goal-related information, share-card data, and Widget summary information are primarily stored locally on your device.

PetDrinkDiary does not provide a developer-operated account system, cloud account synchronization, or developer-operated server data storage services.

Except when you actively contact us by email or use Apple system services such as Apple Health, WeatherKit, system notifications, camera, or photo library features, we do not actively transmit the above local data to developer-operated servers.

3.2 Apple Services

When you use features such as Apple Health, location, WeatherKit, system notifications, camera, photo library, or Widgets, those features are supported by Apple-provided system services or frameworks and are subject to Apple's applicable terms and privacy policies.

For example:

• Apple Health data is managed through HealthKit;
• Weather references are obtained through WeatherKit;
• Local notifications are handled by iOS;
• Camera and photo library access are controlled by iOS permission mechanisms.

3.3 Information We Do Not Share

Except where required by applicable laws or regulations, lawfully required by judicial or administrative authorities, or necessary to protect you, others, or public safety, we do not sell, rent, trade, or provide your hydration records, health-related information, location information, profile images, or other local data to third parties, except when you actively use the system sharing feature.

3.4 System Sharing and Third-Party Applications

When you actively use the system sharing feature, the App passes only the generated image you choose to share into the iOS system sharing flow, and you choose the third-party application that receives it. PetDrinkDiary does not control how a third-party application receives, stores, processes, or distributes the content.

Third-party applications’ handling of shared content is governed by their own privacy policies and terms of service.

3.5 Saving to the System Photo Library

When you actively save a share image, iOS writes the image to the system photo library on your device. PetDrinkDiary does not save images automatically and does not create an additional copy on developer-operated servers.

4. Your Controls

You may manage relevant information and permissions in the following ways:

• Edit or delete hydration records, notes, profile images, goals, and reminder settings in the App;
• Manage system permissions, such as location, notifications, camera, and photo library access, in iPhone Settings;
• Manage PetDrinkDiary's authorisation to read and write health data in Apple Health;
• Stop using the App or uninstall the App to delete most data stored locally by the App on your device.

Please note:

• Uninstalling the App will generally delete data stored locally by the App;
• Data written to Apple Health is managed by Apple Health, and you may view, modify, or delete it in Apple Health;
• System backups, Apple Health backups, and other data processing managed by Apple may be subject to Apple's applicable rules.

5. Health Information Notice

PetDrinkDiary is not a medical device and does not provide medical diagnosis, treatment advice, emergency medical services, or individualized medical plans.

Hydration goals and reminders generated by the App based on information such as body weight, activity level, step count, and environmental temperature are for daily hydration management reference only. They should not replace the advice of physicians, dietitians, or other qualified professionals.

If you have kidney disease, cardiovascular disease, metabolic disease, a condition requiring fluid restriction, special pregnancy-related circumstances, or any other condition requiring medical management, you should prioritize the advice of qualified professionals.

6. Minors

PetDrinkDiary provides daily hydration-management features for general users.

If you are a minor, please read and use the App under the guidance of a guardian. Guardians should assist minors in understanding this Policy and decide, based on actual circumstances, whether to authorize relevant system permissions.

We may update this Privacy Policy due to feature adjustments, legal or regulatory requirements, or service changes.

Updated content will be made available through an in-App entry point, relevant public webpages, or other appropriate methods, and the "Last Updated" date will be revised accordingly.

If an update may materially affect your rights and interests, we will notify you in a reasonable manner.
