Introduction

Catdog (hereinafter "we", "this app", or "the app"; package name com.muxijinnian.catdog) attaches great importance to user privacy. This privacy policy explains in detail how we collect, use, protect, and share your information. By using this app, you agree to the terms of this privacy policy.

This app is an Android tool that lets users play cat and dog sounds, enjoy fun interactions, and manage pet profiles. We are committed to providing a safe and transparent service experience.

1. Information We Collect

1.1 Device & Advertising Data

This app integrates Google AdMob to keep the app free. To serve ads, Google may automatically collect the following information:

• Device identifiers: e.g. advertising ID (Google Advertising ID), for ad delivery and frequency control
• Device & app info: device model, OS version, app package name and version, language, screen size, etc.
• Ad interaction data: impressions, clicks, dismissals, completion of ads
• Approximate location: country/region-level location inferred from IP address (not precise to individuals)
• Usage data: general interaction data to improve ad relevance

This information is collected and transmitted by Google through its SDK; this app does not intercept or store it on its own.

1.2 Locally Stored Data

The app stores the following data, which you enter actively, locally on your device (using a built-in database):

• Pet profiles: nickname, birthday, sex, pet type (cat/dog), and breed of pets you add
• App settings: local counters such as feature usage counts

1.3 Microphone Permission

This app requests the microphone permission (RECORD_AUDIO) for voice-interaction features such as "human speak" and "cat speak" to record sound for the interaction. Please note:

• Recordings are used only for local processing (e.g. voice-interaction effects) and are never uploaded to any server;
• We do not retain your recordings long-term; they are discarded or overwritten once local processing is complete;
• You may revoke this permission at any time in system settings. Revoking it only affects voice-interaction features; other features remain available.

2. How We Use Information

We and third-party services collect and use information for the following purposes:

• Provide core services: normal operation of sound playback, pet management, etc.
• Ad delivery: display ads via AdMob to keep the app free
• Improve services: fix defects, optimize performance, improve experience
• Security & compliance: prevent abuse and meet legal requirements

We do not sell, rent, or trade your personal information. Information may be shared in the following cases:

• Service providers: necessary information shared with ad providers such as Google (see Section 3)
• Legal requirements: disclosure of necessary information when required by law

3. Advertising Policy (Google AdMob)

This app uses Google AdMob to display ads (including app-open ads, banner ads, rewarded video ads, etc.). Google may use cookies or similar technologies to collect information for ad delivery.

• Personalized ads: may show relevant ads based on your interests and app usage
• Ad identifiers: uses the advertising ID for ad tracking and frequency control

You can control ads via:

• Resetting the ad ID or enabling "Opt out of Ads Personalization" in Android system settings (Limit Ad Tracking)
• Managing personalized ads at Google Ads Settings

For details on how Google uses ad information:

• Google Privacy Policy
• AdMob Data Safety guidance

4. Data Security

We take reasonable measures to protect your information:

• Local data: pet profiles are stored only on the device and never uploaded to a server
• Encrypted transmission: network communication of the ad SDK uses HTTPS
• Cleartext restricted: the app blocks cleartext (HTTP) network traffic

However, please note that no internet transmission or storage method is 100% secure.

5. Your Rights

You have the following rights regarding your data:

• Access & correction: view and edit your pet profiles in the app
• Right to delete: delete pet records in the app, or uninstall the app to clear all local data
• Permission control: grant or revoke permissions such as the microphone at any time in system settings
• Ad control: limit personalized ads via system ad settings

To request deletion or to object to data processing, please contact us as described in Section 7.

6. Children's Privacy

This app is suitable for users of all ages and is mainly aimed at pet lovers. We do not knowingly collect personal information from children under 13. As the app does not collect personally identifiable information and complies with requirements for apps that may appeal to children, any inadvertently collected children's information will be deleted immediately.

For parents: you can manage your child's app usage and permissions through device settings.
