Privacy Policy

Last updated: 2026-01-17

This Privacy Policy applies to the Call Pet mobile app (including the monitor device and controller device). Please read it carefully. If you have any questions or wish to exercise your rights, contact us using the details below.

1. Data Controller and Contact

Data Controller: Chen Zhiguo (indie developer).

Email: support@callpet.me.

Address: Shell Haiyan Apartment, Huamao City Phase II, Shui'an South Street, Chaoyang District, Beijing, China.

2. Our Principles

• Data minimization: no accounts and no collection unrelated to the service.
• Encrypted transport: signaling and media use industry-standard encryption in transit.
• User control: pairing is user-initiated and confirmed, and local recordings are fully controlled by you.

3. Information We Process and Purposes

1. Audio and video content is transmitted only between two devices. Our servers do not receive or store media content.
2. Local recordings (optional) are stored on your device and saved to the system photo library with your permission.
3. Pairing and signaling data (session identifiers, public keys, signaling and ICE addresses) is used only to establish connections.
4. Network metadata (IP address, ports, timestamps, connection status, traffic size) may be visible to infrastructure for connectivity and security.
5. Local settings and state are stored on-device and are not uploaded.
6. Diagnostic logs are generated locally. We collect them only if you choose to send them to us.

4. Third-Party SDKs and Services

• Analytics/ads/crash SDKs: none are integrated.
• STUN/ICE services: a third-party STUN/ICE service may be used for NAT traversal.
• Signaling server: the signaling server only forwards encrypted messages and does not hold decryption keys.

5. How We Use the Information

• Provide calling, auto-answer, push-to-talk, camera switching, flashlight, and adaptive bitrate.
• Provide optional local recording and saving to Photos.
• Maintain reliability, security, and abuse prevention.

6. Data Storage and Retention

On-device data (pairing, settings, recordings) stays on your device and can be deleted at any time.

Server-side signaling does not store media content. Minimal connection logs are retained for no longer than 10 days and then deleted or anonymized.

7. Sharing

• We do not sell personal information.
• STUN providers may process network metadata for connectivity; media remains encrypted.
• We may disclose information if required by law or to protect users and the public.

8. Your Rights

You can access, delete, or reset data by managing it on your device. If you believe we hold identifiable data, contact us.

Where required by law, you may request restriction, objection, or data portability.

You can withdraw permissions in system settings, which will limit related features.

9. Permission Use

• Camera: capture video, generate QR codes, and scan QR codes.
• Microphone: capture audio and push-to-talk.
• Local network or network access: signaling and WebRTC connectivity.
• Storage or Photos: save recordings to the system photo library.
• Wake lock or foreground service (Android): keep the monitor device active.

10. Security

Signaling and media are encrypted in transit, with P2P preferred and STUN used when necessary.

If a device is rooted or compromised, or pairing codes are leaked, others may gain access. Please keep devices and pairing codes secure.

11. Children's Privacy

The app is not directed to children under 13. If you are under 13 or a minor under local law, use the app only with parental consent and guidance.

12. International Users and Legal Bases

If you are outside Mainland China, using the app may involve cross-border data processing (for example, communicating with signaling or STUN services).

For EEA, UK, or Switzerland users, our legal bases include contract performance and legitimate interests for necessary metadata, and consent for permission-gated features.

California residents: we do not sell or share personal information for cross-context behavioral advertising.

13. Policy Updates

We may update this policy for new features, legal changes, or operations. Material changes will be notified in the app where required.
