Introduction
ClipDoggy ("we", "our", or "the app") is a clipboard synchronization application that lets you share text and images between your Mac and Android devices. We are committed to protecting your privacy and being transparent about how we handle your data.
This Privacy Policy explains what information we collect, how it is used, who it is shared with, and the choices you have.
Sync Modes and Data Flow
ClipDoggy uses Cloud Sync as its active synchronization path. Clipboard content is encrypted on the sending device before it is uploaded through Firebase (Cloud Firestore + Cloud Storage + FCM) and is decrypted only on recipient devices.
Information We Collect
1. Account Information
- What: Email address and display name (from Google Sign-In), unique account identifier
- Why: To authenticate you and link your devices
- Where: Stored in Firebase Authentication and Cloud Firestore (Google LLC, US region)
2. Device Information
- What: Device name, device type (Mac/Android), OS version, a stable device identifier (Settings.Secure.ANDROID_ID on Android; hardware UUID on Mac), Firebase Cloud Messaging (FCM) push token
- Why: To identify your registered devices, deliver wake-up notifications, and enforce the 3-device-per-account limit
- Where: Cloud Firestore + locally on each device
3. Clipboard Content
- What: The text, image, or file you choose to sync
- How it is protected: Encrypted on your device using AES-256-GCM. The symmetric key is wrapped separately for each recipient device using standard RSA-OAEP with the digest supported by that device's secure key store (SHA-256 on Mac and Android 15/API 35+, SHA-1 on Android API 23-34). Private keys remain in the recipient device's secure storage (Android Keystore / Apple Keychain).
