Privacy Policy

Effective: September 25, 2026

1. Local-first identity

MA can be used without creating a conventional server account. The app creates a pseudonymous cryptographic identity on your device. Your local identity key, nickname, optional locally saved email address, contacts, chat history, preferences, and other app state are primarily stored on your device.

2. Information processed to provide MA

Information stored on your device

• Cryptographic chat identity keys and identity address; wallet keys, public wallet addresses and local transaction records when you use wallet features.
• Profile name, avatar choice, optional email saved locally, contacts, friend remarks, groups, and chat history.
• User-selected photos, voice messages, preferences, security settings, game state, and contribution/mining state.

Information transmitted off your device

• Messaging and social features: identity addresses, signed profile information, friend and group requests, message payloads, selected media, delivery information, and presence may be routed through AstroBridge nodes to provide messaging and offline delivery.
• Network operations: IP address, connection time, node selection, device/app version, diagnostic status, and routing metadata may be processed for connectivity, abuse prevention, reliability, and security.
• Voice calls: call-signaling metadata is routed through AstroBridge. WebRTC media may flow directly between participants or through TURN/media servers, depending on connectivity and the calling mode. Hosted voice-room servers process media to deliver the room; hosted rooms are not represented as end-to-end encrypted. MA does not intentionally record call audio. Peer-to-peer connections can reveal participants' IP addresses to one another.
• Contribution/mining feature: a device installation identifier, pseudonymous identity address, signed session records, friend proofs, activity counts, heartbeat times, and anti-abuse metrics are sent to AstroBridge to determine eligibility and maintain contribution records.
• Safety reports: when you report a user or message, MA sends the reported pseudonymous identity, report reason, conversation/message identifiers, and a limited excerpt of the selected content to AstroBridge for safety review. Reports never include your private key, recovery phrase, or password.
• Wallet and blockchain services: public wallet addresses, selected networks and assets, balance/history queries, quote requests and signed transaction data may be sent to blockchain RPC providers and AstroBridge services when you use those features. Public blockchains publish and retain transaction records independently of MA. Support does not need your private key or recovery phrase.
• External content: when you play online Bible audio in MA full or visit a website in either edition's browser, that content provider receives ordinary web request information such as your IP address and browser/device information under its own privacy policy.

3. Purposes

We process information only to provide requested app functions, route communications, synchronize offline messages, connect calls, operate contribution features, maintain security, prevent abuse, diagnose failures, and comply with law. We do not sell personal data and do not use MA data for third-party behavioral advertising.

4. Permissions

• Camera: scan QR codes and capture content you choose.
• Photos/media: select an image to send, post, or use as an avatar.
• Microphone and audio: voice messages and voice calls.
• Notifications: alert you to messages or calls.
• Biometrics: optional on-device protection; MA does not receive your fingerprint or face template.
• Bluetooth: support connected audio devices during calls.

5. Storage, retention, and deletion

Local data remains on your device until you clear it, switch local identities, or uninstall MA. Operational and offline-delivery data handled by AstroBridge is retained only as reasonably necessary to deliver the service, secure the network, resolve abuse, and meet legal obligations. MA's locally created identity is not a conventional online account. You can remove local app data from MA settings and your operating system. You may also request deletion of server-side data reasonably associated with your pseudonymous identity by following our data deletion instructions.

6. Security

Before clearing app storage, switching accounts or uninstalling, securely back up any wallet recovery information you need. Removing wallet keys without a recoverable backup can permanently prevent access to funds. Deleting app or server records cannot erase public blockchain transactions or copies of messages held by other participants. Confirmed blockchain transfers cannot be cancelled by MA or AstroBridge; check the recipient, network and asset before signing.

MA uses encrypted network transport and signed cryptographic identities. Sensitive local data is intended to remain under the user's control. No internet service or device storage method is completely secure; users should protect their device and never share private keys or recovery phrases.

7. Children

The MA and MA full Google Play editions are intended for users aged 18 and over and are not directed to children.

8. Changes and contact

We may update this policy as MA changes. The effective date above will be revised when material changes are made. Questions and privacy requests may be sent to baow59671@gmail.com.
