AirSync Pro: Sync & Backup

AirSync Pro — Professional File Sync for Android

AirSync Pro is a powerful, security-first file synchronisation app for Android users who demand full control over their data. Whether you're backing up to a NAS, running your own SFTP server, or syncing between local folders, AirSync Pro keeps everything in sync — automatically, securely, and intelligently.

Multiple Sync Backends Connect to local or USB folders, SMB network shares (NAS, Windows, Samba), or any SFTP server over SSH. Each sync node is fully independent, so you can run multiple active pairs simultaneously — backing up photos to your NAS while mirroring documents to a remote server at the same time.

Flexible Data Flow Choose how data moves: local-to-remote, remote-to-local, or full bi-directional sync. Conflict resolution is configurable — newest wins, source wins, destination wins, or manual review with AI-assisted recommendations explaining which version is likely correct.

End-to-End Encryption Files are encrypted on-device before transfer using AES/CBC with a unique IV per file. Keys are managed per sync node, so even a compromised server can't read your data. E2EE works across all three backends with no extra setup.

Smart Transfer Engine Delta Sync computes SHA-256 hashes before transferring, skipping unchanged files to save bandwidth. Chunked Transfer stages uploads to a .part file and atomically renames on completion, so destinations never receive incomplete files. Deep Scan verifies integrity with a full hash comparison after every transfer to catch corruption before it reaches your destination.

AI and Intelligence Neural Predictive Sync analyses your sync history — average intervals, peak activity hours, and file-change velocity — to recommend schedule adjustments. Anomaly Detection alerts you if an unusually high proportion of destination files are being overwritten. Smart Content Categorisation automatically sorts synced files into Photos, Videos, Documents, Archives, Music, and Apps subfolders.

Automation and Scheduling Restrict syncs to Wi-Fi only, require charging, or pause below a battery threshold. Bandwidth throttling caps upload speed to protect other network activity. Exclusion patterns support wildcards. Connection-drop detection saves a checkpoint mid-sync so the next run resumes exactly where it left off.

Security and Access Control Lock individual nodes behind biometric authentication. VPN Policy can require or block a VPN connection per node. A full audit log tracks every action across all nodes. Wake-on-LAN wakes sleeping servers before scheduled syncs begin.

Web Access and Performance Enable Web Access to serve your sync folder over a local HTTP or HTTPS server, browsable from any device on the network. Three profiles — Turbo, Balanced, and Battery Saver — tune buffer sizes and parallelism to match your priorities.

AirSync Pro delivers enterprise-grade sync with no subscriptions, no cloud middlemen, and no compromise
