After downloading, run DataOS-Setup-1.0.0.exe and follow the wizard. The installer has passed clean-machine installation acceptance and security scanning.

📋 Download notice (please read first)
This installer is not yet Microsoft code-signed (signing is in progress), so Edge / Chrome may show a "DataOS-Setup-1.0.0.exe isn't commonly downloaded" prompt. This is a browser reputation notice for new software, not a virus warning. If you see it:
① Click the "⋯" on the right of the prompt → "Keep" → "Keep anyway";
② Or right-click the file in the download list → "Keep";
③ To be extra careful, verify the SHA256 checksum above first (certutil -hashfile DataOS-Setup-1.0.0.exe SHA256) before running.
The prompt will disappear automatically once the code-signing certificate is issued. We apologize for the inconvenience.

Works standalone on phones and tablets: sign up, manage phone files, search on-device, play local and private-cloud videos, back up photos and files. If you also have a Windows PC, you can optionally pair with it for extra horsepower (transcoding, AI, full-library indexing) — connecting a PC is an optional enhancement, not a requirement. Signature verified with apksigner (APK Signature Scheme v2).

Install guide: ① Download the APK with your browser; ② If prompted that installs from unknown sources are blocked, follow the prompt to allow installs for this browser only; ③ Return and finish installing. No need to disable your phone's global security protection.

The macOS and iOS apps are standalone clients just like the Android app (no Windows PC required). They are in development; downloads will appear on this page as soon as they ship. We never ship placeholder buttons without real functionality.

What it does for you

🔍

Find files with one sentence

Can't remember the filename? Describe the content — document text, transcribed recordings, photo scenes are all searchable.

♻️

Free up hundreds of GB

Duplicate files and videos identified by content — even renamed ones can't hide. Clear the space-wasters.

🎬

Fix your media library

No sound, A/V out of sync, garbled subtitles, washed-out HDR, oversized 4K — one-click diagnosis and repair, originals never touched.

🗄️

Manage PC and NAS together

SMB/WebDAV sources in a unified index — one search box for everything, remote video streams without copying.

🛡️

Backups that actually restore

Incremental backup, multi-target with encryption, crash-safe resume; full recovery after a reinstall.

🔒

Privacy stays on your PC

Scanning, recognition and processing all local. Private files are never uploaded, never leave. That's the bottom line.

Release notes

  • First official release (v1.0.0): local search (filenames/tags/content), duplicate detection, image/video/audio processing, media playback with subtitle fixes, full backup & restore chain.
  • Unified management of local drives, external drives, NAS (SMB) and WebDAV sources.
  • Installer size optimized (338.6 → 267.5 MB); install and uninstall both passed real-environment acceptance.

Installation needs about 1 GB of disk space; first run guides you through adding data sources and building the local index. On uninstall you can keep or delete user data — your original media files are never deleted by uninstalling, under any circumstances.
