Two-way sync between your PC and the cloud, built for privacy and speed.
Trusted by people who care about their files
Powerful where it counts, invisible where it doesn't.
Change a file anywhere - on your PC or in the cloud - and SyncLine keeps both sides identical. Smart conflict handling that never loses data, ever.
Runs 100% on your PC with encrypted local state. No servers, no middleman - your data is yours.
A high-performance engine streams changes so huge folders sync smoothly without slowing your PC.
Real-time upload and download activity, plus a clean log of every success, in-progress task, and failed state - always at a glance.
Pause and resume syncing anytime. Choose exactly which folders sync, with automatic system-folder protection built in so nothing critical is ever touched without your say-so.
Three simple steps and you're syncing.
Connect OneDrive or Google Drive using Microsoft's and Google's own secure sign-in screens. SyncLine never sees your password - ever.
Choose exactly which folders on your PC keep in sync with the cloud. You stay in full control of what moves where.
SyncLine runs quietly in the background, keeping everything up to date without lifting a finger. Set it and forget it.
Start free. Upgrade when you're ready.
Pro is purchased via the Microsoft Store; both plans unlock the same Pro features.
Your files never pass through us. That's a promise, not a feature.
Files move directly between your PC and your cloud provider. No SyncLine servers are ever in the path - we don't have any. No account with us required.
All local sync state is encrypted using Windows Data Protection (DPAPI), tied to your Windows user account. Only you can read it.
Sign-in happens via Microsoft's and Google's own secure consent screens. SyncLine uses their official OAuth flow - your credentials never touch our code.
We don't run telemetry servers. The app design is transparent and auditable - no hidden data collection, no silent background calls home.
