History without the cloud.
Native filesystem events capture changes while compressed, deduplicated recovery data stays in Local Core's local application storage.
Built for recovery.
Browse retained versions and restore regular file contents, with safeguards designed to preserve the file being replaced when possible.
How it works
Choose a folder.
Local Core handles the history.
No sync folder. No manual snapshots. Protect ordinary folders already on your PC and keep working as usual.
Select what matters.
Add the folders you want Local Core to protect. Missing or unavailable roots are handled conservatively rather than treated as mass deletions.
Keep working normally.
A native filesystem watcher observes changes. Local Core stores deduplicated recovery points locally according to retention, quota, and Safety Reserve policies.
↶
Go back when needed.
Preview retained history and restore a previous regular-file version. Local Core attempts a recovery point of the current file before replacing it.
Local-first privacy
Your files are the product.
Not the data source.
Local Core's Time Engine works on-device. The beta does not require a cloud service for monitoring, history, preview, or restore and does not include product telemetry or analytics reporting.

Safety Reserve
Free-space protection takes priority.
Local Core keeps quota and Safety Reserve separate. When free disk space is under pressure, the reserve wins.
Default reserve: max(20 GB, 10% of disk capacity)
Unavailable folders
A missing drive is not a deleted folder.
Unavailable or unreadable protected roots are isolated so healthy roots can continue, while Local Core avoids inferring false file deletions.

Before installing: This is pre-release software and must not be your only backup. Keep an independent backup for important files, and review the Known Issues before relying on the beta.
FAQ
Does Local Core upload my protected files?
No. The current Time Engine does not intentionally upload protected file contents, recovered versions, filenames, or version history to a Local Core service.
Is Early Access free?
Yes. The first Windows Early Access beta is free for evaluation and testing under the published Beta Terms.
Why is the Windows beta unsigned?
We are validating product interest and real-world behavior before paying for production signing infrastructure. The exact installer SHA-256 is published in the download section above.
Is Local Core a replacement for a backup?
No. During beta, keep an independent backup strategy appropriate to the importance of your data.
