Heads-up on first launch

Sery Link isn't code-signed by Apple or Microsoft yet (Developer enrollment is in progress). The OS will warn on first launch — once you allow it, future launches and auto-updates work normally.

macOS — “is damaged”: if you see “Sery Link is damaged and can't be opened”, despite the wording the app isn't damaged — macOS shows this for any downloaded app that isn't Apple-notarized. Strip the quarantine attribute in Terminal:
xattr -dr com.apple.quarantine /Applications/Sery\ Link.app
One-time fix per install. The app then opens normally.
macOS — “cannot be opened”: a milder variant. Open System Settings → Privacy & Security, scroll to Security, click “Open Anyway” next to the Sery Link entry. Or right-click the app → Open → confirm.
Windows: SmartScreen will say “Windows protected your PC”. Click More info → Run anyway.
Linux: no warning. AppImage needs chmod +x before running.

Read every private document on your machine

PDFs (incl. scans via OS-native OCR), DOCX, PPTX, XLSX, CSV, Parquet — all read in-process via a native Rust toolkit (pdfium / Vision / calamine / Pandoc). Connect nine storage protocols (Local, HTTPS, S3, Drive, SFTP, WebDAV, Dropbox, Azure, OneDrive) plus B2 / Wasabi / R2 / GCS. Local features work fully offline. Pair multiple machines into one private workspace — documents never leave the device they live on.
