Does Lyndesk require an internet connection to run or bill transactions?
No. Lyndesk is 100% offline-first. All records, inventory data, customer ledgers, and audit trails are written directly to your local SQLite Write-Ahead Log (WAL) database on disk. An internet connection is never required for counter operations, barcode scanning, or thermal printing.
Where is my business data stored on my computer?
On Linux: ~/.local/share/lyndesk/lyndesk.db (along with lyndesk.db-wal and lyndesk.db-shm). On Windows: %APPDATA%\lyndesk\lyndesk.db. You own this file completely; you can back it up, copy it to an external drive, or inspect it with any standard SQLite viewer.
How do I back up and restore my database?
To back up, simply make a copy of the lyndesk.db file when the application is closed: 'cp ~/.local/share/lyndesk/lyndesk.db ~/backups/lyndesk-backup-$(date +%F).db'. To restore, replace the lyndesk.db file in that directory with your backup.
Which receipt printers and barcode scanners are supported?
Lyndesk supports standard ESC/POS 80mm and 58mm thermal printers over USB, RS-232 serial, Bluetooth, and raw TCP/IP (port 9100). Any standard USB or Bluetooth HID barcode scanner works automatically out-of-the-box as a keyboard wedge.
How does offline commercial license activation work?
Commercial licenses purchased from wintershogun.tech are perpetual cryptographic keys. When entered into Lyndesk, the software validates the signature mathematically offline using our embedded public key. No phone-home telemetry or cloud activation server is ever contacted.
How do I update or uninstall the Linux Community Edition?
To update, simply re-run the one-line installer: 'curl -fsSL https://raw.githubusercontent.com/chronoarchon/lyndesk/main/install.sh | bash'. It will safely replace the binary in ~/.local/bin/lyndesk without touching your database in ~/.local/share/lyndesk. To uninstall, delete ~/.local/bin/lyndesk and ~/.local/share/applications/lyndesk.desktop.
