SHA-256 checksums

Connect the browser

Install the PrivCloud browser extension. Keep its exact ID from chrome://extensions or edge://extensions.

Install the extension

Install for your user

Download and review the script, then run it without sudo. It installs Companion in your home folder and configures startup.

sh ./install-linux-dev.sh

Register your extension

Replace YOUR_ID with the exact extension ID, then reload the browser.

PRIVCLOUD_CHROME_EXTENSION_ID=YOUR_ID sh "$HOME/.local/share/privcloud-companion/register-native-messaging.sh"

Check that it works

Return to Integrations, select Refresh and check that the extension and Companion are detected. Sign in and try importing a small WebDAV file using a revocable app password.

Need help?

If Companion is missing, check Node.js, the launcher path and the extension ID, then reload the extension and PrivCloud. After an NVM update, configure the Node.js path again. A Flatpak browser may need explicit access to the Companion folder.
