Windows 10/11 & Linux · Chromium browsersDownload FURSOY Vault.
FURSOY Vault protects selected signed-in browser sessions by removing their cookies from the browser, storing them in an encrypted vault on your own machine and restoring them only after you explicitly approve.
Each stable link always resolves to that platform's companion from the latest published GitHub release. The browser extension is installed separately, from the Chrome Web Store.
What the download contains
The companion app that holds the vault. It communicates only with the FURSOY Vault extension, through the browser's Native Messaging channel, and never over the network. On Windows the Setup executable also installs a safe automatic updater, which applies later companion updates only when no protected operation is active; on Linux the companion is updated the way everything else on the system is, by the package manager.
Requirements and installation
A Chromium browser — Chrome, Edge, Brave or similar — and a machine with a TPM 2.0 security chip, which most from the last several years have.
Windows 10/11: the account needs a Windows Hello method configured. Run FURSOY-Vault-Setup.exe; Windows may show an Unknown publisher warning because the installer is currently unsigned. Uninstall through Installed apps.
Linux: extract the archive and run the included register.sh. You choose a PIN the first time a vault opens, and the TPM holds it. Run unregister.sh to remove it.
On both, removing the vault data itself stays an explicit choice rather than something uninstalling does for you.
Verify the download
Each GitHub release publishes a .sha256 file next to every download. Compare that SHA-256 checksum before installing. The release page identifies the corresponding source tag and build procedure.

The Windows companion installer is currently distributed without an Authenticode signature and may appear as Unknown publisher. Linux has no equivalent prompt, but the same checksum verification applies there. Download it only from the official GitHub Releases page and compare the installer against the adjacent SHA-256 checksum before installation.
Every public package is built and tested by the project's GitHub Actions workflow from its matching source tag. If trusted code signing is introduced later, this page and the release policy will be updated before the first signed release.
