Download FactaLog

System requirements

• Windows 10 (version 1809 or later) or Windows 11
• Microsoft Edge WebView2 Runtime, which is included with Windows 11 and current Windows 10; the installer downloads it if missing.
• About 25 MB of disk space for FactaLog itself, plus room for your logbook and its images.
• FactaLog uses about 500 MB of RAM while it is running. We suggest 4 GB or more, so you have room for your other programs.
• No internet connection needed to use the free logbook. Pro features need one for licence checks and sync.

macOS and Linux versions are not available yet. Email [email protected] with the system you use. It helps us decide what to build next.

Installing

1. Run the downloaded .msi and follow the installer.
2. Open FactaLog from the Start menu. Your logbook is created automatically, and there is nothing to sign in to.
3. Create a client and project, then press Ctrl+N to write your first entry.

The installer is code-signed by our company. To check, right-click the downloaded file → Properties → Digital Signatures: the signer is shown as Factalog Limited, verified by Microsoft. You can also compare the file against the published SHA-256 checksum.

Updates

FactaLog checks for updates when it starts and tells you when one is available; nothing is installed without your confirmation. Each update is signed and verified before it installs. What's new in each version is shown in the app after updating, under Settings → What's New.

Help and troubleshooting

Email [email protected]. Support is available on both the Free and Pro plans. Include your FactaLog version (shown in Settings) and what you were doing when the problem happened.
