BazaarHub Tracker
Records your runs of The Bazaar while you play and puts them on your BazaarHub profile, every hour of every run. Free, with no ads.
Set up on Windows
Install the tracker
Run the installer you downloaded. If Windows says Windows protected your PC, press More info, then Run anyway. It asks because the tracker isn't signed with a paid certificate yet, and updates won't ask again.
A short welcome sets it up, and from then on it starts with Windows and waits in the tray.
Connect your account
Make a key here and press Open in the tracker. It fills the key in and shows your account name to confirm.
Play a run
Start a game from Steam or the Tempo Launcher. The tracker's Game row turns teal, and each run reaches your profile hour by hour while you play.
Set up on a Mac
Install the tracker
Open the disk image and drag BazaarHub Tracker into Applications, then open it. macOS checks it three times, because the tracker isn't notarised with Apple yet:
Press Done, not Move to Bin. 
In System Settings, Privacy and Security, scroll to Security and press Open Anyway. 
Press Open Anyway again and use your password or Touch ID. Connect your account
Make a key here and press Open in the tracker. It fills the key in and shows your account name to confirm.
Play a run
Start the game from Steam. The first time, macOS asks once to let BazaarHub Tracker read it. Approve it, and the Game row turns teal. Until then it says Waiting for permission.
On a Mac account without admin rights, macOS asks for an administrator's password again every 10 hours.
