Privacy policy (UOTinker)
UOTinker works on your own files and does not collect, store or transmit personal data. The only
exception is the update check at start (can be switched off in the settings menu): the program asks the
GitHub API for the latest release, and GitHub receives your IP address and the user agent
UOTinker/<version> like with any web request. Settings and backups stay on your computer
in %APPDATA%\UOTinker; your client files are never sent anywhere. The installer works per user
