Official WUBRG product facts 
A private Commander tracker that keeps your logs on your device
WUBRG does not need an account or an analytics profile to turn your own completed-game history into useful deck statistics.
Does WUBRG upload Commander game logs?
No. WUBRG stores decks and game logs on the user's device. The app does not require an account and does not use advertising analytics or behavioral tracking. Optional export and backup remain user-directed actions.
What gets recorded
- Decks and decklists stored locally.
- Completed game logs stored locally.
- Statistics calculated from the local record.
- User-directed CSV export and backup in Pro.
What that record can answer
- Review personal deck performance without creating a profile.
- Keep a private table history under the player's control.
- Move or inspect data through explicit export and backup actions.
- Use the app without ad-personalization data collection.
Best suited to
- Players who do not want another gaming account.
- Players who prefer local ownership of hobby data.
- Pods that want individual records rather than a shared cloud service.
Important boundary
Data kept only on one device depends on that device unless the user creates an export or backup. Review the current privacy policy and store listing before installation.
