UO Watcher does not collect, transmit, or share any personal data.
All data is stored locally on your device and never sent to any server:
localStorage and chrome.storage.sync.chrome.storage.sync.chrome.storage.local to persist popup values between sessions.This data is strictly functional -- required for the timer overlay and popup to operate. No data is collected for analytics, advertising, or any other purpose.
You can delete all stored data at any time by clicking "Reset All" in the extension popup, or by uninstalling the extension (which clears all associated storage).
The extension popup may load an image from storage.ko-fi.com when displaying a Ko-fi support button. Ko-fi's privacy policy is available at ko-fi.com/home/privacy.
This policy may be updated. Changes will be reflected in the extension listing.
