How does Ugly Email work?

Ugly Email scans through your inbox and looks for emails containing tracking pixels. Tracked emails are labeled with an eyeball(Ugly Email Icon) icon, and the tracking pixel is blocked.

Where is my data stored?

All of the Ugly Email data is stored on your browser's IndexDB storage locally. We do not track, transfer, or store any of your information.

Does Ugly Email work on mobile?

Ugly Email does not work cross-platform. As mentioned above, all detection is done locally on your desktop browser. We also do not alter your emails nor permanently strip the tracking pixels. We block them.

I found a bug, what should I do?

Please report any bugs you find in Ugly Email by either opening an issue in Github. Bug reports from users are the primary means of quality assurance.
