Moj Ad Blocker does not collect, store, or transmit any personal data.

The extension does not have a server, an account system, or any
analytics.

All settings — the site whitelist, custom hidden element selectors,
and blocked request counters — are stored locally in the browser
using the storage.local API. They never leave your device.

Broad host permissions and webRequestBlocking are required to inspect
and block requests to known advertising and tracking domains. Request
data is evaluated in memory and immediately discarded. Nothing is
logged or sent anywhere.
