Ublok does not collect, store, transmit, or sell any personal data. All blocking and filtering happens locally on your device. Ublok does not track your browsing, does not use analytics, has no accounts, and
sends no data to us or any third party. The only network requests Ublok makes are to download public ad/tracker filter lists (such as EasyList and uBlock Origin lists) so it can keep your protection up to date. These requests fetch filter data only and contain no information about you or the sites you visit. Your settings (such as which sites you've disabled) are stored locally in your browser and never leave your device.
