Privacy Policy

SuperBlocker is designed so neither the app nor our servers can see the URLs you visit.

What SuperBlocker collects

The SuperBlocker app does not collect, sell, or share personal information, browsing history, requested URLs, advertising identifiers, or analytics.

How filtering works

Filtering is performed by Apple’s Network Extension URL Filter. A Bloom filter handles most checks on your device. Potential matches are confirmed using encrypted Private Information Retrieval through Apple’s Oblivious HTTP relay. These protections prevent our service from learning the requested URL or associating requests with your device identity.

Service operations

Our infrastructure provider may process limited technical data needed to deliver and secure the service, such as timestamps, service health, and aggregated error information. We do not use this data to build profiles, track browsing activity, or advertise.

Third-party lists

The optional blocking data is derived from the open-source StevenBlack hosts project. Enabling a list does not disclose your browsing activity to that project.
