Acknowledgements

Shieldio wouldn't block anything without the volunteers who write and maintain these filter lists. Thank you.

Filter lists

Shieldio blocks ads, trackers and annoyances using filter lists written by the EasyList project's volunteers, plus a short list of ad and tracking servers that Shieldio maintains. Shieldio converts these lists into Safari's content-blocking format. Conversion changes their syntax, and rules that Safari can't run are left out. The list authors are not affiliated with Shieldio and do not endorse it.

Shieldio includes unmodified copies of these lists and converts them into Safari's content-blocking format on your device; rules Safari can't run are left out. The lists are available, free and without DRM, from their publishers at the source addresses above. They are provided "as is", without warranty of any kind. Nothing in the Shieldio license agreement limits your rights under these licenses.

Where the lists come from

A copy of each list ships with the app. When a list expires, Shieldio downloads the new version from the source address above and converts it on your device. The privacy policy describes exactly what those downloads send.

If Shieldio blocks too much or too little on a site, please tell us first: the problem may be in our conversion rather than in the lists.

Software

Shieldio is built only with Apple's frameworks and our own code. It contains no third-party software libraries.
