Is Slice safe?

Question

Is Slice safe?

Accepted Answer

Slice is high risk. Our dynamic analysis confirmed that on every page you visit, the Slice extension sends the full URL of that page to pal.sli.ce.it/fetch_slice.php — a third-party VAST video ad server. The request also includes a persistent identifier (appUuid) unique to your installation, which allows the server to build a history of pages visited across sessions. We observed 23 POST requests to this endpoint in a single session, including a planted marker URL that confirmed the live page URL is transmitted in the request body. Our dynamic analysis confirmed that every time you navigate to a page, the Slice extension sends the full URL of that page — including its path and query string — to api.sli.ce.it/v1/ads/native. This request is used to fetch contextually targeted ads, but it means a record of every HTTPS page you visit is transmitted to the Slice ad infrastructure. The request also includes your app version. We observed 23 POST requests to this endpoint across multiple sites during a single session.
