Is Stencil safe?

Low risk

Stencil sends the current page URL to its getstencil.com iframe when the app opens.

Stencil runs a content script on all websites and loads its remote app from getstencil.com. When that app reports it has opened, the content script posts details from the current page location back to the iframe, including the page URL and referrer-like location fields.

Where it sends data

Destinations our analysis observed Stencil contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • getstencil.com

    Stencil sends data to getstencil.com. No other extension we have analysed sends data here.
