Is Owl(Sielena theme) safe to install?

Owl(Sielena theme) declares no browser permissions and no site access in its manifest, which is as narrow as an extension gets. We do not audit code and we do not judge intent; what we can show is what the listing declares and whether that has changed while we have been watching.

What data it declares

The listing carries no declaration about the data it collects.

The listing does not link to a privacy policy.

What Chrome asks you to allow

From the permissions it declares, Chrome shows no permission warning when you add it.

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

We have not read this listing's manifest since we started keeping permission names. The counts on the card come from the last time we did.

What the store shows

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.

Who publishes it

Sielena Semper, who publishes 62 listings we track. This listing has been in the store since 2016-04-04 and was last updated on 2016-04-04.

How to check or remove it in Chrome

  1. Type chrome://extensions in the address bar and find the extension in the list.
  2. Open its details. The site access setting shows where it can run; set it to run only on click and it reaches a page only after you press its icon.
  3. To uninstall it, choose Remove on the same page.
