Forget a site

Forget this site clears everything Sval keeps for a site, in every Workspace.

You stopped using a service and want no trace of it left in Sval.

  1. Open Settings › Sites.
  2. In Your sites, select the site’s row.
  3. At the bottom of the site’s page, under Forget this site, select Forget….
  4. Check the list of what Sval clears.
  5. Select the button that names the site, such as Forget example.com.
  • The list shows each part with how much the site holds: settings for the site, fingerprinting exceptions, removed-element rules, Favorites and pins, history, downloads, cookies and site data, caches, permissions, and certificate exceptions.
  • The parts under On every device are removed from your other devices too. The parts under On this device are cleared here only.
  • You can’t undo Forget.
  • To forget a site that isn’t listed, select Add site in Your sites, type the site, then select Add.
  • Forget isn’t offered in a private window.
  • One part of example.com wasn’t forgotten. Sval couldn’t write to the disk. Select Try again.
