Choose how much Sval blocks

Sval blocks ads and trackers with filter lists. The level you choose decides which lists it uses.

A news site you read keeps loading trackers from other companies, and you want Sval to block more of them.

Steps

The line under the levels says what the level does. The change applies the next time a page loads.

Balanced Blocking is the level a new install starts on. It blocks ads and trackers with lists that rarely break sites.
Strict Blocking adds lists that block more, including trackers in links, social widgets, and scam sites. Some sites might break. It also strips tracking parameters from the addresses you open.
No Blocking blocks nothing from the lists.
Custom starts from the lists of the level you were on. You can then switch lists on or off and add your own. See Add a filter list.
Under a level other than Custom, the card lists the lists in use and who publishes each one. Sval downloads each list from its publisher and keeps it updated.
The level syncs to your other devices.
Leaving Custom for another level asks first, because that level’s lists replace your custom set. Lists you added are removed.
To stop blocking on one site only, turn off its protections. See Turn off protections for a site.

Couldn’t load this list today. The list’s publisher didn’t answer. Sval keeps using the copy it last downloaded.
Couldn’t load this list. Nothing from it is blocked yet. Sval has never downloaded the list. It tries again on its own.
A site breaks after you choose Strict Blocking. Turn off protections for that site, or go back to Balanced Blocking.
