I don’t know why but i have other search engine on forced safesearch, also when parental control is off, like duckduckgo and ask.com too. Maybe because i use cleanbrowsing DNS? They enforce them automatically.
We are very happy to announce that CleanBrowsing now enforces Safe Search on @DuckDuckGo.
Parents & Schools: DuckDuckGo is now certified child friendly as safe[.]duckduckgo[.]com can be enforced at the DNS level.
